From Our Readers: “Paul, my husband watches TV in bed most every night.  For him, it’s a way to fall asleep.

Unfortunately for me, the sound is a major cause of insomnia.

He feels guilty about keeping me awake, so he falls asleep on the couch downstairs. That makes his sleep really poor too.

Are there any headphones he could use that would sound good, quiet the TV and give us back our sleep?”   Marsha S. Mass.

PG:Marsha, based on our research, they’ll be sleep coming to your bedroom soon. We found two great wireless headphones that should end the sleepless nights for both of you and maybe even keep Teenage Wasteland from playing to the neighborhood. Get ready for…………..beautiful silence.”

——————————————————————–

It turns out that the field for quality, wireless headphones, is rather small.

 

You might think that would make it easy to find a really great set of “cans” to keep your music or TV listening up close and personal.

But everything is in the details.

So let’s start with what qualities a great set of wireless headphones needs to have to be one you’ll love to live with.

Great wireless headphones need to:

1.) Reproduce clear, dynamic, high quality sound appropriate for their primary use. (more on this shortly).

2.) Be comfortable to wear for a long period of time. Experiencing great sound while your ears are being crushed is a real buzz killer. (Anyone remember the old (wired) Koss Pro 4AA’s?).

3.) Provide a good operating range from the base.

4.) Have long battery life. (alas, the wireless headphone is not yet powered by magic airwaves)

5.) Be easy to recharge or replace the batteries.

6.) Simple to  operate.

——————————-

Since part of our research methodis to first understand how most people actually use the product,

We discovered there were 2 primary needs for wanting wireless headphones:

A.) To hear TV and movies more clearly without driving others out of the room.

B.) To privately experience exceptional music quality with more freedom.

Currently there’s no single headphone that works well for both these uses due to a technology issue, but that doesn’t mean you have to sacrifice high quality sound because of your primary need.

I’ll explain the issue and how each set of headphones can provide a great experience for each type of use.

———————————————————————-

Enter the Sennheiser RS-120 and RS-180 Wireless Headphones.

Our research found that the best balance of benefits, performance and high customer satisfaction for these two primary needs, happens to occur this time within the same brand, Sennheiser.

The depth of experience a manufacturer has in its speciality has a direct effect on their designs. So, here’s a bit about Sennheiser:

Sennheiser is a German company that has been family owned since Fritz Sennheiser founded it in 1945.

They produced their first headphones in the 1950’s for the pilots of Luftansa, invented the first open air headphone in 1968 and have continued to refine and improve every area of related audio technologies. They also produce some of the finest, most respected wireless and wired microphones, under the Sennheiser and Neumann brands, that are the studio standard of the world.

Having been a part of the consumer electronics world for three decades, I was skeptical about whether a truly high quality wireless headphone existed, based on past experience.

In general, there were a lot of sacrifices you had to make just to go wireless.

Such as:

* The infrared (light beam) based systems would cut out as soon as you turned your head away from the base.  Hard to rock out when the music keeps cutting out.

* The Radio Frequency (RF) FM based systems often added a high level of background noise and picked up other signals crowded into their frequency range.

* The Digital RF systems compressed the sound and lost the depth and detail of the music in the process.

* You could rarely travel more than 10-20 feet from the transmitter before it lost the signal.

We called it “No fun…. on a leash.”

But fear not. The engineers keep…..engineering,  and now a few products have become really good, when used within the right expectations. (We’ll explain.)

——————————————————————————–

We’d love to tell you that wireless headphones have turned into Superman, with their signal able to see clearly through walls, leap small buildings in a single bound, and hold onto the base signal with an iron grip even when you’re in the neighbors yard.

We’re not there yet.

But, both these can work great within a quite comfortable range of use, something which just a few years ago, let’s just say, was a very uncomfortable place.

Let’s start with need A:

A.) To hear TV and movies more clearly without driving others out of the room.

 

The Sennheiser RS-120 is a best choice if you want to watch your great new TV

and “Quiet sounds” are no longer your ear’s speciality (or your spouse wants to sleep.)

