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.

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.
Headphone Application

This is the application that the headphones are designed for. Each application has unique features that make it perfect for particular uses.

DJ: These headphones are durable, loud, and will often allow for one ear listening.

Gaming Delivers explosive sound and allows you to communicate with others.

Home Hi-Fi: These audiophile headphones are engineered to produce high fidelity and accurate audio.

Home/Office: These headphones are designed to produce rich, brilliant sounds that the artists would appreciate.

Sports: Designed for active use. These headphones are made to stay in (or on) the ear during workouts.

Kids: Feature noise limiting technology so that your little ones don't damage their ears listening to music too loud.

On-the-Go: On-the-go headphones are lightweight and often fold up for easy storage and portability.

Student: Compact and rugged enough to survive life in a backpack; inexpensive enough to not hurt the wallet of a student.

Studio: Reproduce music perfectly without any coloration. Look here for reference quality studio monitoring headphones.

Traveler/Airplane: These headphones are compact, lightweight, and have a portable design.

TV & Movie
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.


General Features

Noise Reduction technology removes unwanted noise from a signal. Background or ambient noise can be removed to produce clearer speech and enhanced hearing. Typically these Active Noise Canceling (ANC) headphones are powered and use batteries to activate the noise canceling technology. Also referred to as Noise Reduction or Noise Cancellation.
Built-In Microphone
This means that the headphones or earbuds have a built-in microphone. This can be a microphone on the cord, built into the headphone, or even a boom microphone. These mics can be used for music devices like iPods, for Smartphones to make and receive calls, or for gaming purposes.
Headphone Connection
This is how the headphones connect to the audio source.

Corded means that the headphones use a cord to transfer the audio signal.

Bluetooth means that the audio signal is transmitted from your device to the headphones via a Bluetooth connection.

Corded or Bluetooth means that the headphones can be used as corded headphones or as Bluetooth headphones. They have an input in one or both earcups for use as a corded headphone while they also have a built-in battery for use as Bluetooth wireless headphones.

Wireless means that the audio signal is transmitted wirelessly to the headphones.

Home/RF Wireless
Volume Adjustment
Volume Adjustment means that the headphone (independent of the source) can adjust the playback volume. Many headphones and ear buds have in-line volume control, which allows adjusting the audible volume from a switch on the headphones cord. Other headphones have a volume knob on the headphone can.
Color Shades
Primary color shades of the headphones.
Refers to materials used to build the headphones. Most headphones are built from some combination of plastic and metal to give you a durable pair of headphones.
Ear Cushion/Earbud Material
Refers to the material that the ear cushions/earbuds are made from. Ear cushions and earbuds are available in a variety of materials, ranging from basic rubber eartips to plush leather ear cushions intended for maximum comfort.
Water Resistant
This refers to the level of water resistance of the fitness tracker. Some fitness trackers are water resistant and can be used while swimming, while others are only splash proof or should not be used near the water.
Refers to whether a pair of headphones can be folded up. These headphones feature hinges in the frame above the earcups that allow the headphones to neatly fold into a much more manageable size. Folding headphones are perfect for anyone who spends a lot of time traveling and needs a compact pair of headphones that can fit in their bags.

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 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 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.

The opposition to electric current, a higher impedance means a higher electrical resistance. This is measured in ohms.
32 ohms
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
110 dB
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).
18 - 21000 Hz
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.

I just got my RS 170 and I love it to pieces. I can now watch my movies on my giant screen and blow myself away with the sound and not disturb the old folks upstairs. No, seriously... I wore the phones upstairs because I live in the downstairs and the clarity and sound was still in tact and I put them on my sister's head and she was amazed at the quality of the sound and at such a distance. Now we can both enjoy watching a great flick on Friday nights, my level of listening and her level, no more squabbling over the volume. Thank you Sennheiser for your recommendation for the RS 170.

