Audiophile, Premium, Best In-Class, Sennheiser

The award winning Sennheiser MM 500-X over-ear Bluetooth headphones offer you the best of both worlds: the freedom of wireless Bluetooth music and the high quality sound that Sennheiser is known for. These premium over-ear headphones don't skimp on the internals. Utilizing the latest aptX technology, an advanced audio circuit to deliver true high-fidelity sound over Bluetooth, the MM 500-X headphones don't disappoint. Sennheiser's patented Duofol™ diaphragms provide you with incredibly detailed, crystal clear sound. To go along with the convenience of Bluetooth and awesome Sennheiser sound, the MM 500-X's were carefully engineered to provide you with the ultimate in comfort during even the longest listening sessions. Premium soft padded headphone cushions and an adjustable headband ensure these headphones allow nearly any user to wear these headphones discomfort-free for hours on end.

Enjoy Bluetooth Freedom with the Sennheiser MM 500-X HeadphonesBluetooth Freedom

No matter how carefully you wrap and store cables, they somehow find a way to get tangled up. Headphone cables are no different, and the MM 500-X headphones were designed with Bluetooth to give you that wireless freedom. Combined with the built-in microphone, these headphones are perfect for getting lost in your music and managing your calls without getting ever tangled up in that mess of wires again.

Integrated Controls for Easy UseOn-Board Controls

When you're in a groove the last thing you want to do is pull out your phone to adjust the volume or skip a track. These headphones have eliminated that inconvenience by integrating volume, track and phone call controls into the right earcup to give you total direct control of your device. You'll never have dig your phone out of your pocket, purse or backpack to control your music or answer a call again.

Collapsible Headphones for Easy PortabilityPortability

Let's face it, as much as we would all like to never take off our headphones, there comes a time where we just have to. While the MM 500-X's are best served being listened to, Sennheiser engineered them with collapsing hinges with those non-use times in mind as well. When collapsed, these headphones are incredibly compact, making them both easy to transport and store.


We can't imagine that another set of headphones offers this much sound quality and convenience for anywhere near this price, making these the best all-around, reasonably priced set of headphones we have heard yet.

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

Enclosed-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.

Around the 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.
Home/Portable
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

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.
100 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".
107 dB
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).
15 - 22,000 Hz
Audiophile
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.