 

Sennheiser RS 120 Headphones only P1090630 225x300 The Best Home Wireless Headphones Sennheiser RS 120 & RS 180

Sennheiser RS-120 Headphones only

The Sennheiser RS-120 can give you the ability to significantly improve the detail in voices and music, independently regulate volume level to your needs, watch TV alone or with your family without altering their experience or creating a “trip wire” across the room.  (Nice)

Because the Sennheiser RS-120 uses a non-digital system to send the sound to your wireless headphones, it has an important advantage, especially if you want to enjoy TV in the same room while others are listening to the same TV sound (or your surround sound system).

What advantage, you say?

Well, the engineers have not yet, cost effectively, figured out how to translate into digital fast enough to eliminate a time delay in the sound. This is the few milliseconds of time between when the source sound occurs and when the digital reproduction device actually plays it for you.

And it’s not noticeable if you can’t hear the original source playing simultaneously. But when the TV sound is also playing, it produces an echo effect for the person wearing the headphones.

So, if using a quality pair of headphones allows you to really enjoy TV and movies with others again, then the Sennheiser RS-120 will do a great job for two very good reasons:

1.) Sennheiser didn’t make the RS-120’s specifically for TV listening, they made them to be quality music headphones. This means they reproduce a very wide range of superior, quality  sound.  If that source happens be the music and voices on TV, they also come through clearly and with great fidelity.

2.) The RS-120 uses an analog, FM band radio frequency, to broadcast it’s sound to your headphones, so there is no translation delay, ie. no echo.

When testing them in the Boston area, with no shortage of high power airwave signals around, I could quickly tune them to a strong, locked signal within line of sight  of the base at about 60 ft.  That’s as far away from my TV and the headphone base transmitter as I can get and still see the transmitter. You may be able to go further, if you have a larger space, like a room 328 ft. long so you can test Sennheiser’s spec. for distance.

FYI-1: None of the wireless headphones we found or tested would hold a quiet, continuously unbroken sound stream through walls or floors over much distance.  But stay line of sight with the transmitter and you can boogie around a quite respectable distance.

Now will the Sennheiser RS-120 have the same quietness, depth, impact and frequency range as the Sennheiser RS-180 “Digital” wireless headphones we’re going to talk about shortly?

No.  But it will do a great job for exactly what you need it to do: Help you comfortably enjoy high quality music and TV sound with others or alone.

According to our research, the RS-120’s have made a lot of people happy because they can finally enjoy the great sound in movies / programs and understand the dialogue, without rattling the windows.

Here’s a few other details to know about the Sennheiser RS-120:

The Sennheiser RS-120 headphones are a two piece system.

 

 

accessories P1090624 300x260 The Best Home Wireless Headphones Sennheiser RS 120 & RS 180

Sennheiser RS-120 w/accessories

The Base (transmitter) section connects to AC power, has a nicely integrated charging hook to store and automatically re-charge the headphones and a pair of RCA (Red/White, ie. Right /Left) audio cables that connect to your source’s Audio Output connections.

This can be your AV amp Audio Out, Tape Out, etc.  TV or Cable Box Audio out.

On the front of the base are two green indicator lights: One to indicate the base has detected a signal from your source and automatically turned the transmitter on (Labeled On/Off).

Sennheiser RS 120 Front of base P1090622 300x225 The Best Home Wireless Headphones Sennheiser RS 120 & RS 180

The second is the Charging indicator. It shows green to show you have properly aligned the contact points under the headband of the headphones with the wire charging hanger on the transmitter base. (easy to do).

Sennheiser RS-120 Headband

At the lower front edge of the base, below the word Sennheiser, is the transmitter channel selector.  If you have some interference (ie. trouble locking in a clean signal with the Tuning wheel on the headphones) adjust the white switch on the lower front edge of the transmitter to a different channel (3 choices) and re-tune the headphones.

