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.
Refers to how clear the headphones audio reproduction is.
Refers to the quality of a music note that distinguishes different types of sound production (voices, musical instruments, etc.).
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.

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.

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.

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.

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

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".
100 dB
Driver Size
This refers to the diameter of the driver (speaker) on each side of the headphone.
11 mm
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).
20 - 20000 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.
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.

Best In-Ear Headphone For The Money

March 21, 2014

I have tried many, many earphones over the years, all of them eventually fail from use so what is the point of spending a lot of money on them if you will just have to replace them in 6 months? NuForce 600x sound better than any other i have tried, they have larger drivers and that makes all the difference but that also makes the earphone heavier and so keeping it inside the ear is a bit of a problem. I have small ears and have trouble finding a suitable outer tip to keep the drivers in place. Also the cord is heavy duty and that adds weight as well so a clip on the cord would help a lot. Otherwise they are superior to any other earphone even twice as much money.

Great earbuds for the price!

October 6, 2013

I had read about these being some of the best earbuds when it came to bang for the buck. These do not disappoint. I think I got mine for around 17 or so. I think normally they run 25-30. But these sound WAY better than the 15 dollar ear buds I had before them. Excellent highs and lows. Very clear and crisp. I think it helps that they have an all metal housing. Do these compare to something from Klipsch or Sennheiser? It's hard to say. Probably not when it comes to nuance but from what I've read so do compare them to the very high end 150-300 dollar earbuds. Regardless I definitely agree that these are the BEST earbuds you can buy at this price point. I'm definitely going to buy another pair or two.

Forget beats by Dre... I rather have these! I named it O-Beats!

October 21, 2013

I feel stupid for wasting nearly $100 bucks for a pair of beats by Dr, when clearly I should have bought these a long time ago. Honestly, Beats by Dr in ear headphones are very similar to these but doesn't have the bass compared to O-Beats. For 1/5 of the price of a beats headphones, these headphones rocks! Ideally, these headphones are for people who listen to a lot of hip hop and etc that requires that extra bass and these headphones delivers! Beats headphones are marketed to the young hip hop crowd anyways.... They listen to a lot of those type of music but are pretty much sheeps when it comes to looking cool and being ignorant about choices. I rather stick with my O-Beats that clearly in my opinion is one really good headphones for its price and clearly a good choice for any body planning on replacing their stock headphones. The flat cables are greats and from a distance, you might mistaken them for beats headphones instead. I wish they had them in more colors. Of course, I'm no audiophile, but I like to listen to music and I'm on a budget unlike my deep pockets audiophile brethren who are annoyingly critical for any tiny spectacle of dust and over confusing my decision to purchase headphones!

I like how durable they are, also how they block other sound around..I had problems with other brands, for ear buds not staying in my ears, but these felt perfect, doesnt hurt my ears. also the cord is sturdy and great quality!the music quality is fabulous, just be careful dont listen to it too loud, My ears were hurting a bit, after listening to music for hours. Overall, i love these ear buds.

Well made and good sound

August 12, 2013

These headphone are well made, not like the cheaply produced Bose in-ear headphones. The sound quality is very good, especially the mid's and high frequencies. The would be perfect if they had a bit more bass..

Look nice, sound GREAT!

August 8, 2013

I first saw these mentioned in a WIRED article and they were highly rated as well as selected for "best value". I bought a set and was not disappointed. I have various MP3 players, I'm a self-professed gear pig and I have lots of headphones. I also play bass in various bands and use in in-ear monitors. These do the job very, very well. Being a bassist, I am predisposed to wanting the lows and these produce cavernous lows (as well as pretty much all the other frequencies)! When used with either my iPod or my on-stage headphone, I am not disappointed. The seal in tight and I only hear the board mix I send to them. Except for a pair of (more expensive) Klipsh in-ears, these are my main choice for personal listening.

Great sound!

September 17, 2013

Great sound at a good price. Nice bass; big sound for ear buds. My biggest challenge is keeping them in my ears. I've tried several tip sizes, but they still fall out. Since the cord is heavier--a good thing--gravity plays its part as well.
