Headphone Design

Headphone 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
Earpiece Design

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
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

General Features

Noise-Canceling
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.
Yes
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.

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

Corded
1/4" Stereo Jack Adapter
Some headphones will come with a 1/4" stereo jack adapter to connect the usual 3.5mm jack to a 1/4" stereo plug.

1/4" Stereo jack is a larger audio jack that select electronics have.

Yes
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.
No
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).
14 - 22,000 Hz

Love 'em

August 5, 2013

Very lightweight and terrific sound. Blocks a good deal of the airplane noise which is essential for enduring a long flight. Nice firm yet small packable case included, splitter for plane use, battery etc. Gave away an Able headphone costing more to trade up to this model. Cheaper at Sonix than at Sony outlet. I can't rate in relation to any other models but pleased with purchase.

Good Comforatble but only lasted a year and a half

May 9, 2011

I bought these for my wife for Xmass 2009. She loved them and used them a lot. They finally gave out after 1.5 years. The stereo output quit. All you could hear while watching a movie was the background noises and not the characters talking. That being said Sony told me that they were out of warentee but did offer to replace them with referbs. My wife likes them so much she said she would not want to try another brand or type. So, I will be bying her some new replacements. She said they are comforatable and do the job just fine. Could have been worse.... Could have spent $300 on another brand.

Probably the best headphones yet.

June 24, 2010

These headphones do the job and exceed my expectations. Insane bass that you can hear that subwoofers can't produce. My friend would be talking and pointing gestures at me and I would not know what the language is. Probably the best headphones and doesn't even weigh a pound it feels like. 10 out of 10. There is no way a person can get disappointed from this high definition headphones. The only thing you have to worry about is changing the battery when needed. Usually if you constantly use the headphones, it takes about 3 days to drain the battery. Definitely recommend and buy these headphones. Adjustable to any head.