Sennheiser RS-120 Front Channel Selector

The Headphones portion uses 2 (included/replaceable) rechargeable AAA’s hidden inside the left ear cup area. The ear pad section twists to open and close. As mentioned, the headphones headband is designed to hang back on the wire recharging holder on the base when you’re done, so you’re automatically re-charged for you next session.

Sennheiser RS-120 Battery Compartment

 

FYI-2: Although the transmitter will automatically turn off if it has no signal from your amp, you must remember to switch off the headphones when you’re done listening to preserve the battery power, especially if you forget to put them back onto the charger.

I suggest always using rechargeable batteries, as accidentally placing the headphones on the charger hanger with non-rechargable batteries inside can damage your headphones. (and that’s not covered by warranty.)  It also saves money on batteries and keeps more of them out of the land fill.

When the included rechargeable AAA’s no longer keep a full charge (which happens to all of them eventually), I recommend the Eneloop brand rechargeables made by Sanyo which have proven, lasting performance.

Our research found they’re the battery the pros find have both the right voltage and longest lasting recharge performance. (See my “Stop Playing With That or You’ll Go Blind” flashlight review for more details)

Senneheiser has done all it can in the RS-120’s to prevent other radio frequencies from interfering with your sound and for most locations, you will have very few drop outs or weak signal noise, if you use them within the range we tested, in line of sight of the transmitter base.

Unfortunately, you can only know for sure by trying them in your own home. Most people found that the sound quality, comfort, ability to use with simultaneous TV sound and ease of recharging, made the RS-120’s a keeper.

One note: If when you set up your RS-120’s you’re having a high level of background noise and the headphones don’t play with plenty of volume, it is likely the Audio output you have connected to is a Variable output set at a low output level.  See my FYI-3 at the end for some tips to trouble shoot this issue.

The last of the specs explained:

* The RS-120’s can reproduce music within a range of  22 Hz – 19,500 Hz. That’s just about what is considered the full audible range of human hearing, so that’s good.

* According to Sennheiser, you’ll get between 20-25 hrs listening time from full charge to off.

But, because RS-120’s come with the recharging base,  simply put the headphones back on the charger when your done. (it also saves wandering the room to find them)

* They only weigh 8.1 oz. w/batteries installed and users and I found they were light and easy to wear for at least 4 hours (the longest we could be in one place to test them and longer than any movie).

There are two items our research uncovered that users said they would like Sennheiser to improve on the RS-120:

* Out of the box, you must initially charge the headphones for 24 hrs. before using them.

I know, we all want instant gratification, especially after we’ve spent hard earned cash.

But, the initial charge being done correctly programs the batteries for the longest performance.  If you short charge the batteries on the first charge, it’s likely they will never last as long as they should from that point on. And weak batteries equals increased background noise.

I suggest plugging in the base, installing the rechargeables and placing the headphones on the charging cradle for 24 hrs. before you do the hook up.

With them fully charged,  you will be able to completely test the full working system during your hook up.

Or, order a set of Eneloop “Ready to Use” rechargeable’s at the same time you order the Sennheiser RS-120’s and you’ll be ready for instant gratification.

After that, just put the headphones back on the charging base when your done using them and you’re good to go.  Remember, that when the batteries get weak, so will your sound quality.

* They would like the headphone volume control to have a raised indicator, (like the dot on the F/J keys on your computer keyboard) so you can quickly feel which wheel is the volume without removing the headset.  I personally found I could quickly locate the Volume wheel after a short time using them.

Neither of these items out weighed most users overall high satisfaction with the RS-120’s benefits and performance.

So, if you need a quality wireless headphone that will give you hours of listening pleasure comfortably both alone and when watching TV with the family,

Buy the Sennheiser RS-120 wireless headphones with the “Ready to Use” Eneloop Rechargeables (for more instant gratification-about $10.00 for 4).

They’ll put the fun back into group or late night TV and music.

Now for the Best Overall Performance for a Wireless Headphone

Drum Roll Please……………

Enter : The Sennheiser RS-180 Wireless Headphones

 

Sennheiser RS 180 on base P10906466 225x300 The Best Home Wireless Headphones Sennheiser RS 120 & RS 180

Sennheiser RS-180 on base

 

Need: B.) To privately experience exceptional music quality with more freedom.


