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.

Earbuds
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.

In-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.

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.
No
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.

No
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
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.
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).
10 - 19,000 Hz
Sensitivity
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
Impedance
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.
Black
Secondary Color
A color that compliments the main color of the product.

Some of the best earbuds I have ever owned. Really do sound like a high-quality pair of $300 headphones once you get them in your ear right with the right earbud. Klipsch is top of the line!

On my 3rd pair. This one is going strong for 10 months now. Light music, heavy music, these buds can do it all. I blast Metallica through and through and these fine headphones deliver it - practically with no signs of wear. Excellent noise isolation. They put speakers half as cheap to shame.

Excellent product for price.

August 5, 2013

The S4 Klipsch headphones have a very similar sound quality to their higher price point versions. The only negative I would give this version is that the cord used is a pain. Stiff, not easily straightened. Not a huge detriment, but not quite as comfortable, as the cord can hang out in front or behind you and get snagged on things.

Great product except for one little thing

July 31, 2013

I've bought multiple pairs of s4 phones and if you like in ear these are the ones to get. Very comfortable, holds in the sound/blocks out the rest and if you get them seated right the bass can BOOM. The only neg is that this last pair has a problem with the cord twisting up. It's relaxing a little after some months but not enough. If you can find them without that, they're perfect. Very good product for the price.

Good sound but.....

May 24, 2013

Sound is great once you get them fitted in your ear, but they do not like to stay put. Can't use working out because they will fall right out. Also the cord is a major pain. Constantly kinked. Case is a joke also. They do look nice and have great sound as long as you are not moving.

Excellent earbuds! except...

May 16, 2013

These ear buds are great! Excellent sound quality, good rich bass. My only complaint is that the wire is kind of unruly. It is stiff and doesn't roll up well. The durability seems to be very good though. I have had these for 7 months and I have no problems. I am very hard on earbuds and they usually break after a few months. Maybe it is that stiff wire that I am complaining about that is keeping it together. I don't know, but If the stiff wire is the price I have to pay for durability then it is well worth it.

More than your money's worth!

April 28, 2013

These are the best in-ear headphones I have ever listened to! From clear sharp highs to solid bass with great volume even from relatively low output devices, they are a pleasure to listen to. The angled oval inserts in small, medium and large allow for a good seal in the ear for good isolation from ambient noise. There may be better in-ear headphones, but I'll bet you pay two or three times as much for even a little improvement in sound quality.

Best sound for the money

April 21, 2013

The sound quality of these headphones is better than any I've heard in this price range. Bass, mids, and highs are all crystal clear at all volume levels. I just wish I would have purchased the model with the in line mic.

Side by Side tests by myself (52), my son (26) and his friend (26) found no real difference. Their unbiased opinion slightly favored the $5 spare in-ear-phone over the S4s.

Well worth the money!

February 12, 2013

These are pretty much a bargain. The sound quality is up there with much more expensive headphones. It might take a bit of fiddling to get the correct fit with the correct size ear piece but it's well worth it. The only quibble I have is that the cord stays quite stiff and can be a little awkward. But that's a minor issue - they are well worth the money!
