Audiophile, Premium, Best In-Class, Sennheiser

Sennheiser is a name that is synonymous with audiophile products. They have been viewed as a premium, top-tier (dare we say "The" top-tier?) brand since the beginning of time. Laboratorium Wennebostel's time that is. In 1945, Prof. Dr. Fritz Sennheiser founded Laboratorium Wennebostel's, or "Lab W" in a pleasant half-timbered house. Fritz Sennheiser was born with a gift. When he was 11 years old, he saw an early radio that inspired him to build a crystal radio. Again, he was 11 years old. There was no turning back from that day. The following year after founding "Lab W", Sennheiser produced his microphone. From that point on, it was one success story after the other. Sennheiser's technology continued to improve, and "The Bar" continued to rise. In the mid 60's, Sennheiser released the HD 414, the world's first "Open Headphones". That very day changed the future of headphones forever. That very same headphone, the HD 414, not only helped establish Sennheiser as a leading headphone manufacturer, but it sold over 10 million units. It is the best selling headphone of all time, and Sennheiser had just gotten started.

Sound Signature

Sound Staging & Imaging
Sound Staging and Imaging refers to the ability of a pair of headphones to create the placement of instruments and vocalists in a recording. A small sound stage is very difficult to determine where the instruments are in relation to the vocalists, everything sounds like it's coming from the same place. An extra large sound stage separates the instruments and vocalists so that you can clearly tell where each is on the sound stage.
Clarity/Detail
Refers to how clear the headphones audio reproduction is.
Tone/Timbre
Refers to the quality of a music note that distinguishes different types of sound production (voices, musical instruments, etc.).
Bass
Refers to the bass performance of the headphones. Rated from Light bass to extreme bass.
Bass Detail
How accurately a headphone can reproduce bass notes; a culmination of attack, speed, decay and clarity. Attack is how precisely it can begin a bass note without delay. Speed is the ability to continue to attack an array of bass notes without lagging. Decay is the length of time after a bass note ends that the sound is still heard. Clarity is how easily all bass frequencies are heard. It gives perception of loose, tight, or muddy bass.

Headphone Design

Headphone Type

This is the design of the earpieces on the headphones. Some headphones go inside the ear, while others rest on the outside of the ear. This helps you know exactly what type of headphones you will be receiving.

In-Ear: The ear buds go into the ear. Most often, the right and left ear buds are two separate pieces.

Enclosed-Ear: Usually are found on the larger headphones. They rest on top of the ear and have padding for comfort, as well as enclosing the ear to the speaker. This type of headphone helps to filter out surrounding noise.

On-Ear: This type of headphone involves the speaker sitting gently on the ear without going in the ear or sealing it off.

On-Ear
Headband Type

Headphone type refers to the construction of the headphones.

Around the Ear means that the headphones wrap around the ear to provide a secure fit. This is most often seen in active and sports headphones.

Around the Neck means that the headphones wrap around the neck. This is also seen in active and sports headphones.

Earbuds means that the right and left sides of the headphones are separated and will fit securely into the ear. These are small, compact, and user friendly.

Over the Head headphones mean that the right and left speakers are connected with a support that goes over the head and rests on top. This is the typical headphone type.

Over the Head
Specifically For
Some headphones can use an IR Transmitter in your vehicle, while some can be plugged into your media device and be used on the go or at home.
Home/Portable
Acoustic Principle

The basic design of the headphones. There are 3 different types:

Open: Have ports that allow air through the back of the diaphragms, enabling the headphones to sound like the music is coming from an outside source.

Closed: Completely sealed and have no air passing through the diaphragms. Sounds like you are in a closed off room.

Semi-open: Have slots or ports in the back of the cup and are partially open. This allows for a mixed sound between an open and closed headphone.

Audio Features

Driver Type

The physical design of the driver in the headphones.

Balanced Armature:
A balanced armature driver uses a coil wrapped around an armature which is held in between two magnets until it is stimulated by an electrical current. When stimulated, this armature is magnetized which causes it to rotate one way or the other around a pivot point which moves the diaphragm to create sound. Balanced armature driver headphones are generally earbuds and can have multiple drivers in each earbud.

Dynamic:
Dynamic drivers are the most common driver type. They feature a permanent magnet, usually neodymium, a voice coil and a conical diaphragm to drive your music. A dynamic headphone driver looks pretty much identical to any typical home theater speaker.