The Sennheiser RS-180’s produce exceptional sound quality (18 Hz – 21,000 Hz frequency response), rivaling many high quality wired headphones and speakers and that’s saying a lot.

In fact, if you want to experience hearing the spacial depth and detail of a high end speaker system, without the high cost, these wireless headphones will bring that home.

Sennheiser put A LOT of thought into designing this headphone package, as you will see.

It starts with the most important element: Sound Quality.

These headphones incorporate a digital technology called “Kleer”, that keeps the transmission clear and quiet.  And it does it while providing  full CD quality sound (the full 16 bit, 44.1 Ghz) with no compression.

Kleer works very well line of site and the nearly complete absence of background noise gives you the opportunity to experience every detail of the wide musical range these headphones are capable of.

The Sennheiser RS-180’s will also allow you to travel a  good distance from the base, again at least 60  ft. in our in home tests and will operate, according to Sennheiser, for up to 24 hrs. from full charge to off.

The base station is also the handy charging dock.

Their “Open-Aire” design (remember Sennheiser invented the first one in 1968. Quiz later.) creates an ambient, natural quality to all music sources. (but, it does not create an isolation chamber for your ears, so you can still tell when people are talking to you.)

The ultimate design goal is to re-produce music in a way indistinguishable from the live creation. While no one has gotten there yet, Sennheiser is definitely working on it. (the Sennheiser HD-800 ($1,500) are so good it’s chilling.)

Couple that with a Signal to Noise ratio of 85 dBA, an approximate measure of how much signal (music) vs noise (background distortion present in electronics) is added to what your listening to and it means you have a chance to hear really quiet passages with nearly background silence.  The higher the Signal to Noise ratio, the better.

To keep the digital transmission as strong as possible, the Sennheiser RS-180’s automatically selects the best broadcast frequency for you within its 2.2-2.4 GHz frequency range.

For you international travelers, since the digital frequency standard for wireless (and similar devices) is part of an international standards agreement, you can take your RS-180’s overseas. (vs FM based systems are US standard only. Europe uses that FM band for other things.)

In fact, Sennheiser includes the four most common AC plug adapters in the box. You just attach the appropriate adapter to the base power plug module.

accessories P1090655 273x300 The Best Home Wireless Headphones Sennheiser RS 120 & RS 180

Sennheiser RS-180 w/accessories

If the signal from your source is very strong, there is a switch on the back of the base that will calm it down (-6dB) so your headphones don’t get sent an overloaded signal that distorts the sound.

Sennheiser RS 180 Rear Panel 1 P1090679 225x300 The Best Home Wireless Headphones Sennheiser RS 120 & RS 180

On the front of the base are three lights:  Charge, ALC ( Automatic Level Control) and Power.

 

Sennheiser RS 180 Base Front Controls P1090653 225x300 The Best Home Wireless Headphones Sennheiser RS 120 & RS 180

Sennheiser RS-180 Base Front Controls

Power and ALC are On / Off switches. The Automatic Level Control feature is designed to automatically compensate for variable volumes from your audio source, like commercials when you’re listening to TV (alone).

For TV it can be helpful, but I find it’s not an enhancement for most other music sources.

I prefer to leave it off because is creates an artificial pumping as it ramps the louder passages down and the quieter ones up.  But, that’s also why Sennheiser made the On / Off switch easily accessible on the front of the base.

The Around the Ear pad’s velour-like padding and headband design make these headphones very comfortable for extended listening. They also hide the the battery compartments located beneath the left and right earpieces.

The Power, Volume and left and right balance controls are located on the right side earpiece.

The Power button is located between the large + and smaller – volume buttons and has a raised pattern on it.

Tip: To restore the Left / Right balance to center, press both the left and right buttons with one finger simultaneously at the middle of both buttons.

Some users of the RS-180 also wanted Sennheiser to add a raised dot on the + and – of the volume control to make locating them faster when on your head and I agree.  I located them by finding the raised Power button between the two and moving my finger up or down to adjust the buttons.

