SOUND By KEF

KEF M500

Sweet, natural and beautifully balanced, KEF’s 40mm neodymium driver is tuned to deliver full range high definition response from 20Hz to 20kHz. Half the weight of conventional copper wire, the copper-clad aluminium wire voice coil improves HF response to enhance musical subtleties and detail. Each aperture in the tuning plate mounted over the drive unit in the acoustic chamber is precisely positioned to optimise clarity, dynamics and bass weighting. Opera or hip-hop, on the move or just chilling, you make the most of every note.



Maxium Comfort

KEF M500

Precision engineered in aluminium alloy and incorporating KEF’s ingenious multi-directional Smart Hinge, the sturdy lightweight frame securely locates each ear cup in exactly the right position. Memory foam in the breathable ear pads automatically moulds itself to the shape of your ear for a perfect fit. As well as maximising bass performance, this means you can listen in complete comfort for as long as you like.



Ergonomic Excellence

KEF M500

Thanks to KEF’s unique multi-directional Smart Hinge, the lightweight aluminium frame automatically conforms to the shape of your head, sitting neither too tight nor too loose, and folds up neatly afterwards. Together with the overall lightness, the breathable and sweat-resistant memory foam ear pads and headband feel naturally comfortable, even for long periods.



Minimum Noise

KEF M500

An acoustic sealing ring in each ‘racetrack’ ear cup provides an excellent seal that cuts out extraneous noise while minimising sound leakage. All you hear is your chosen track in its purest form, while those around you hear virtually nothing.

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.

On-Ear
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.
Home/Portable
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.

Home Hi-Fi
Traveler/Airplane
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.

Closed

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
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.
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.

Bluetooth means that the audio signal is transmitted from your device to the headphones via a Bluetooth connection.

Corded or Bluetooth means that the headphones can be used as corded headphones or as Bluetooth headphones. They have an input in one or both earcups for use as a corded headphone while they also have a built-in battery for use as Bluetooth wireless headphones.

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

Corded
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.
Yes
Connector Type
The type of connection the headphones use to connect to receive the audio signal from a music source. Traditional headphones use an analog 3.5mm headphone jack. Newer technology has allowed digital signals to be sent directly to the headphone using an Apple Lightning or USB-C cable.
Color Shades
Primary color shades of the headphones.
Silver/Gray
White
Material
Refers to materials used to build the headphones. Most headphones are built from some combination of plastic and metal to give you a durable pair of headphones.
Metal
Ear Cushion/Earbud Material
Refers to the material that the ear cushions/earbuds are made from. Ear cushions and earbuds are available in a variety of materials, ranging from basic rubber eartips to plush leather ear cushions intended for maximum comfort.
Leather
Replaceable Ear Cushions
Refers to whether the ear cushions can be removed and replaced. Often times on heavily used headphones, the ear pads can wear out long before the actual headphones. Headphones with replaceable earpads often last much longer than headphones without replaceable earpads.
Yes
Protective Case
Refers to whether a pair of headphones come with a protective case.
Softshell Case
Water Resistant
This refers to the level of water resistance of the fitness tracker. Some fitness trackers are water resistant and can be used while swimming, while others are only splash proof or should not be used near the water.

No
Foldable
Refers to whether a pair of headphones can be folded up. These headphones feature hinges in the frame above the earcups that allow the headphones to neatly fold into a much more manageable size. Folding headphones are perfect for anyone who spends a lot of time traveling and needs a compact pair of headphones that can fit in their bags.
Yes
Ear Hooks
These headphones feature hooks that wrap around your ears for a secure fit.
No

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:
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:
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.

Dynamic
Impedance
The opposition to electric current, a higher impedance means a higher electrical resistance. This is measured in ohms.
32 ohms
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".
03 dB
Driver Size
This refers to the diameter of the driver (speaker) on each side of the headphone.
40 mm
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 - 20,000 Hz

Stylish, Quality Solution

As far as on ear headphones go, these are terrific. Overall build is quality, so both aesthetically very pleasing but very comfortable. Sound is very good, too. Recommend a headphone amp with these, but even still, without that these are still a great solution. Reasonably priced all things considered.

Starting with the looks, these look really sharp. You can tell they are built well and the flat black is nice. If I were to wear a set of headphones around my neck these would be the ones. I'm also not a big fan of on-ear headphones because of comfort but these are so so. I got some light fatigue after an hour. The sound is good. They are not geared towards the bass head since they bass is good but not heavy. They are very clear but can be a little on the bright side. I listen to some old r&b, classic rock and Jazz which they are great for. Hip hop they are ok. I listened to my roommates but I would buy for school, shopping with my lady, etc. where it won't listen for extended hours and want something fashionable. The M400 I tried as well but not a fan
