    FORGET EVERYTHING YOU KNOW ABOUT HEADPHONES


    Mo-Fi is the first headphone that delivers real audiophile performance and sound quality on every device—from professional studio gear to laptops, tablets and even your phone. Oh, and Blue has completely reimagined how it fits on your head, so you’ll get both optimal sound and listen-all-day comfort. Because trust us, you’ll want to.



    LET THE POWER GO TO YOUR HEAD Built-in AMP + Premium Drivers

    Blue Mo-Fi

    Mo-Fi is the first headphone that combines a built-in audiophile amplifier and insanely great-sounding drivers for a truly mind-blowing listening experience. Sure, this means Mo-Fi can get loud. But more importantly, it allows for the most accurate sound reproduction—so you’ll always enjoy great-sounding audio, on every device. Frankly, it’s surprising no one ever thought of this before—but hey, they’re Blue. Innovation is what they do best.



    MAKES EVERY DEVICE SOUND BETTER High-Fidelity Audio on any Device

    Blue Mo-Fi

    Impossible, you say? Well listen to this: Mo-Fi improves the sound of every source—from smartphones to studio gear—by reducing the audio workload on your device. The built-in amp provides tons of power so your source doesn't have to work as hard. It all adds up to vastly superior performance and jaw-dropping sound quality.



    EXCEPTIONAL FIT AND COMFORT A Break from Conventional Design

    Blue Mo-Fi

    Mo-Fi is no ordinary headphone. From the multi-jointed design to earcups shaped—gasp—like ears, they've completely reimagined the form and functionality, without any preconceived notions about what headphones are "supposed" to look like. The result feels less like a headphone, and more like a high-quality instrument you can wear. Some call it radical. They just call it Mo-Fi.



    Sonic Electronix Bonus Pack 4

    Each Sonic Electronix Bonus Pack 4 is intended to help you get the most from your new headphones. The package for the Blue Mo-Fi over ear amplified headphones offers you additional peace of mind with a 3-year Sonic Electronix extended warranty on us. We're also giving you an extended 180 day exchange policy just in case you don't absolutely love these headphones. To top it off, you can use the exclusive 15% off coupon on a select headphone amplifier/DAC or headphone accessory of your choice as well as a free $20 Sonic Electronix Gift Card!

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

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.
    Tight

    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.

    Over the Head

    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.

    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.
    42 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".
    105 dB
    Driver Size
    This refers to the diameter of the driver (speaker) on each side of the headphone.
    50 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).
    15 - 20000 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.
    Yes
    Built-in Amplifier
    This refers to whether the headphones have an amplifier built-in.
    Yes
    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.
    No