Sennheiser RS 170

January 5, 2015

My headphones just arrived today. First time for ordering from Sonic Electronix. Fast delivery. Took everything out of the box, hooked it up to my Toshiba 42" HD Flat screen. Connected everything, put batteries in headphones, turned transmitter on and Hallelujah, they work like a charm. Took 5 minutes to hook it up. Very easy to assemble. I put a DVD in my Laptop that is connected to my television with HDMI cable, hit the Surround Sound on and WOW ! ! ! I walked down the hallway here at the physical therapy facility, and the headphones continued to receive signal all the way to the receptionist desk which is about 500 ft from my room before they dropped out. As always Sennheiser wins my heart and ears.

Best overall deal!!

February 9, 2014

This product is everything that the salesman at BestBuy told me it would be, if I ordered it from them at a MUCH higher cost! I am very pleased with the performance, sound, and quality and did appreciate the price this company offered.

I can't rate the durability when I've only had this product for a few weeks.

Spouse is happy

May 31, 2014

I like being able to listen the way I want and my wife can set the volume of the TV where she wants it. But I don't like not being able to adjust the headset volume without taking the headset off as the volume controls are small.

Great Product!

January 30, 2015

I purchased a Sennheiser RS 170 to help me hear better when I watch movies and television on my Sam Sung & Bose surround sound system. I listen with the head set and everyone else in the room can hear through the normal sound works great! I highly recommend this headset for anyone (like me) who is having trouble with hearing loss!....Bose said it wouldn't work, Best Buy said it wouldn't ....Sennheiser said it would and it does!....Thanks Sennheiser for a truly great product!

Arlington, TX

Very good product

January 16, 2014

I purchased these for my hard of hearing, handicapped husband. Wow, what a difference this has made to him. He can now enjoy TV and his music with surround sound. He loves them and so do I. I use them to listen to my favorite music. Very high quality product and sound is tremendous. Only problem is the on and off switch is a little inconvenient for him. Has hard time getting into such a narrow spot. Controls are hard to see as they are all black.

Great headphones! RS170

June 10, 2014

I spent a lot of time researching wireless headphones and these are what I ended up with and I couldn't be more please! The sound is fantastic with no dropout at all. I haven't tested the range yet but I haven't reached the limit yet while wandering around my home, including going into different rooms. The only (slightly) negative is finding the correct switch on the right headphone. You get used to it after awhile but it is hard to differentiate which switch is which while trying to lower or raise the volume etc. I have added a drop of glue to the on/off switch to help reference a location.
The other thing I had trouble with, and this is NOT RELATED to these headphones directly....I struggled finding the right place to plug them in. I had to get a different cable box with the red & white audio out output so I could get network TV. Then if I was streaming Netflix for example, I got no headphone output. To stream I had to connect to the red & white TV outputs. It's a pain to be moving the cables all the time so I solved it with an Audio A-B switch box from Amazon. (Reconton VS1002 two way switcher; About $15) Now I just hit either A or B depending on which output I need to listen to the program. Beware, not all of the new cable boxes have the correct output. New Cisco boxes do not. Older Cisco does.
It took awhile but I am up and running and love these headphones which help me decipher conversations better. I have hearing difficulties and this is a great solution. I normally wear hearing aids but don't need them with the headphones. In fact if I do use them I get feedback so it's best to leave them off anyway.

Great Sound!

June 24, 2014

Bought this for myself and a supplemental headphones (HDR170) for my girlfriend. Over the years I bought a few headphones from Sennheiser and always was satisfied. This one doesn't disappoint either. Sound is superb and I never loss the signal from one end of the house to the other. Like someone said about hearing loss it gives us the opportunity to adjust the volume to our own taste. They are lightweight and work on 2 AAA battery. After 2 hours of TV each pair takes only 20 minutes to recharge, although they still have lots of juice.

Sennheiser RS 170

June 12, 2014

I brought these over a month ago, I have a very bad hearing loss and with the tv volume all the way up I could hear ok but still couldn't understand what was said and my wife couldn't stay in the same room because the tv was so loud. Now with the head phone she can turn the volume to where she wants it and I can set my RS170 where I want them,the voice is so must clearer and I can understand what is said. I will never again be without my RS170, great buy and the service could not be better. I will buy from Sonic Electronix next time.
