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.

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.

This is the lifestyle that the headphones are designed for. Each style has unique features that make it perfect for particular people.

Headphones need to be affordable and durable to keep up with the student lifestyle. A variety of styles can be considered a pair of student headphones.

Those that often find themselves on planes or on the road a lot. These headphones are compact, lightweight, and have a portable design. Some of the headphones in this lifestyle will feature noise cancellation technology that will help shut out outside noise.

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.
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.

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.

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.
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.
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).
30 - 20000 Hz
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".
98 dB
Driver Size
This refers to the diameter of the driver (speaker) on each side of the headphone.
30 mm
Driver Type
The physical design of the driver in the headphones.
The opposition to electric current, a higher impedance means a higher electrical resistance. This is measured in ohms.
18 ohms
Primary Color
This is the main color of the item.

Great value

July 25, 2013

I bought this for my son, for when he goes to visit his mom in Texas. I have the Bose right now, though I dont prefer them over my previous ones, the Sennheiser PXC 450 (which are the best Ive ever used), but I fly 2-3 times per month for work. My son usually visits with his mom 2-3 times per year. I usually dont leave reviews on products, primarily because im busy and forget to, but I was looking at a pair of headphones for my daughter and happened to see these again, and the review someone had left on them. I want to start off by saying I have used these, I was the one that set them up for my boy. They are VERY lightweight, and have very soft, and comfortable earpads. The headband is adjustable, so they can expand, or get smaller, and luckily enough the smallest setting fits my son perfectly. My only complaint on these would be the lack of support, or maybe headband padding would be the proper terminology for this reference. I suppose if my hair was spiked up, or if I had any hair to speak of on top of my head then those little strands may provide a little more padding. Seeing that I haven't had much hair to speak of for the last 10 or so years, I dont know how the headband fits in that scenario. I cant imagine my money going any further than this. They are light, comfortable, and THEY ARE SONY! that is the price that all those off brands cost. I cant imagine anyone who would complain about the performance of a cheaper Noise Cancelling headphone. I spent a little over $300, and they certainly sound like it too! But I would ALWAYS suggest that potential buyers ALWAYS look at the percentage of noise cancellation. The difference between 90 and 98-99% is a VERY big difference. These do a great job, and they are perfect for a budget friendly pair of headphones that will help cancel out a good amount of noise. Don't let uneducated people bash a product that they no nothing about, and make sure you do your research. It cracks me up reading some of these peoples reviews when they talk about it not cancelling out everything, and then saying they certainly don't meet their expectations. I wonder, what did you expect? Thats what you pay for 2 Happy meals at McDonalds!!! HAHA! Good value, price is right! But buyers beware, these headphones will not go to work for you, and clean the house, or do the dishes Hahaha!

These headphones are light weight and nice for walking. I tried wearing them while cutting the lawn but too much noise. Great product for all the other things I do.

Sony MDR-NC8/BLK - There Is No Noise Cancelling

July 14, 2013

This product is marketed as an active noise cancelling headphone. But noise cancelling is insufficient compared to other noise cancelling headphones. So, I regret to buy this headphone. It is waste of money.

You can use this headphone just like an ordinary headphone. But it is not a noise cancelling headphone.