Electrostatic:
Electrostatic drivers are made up of an extremely thin membrane, usually a coated PET film, stretched between two metal plates. An electrical signal is applied to the metal plates to create an electrical field which, depending on its polarity, draws the speaker diaphragm toward one of the plates which forces air through the perforations in the diaphragm which generates the sound wave.

Planar Magnetic:
A planar magnetic driver is made up of a large membrane suspended between two sets of oppositely aligned magnets. An electric charge is applied to the membrane to induce movement and produce sound waves.

Driver Size
This refers to the diameter of the driver (speaker) on each side of the headphone.
Power Output
Refers to the power output rating (in watts) of the headphones.
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
22 - 19,500 Hz
Audiophile
Audiophile headphones represent some of the finest headphones available. Audiophile headphones produce genuinely outstanding sound quality as well as extraordinary build quality, components and comfort. They are truly the finest headphones available.
Built-in Amplifier
This refers to whether the headphones have an amplifier built-in.
Amplifier Recommended
This refers to whether a separate headphone amplifier is recommended for use with a specific pair of headphones. It is highly recommended that any headphone with an impedance greater than 100 ohms be amplified.
Pass Throughs
Refers to whether a pair of headphones has an output to connect to another pair of headphones.

These work really good. I bought one and it worked so good with the TV in my living room that I bought another one for my bedroom. They work with either transmitter. There is no background noise and they work even if the TV is on mute. The batteries are very easy to replace and they charge right on the stand. I give them an A+.

Unhappy

January 27, 2014

Many of the shows on tv have audio that goes up(action) & down (conversation). I like the audio to be high enough to hear everything, my wife likes audio low. This product has two problems, when vol is up, the audio can be heard by my wife because the audio also goes out of the outside of the headphones . Fixed by placing tape over outside of headphones. Biggest problem, adj'ing tuning(very touchy) to stereo, volume is very low. Vol good if you adj tuning to ONE(mono) ear, not enjoyable to listen to.

So impressed

March 7, 2015

I have been so pleased with these headphones. They are everything advertised to be and have had no issues with them. I have had them almost a year now and use them daily. I can go outside and work while listening to things I recorded on my DVR. Don't really use them for music but if I had time to do that it would be great. I do my housework from room to room and can listen to TV at the same time without having to sit in the room with the TV. They go quite a long time without having to be recharged. I've dropped them many times and they have never had a problem. Simply love them. A great investment.

Amazing!

June 10, 2014

I am totally blown away by these headphones! I bought them as a replacement for an older pair of Sennheisers that were 10 years ago and these were much better. The only thing I don't like is that they fit loosely (and I have a big head). Great for watching TV but if you're out gardening or something they tend to slip off. I use them 100 feet from the transmitter with no reception problems. The sound quality is excellent! And Sonic shipped them very quickly.

March 29, 2014

My wifes hearing has been getting a little worse for a few years. She doesn't want heaing aids just to watch TV so we bought the Sennheiser RS 120. What great results, now she can watch TV and it doesn't have to be blasting me out of the room! Easy to recharge and very light on the head.

Sennheiser is a top quality mfr., and this headset is great! For me the charging stand adds extra value. It appeals to my laziness. The only concern is that it doesn't have a built in equalizer, but after all, who does?

Best range I've experienced with wireless headsets. Some hiss, some clicks when turning head or moving while at longer distances. Very much worthwhile though. It allows me to work around a large shop and still listen to music or television.

Exactly what she wanted

January 14, 2014

Bought this as a Christmas gift for my wife so she can listen to music on her iPhone while doing things around the house, garden, etc. She loves the headphones. Incredibly easy to use--just plug in and go. All adapters and cords that you might need come with it so this one purchase does the trick. Sound is great, range is fantastic. Well worth what we paid and exactly what I was hoping for.

Are these noise concealing headphones??
A shopper on Aug 2, 2014
Best Answer: No they aren't noise canceling! I am very disappointed in these headphones from the standpoint that I have had less expensive headphones of better quality. The Sennhheiser R120 headphones have the good sound that you would expect but the head band is designed poorly and will not stay on your head. I have tried different ways to wear them and none is better than the other. For this I would rate the Sennheiser R120 a 3 on a scale of 1-10 and would not refer them to anybody. Sony makes a comparable headphone to the RS120 that is of much better quality.
