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.

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.

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.

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.
24 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.
30 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).
5 - 22000 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.

Great for the price

December 26, 2013

Getting these for less than $28 is a steal!
For the price range, these are premium headphones. They have great mid-range and highs! They do great in bass for this price range, but don't expect to be able to tune in more bass to get more bump out of them. They only handle so much before they distort, alas, they aren't overly big drivers or priced for the brand.

The headset is comfortable and well adjustable for a bigger sized head. The pads are nice enough to wear for extended periods of time and the cord does actually keep un-tangled better due to the flat cable. Overall, these are great and I would recommend them to those who want premium quality without spending more than necessary.

I do like my bass, but if I want that much bump, i'll drive my car, as direct into the ears at 20 Hz is not well for the hearing. I enjoy the clarity and all around quality from them. Premium sound that is balanced across all the ranges.

4 on durability due to shorter time of owning, but has held up well to lots of hardcore use.
4 on Look/Design as they could've made them a bit more compact, lots of space in the shell of the drivers.
And of course Sonic Rocks!

Awesome Entry Level Extra Bass Headphone

December 7, 2013

Hello EXTRA BASS lovers,

If you like superb deep bass, rich sound with great highs and mids in a lightweight, very inexpensive headphone, you won't be disappointed. I went on Google and search out several types of headphone with a budget of around 40$ - 60$ and came out with a lot of possibilities and by my great surprise i have found this Sony MDR XB 400 cheaper that what i intended to pay for. As I like a little more bass, i chose this headphone instead of Sennheiser as these are exactly what its all about as its meant to reproduce deep powerful bass like in pro headphones i guess. I own mine since a month now and what i can say is that it delivers low frequency response so well that am loving Sony products and even highs and mids are just mind blowing and I use them not only for music but for listening to all other stuffs like TV at all times. I hear all voices and the clarity is superb. TV watching is much more enjoyable now. Even YouTube videos are more fun. I also use them for listening to music on my iPod and on my HTC One Mini powered by BeatsAudio which is something you will be amazed, it sounds beautiful and way better that without BeatsAudio. For those who own anything that include BeatsAudio, this will be a plus as those crazy output and clarity you will get through those 30mm driver that delivers exactly what you want to hear and that sound experience will change the way you listen to music or watching a movie. If you guys have any equipment that have BeatsAudio, please do not hesitate to BUY this headphone along with POWERAMP, those EQ in poweramp makes a HUGE difference in listening to music in better way of course compare to all other music players :) Delivery was very fast even if am oversea. Very satisfied costumer !

The Sony MDR-XB400/BLU XB Extra Bass Headphones are pretty darn good. The extra bass is nice and the sound quality is great. The price fit my budget as well. They also block out outside noise fairly well. Really, there is only one drawback to them and that is that the way they are made, they creak and pop. Annoying as it is though, they are nice headphones.

Awesome Headphones

March 7, 2013

I bought these headphones for the 'extra bass' and they really deliver. The bass is balanced and not over powering over the music, but is still has that extra umph. The ear padding creates really great noise cancellation and I can hear nothing outside my headphones.

I ordered these at 10am and got them the next day. Really fast shipping. Really happy with my order.

I love it

July 1, 2013

My first impression was that it felt cheap and I was afraid they would break. After having it for a few months now, I grew to love them. The bass is outstanding. I even use these for mixing on my turn tables. Overall, they're a great buy and they last.