On the audio connection side, the connection wire is a 3.5mm stereo mini plug.

Also included in the box are the audio adapters for hooking up to standard RCA Audio Out connections (Tape Out, etc,)  or a standard (large) headphones jack, located on the front of many receivers.

Just in case people who love great sound are also cord neat freaks, they included two cord corral’s, one loop that snaps into the back of the base as a cord tension relief and one wire wrap to gather the two cords together neatly at the back.(See the RS-180 Rear Panel photo above showing both installed.)

Sennheiser addresses the need for instant use gratification by including the “Ready to Use” (pre-charged) Eneloop Re-chargeables I mentioned earlier.  The Eneloop batteries hold at least 70% of their charge for up to 3 yrs. on the shelf. So no worries about how old the batteries are when they arrive. (Nice)

FYI-3: Here’s a tip to help hook up your new headphones, if they don’t seem to be playing with full volume:

Outputs on many audio producing products have either a Fixed (ie. constant level of signal being sent out) or a Variable output (ie. it’s signal level will increase or decrease when you raise and lower the main volume control.)

Hooking up to the Variable kind of output takes away your ability to independently control the full range of volume on your headphones control.  You become limited by how high the main volume control has set the volume.

Also, if the output level you have connected to is sending too low a signal, you will hear a high level of background noise or the headphones base may not automatically turn on. (the green base On/Off light will not light.)

So, if your headphones will only play at a quiet level even when the volume control on the headphones is set on max,

Here are two possible solutions to this issue:

1.) Change the audio output you connected to, to one with a Fixed output.  The Tape Out (Rec) connectors are always a Fixed output and usually pass all sources through those connectors.

One exception to this may occur if you are using a “digital” connection from your source to your A/V receiver. Depending upon your equipment, that signal may not play out of the analogue outputs, like your Tape Out.

You can use an analogue (RCA cable) connection from that source to the receiver instead of the digital one. so all the outputs will see the (now analogue) sound signal.

A more cumbersome way, but that retains the digital connection, can be done if your receiver has a “Pre-Out.”

Hook up your wireless transmitter base to it,  turn off your speakers at the receiver, adjust your receiver’s volume control to a 50% level and then control the volume of your headphones from the headphones. The volume on your receiver will set the maximum volume your headphones will play on the headphones Max. volume.

2.) If the component does not act as your Main volume control, but only has a Variable Audio Output, set the device’s volume level to just below max. and leave it there. That will drive a strong signal to the Receiver it is connected to and so your headphones hooked to Tape Out will get a strong signal into them through the Receiver.

Cable boxes often have only a Variable analogue output for audio at the back.  If you’re using an HDMI cable to send the Audio / Video from your HD cable box to your TV or A/V receiver, go into the cable box Menu on your cable remote and find “Settings.”

There is often a volume level setting there you can adjust to just below max. and then exit the menu.  This will provide an excellent, high level output to hook to if you want to only hook your headphones up to hear cable provided programing.(or,for example, if you are not using a A/V receiver / surround sound system.)

Every setup is different, but in most cases, you should simply be able to hook up to a fixed audio output on your A/V receiver or directly to the cable box or TV and be done. (This applies to all wireless headphones.)

FYI-4: If you still have interference noise, try relocating the base transmitter further away from devices that emit radio interference (ie. CRT TV tubes, CD/DVD players, computers, etc.).  Sometimes just a few feet further away or up / down can make a significant difference.

FYI-5: Sennheiser recommends in their instructions (yes, I really read them) an important tip you might not have thought about:

Don’t store your beautiful headphones stretched over an object.

It does look cool to put them on a dummy head or other object. But if that object is wider than the way the headphones naturally hang on their charging base, it’s a bad thing.

Unlike when you’re using them, the headphones can stay over-stretched for days or weeks at a time.

This Can Permanently Stretch Out the Engineered Headband Tension that keeps these lightweight headphones comfortably on your head.

Another reason the designers made them look cool on their stand.

Viva la Musica!
