AUDIOPHILE, PREMIUM, BEST IN-CLASS, SENNHEISER

The Sennheiser HD 650 Headphones Offer an Incredible Listening Experience

The Sennheiser HD 650 Hi-Fi Professional Stereo Headphones will put you right in the middle of your favorite artist's recording sessions. These premium audiophile-grade open-back headphones were carefully designed to provide you with truly natural sound image to make you feel like you're sitting in the same room as the music you are listening to. These superbly balanced headphones provide the classic Sennheiser sound quality you're accustomed to. Hand picked components, special acoustic materials and out-of-this-world engineering ensure the HD 650's provide you with the absolute best sound possible. The HD 650 will captivate your senses and offers total immersion into a sea of music; letting you completely disregard your surroundings and be taken away into your imagination. Life truly is too short not to treat yourself to the phenomenal listening experience of the HD 650.



The Sennheiser HD 650 Headphones Offer an Incredible Listening Experience LEGENDARY SENNHEISER SOUND

The HD 650's feature such authentic, natural sound reproduction that you'll never want to take your headphones off. Innovative technology like a specially developed acoustic silk and hand selected drivers all but eliminates harmonic distortion while the lightweight aluminum voice coils provide a lightning fast transient response time. The open back design completes a truly immersive listening experience.


Comfort to Match the Sound Quality LUXURIOUS COMFORT

Immaculate Sennheiser workmanship created in the HD650's, some of the most comfortable headphones ever designed. The elliptically shaped earpads fully enclose the ear, providing both a natural, comfortable fit as well as outstanding noise isolation. With luxuriously padded earcups and an amazingly soft headband, you will be able to enjoy hours of absolute comfort while you get lost in your headphones.


SPECIALLY DESIGNED OFC CABLE OFC Quality Sound

Sennheiser spared no detail when designing the HD 650's, including the cable. Sennhesier specially designed a high quality 100% Oxygen Free Copper (OFC) cable for the HD 650s to ensure your audio signal's are never distorted. This resilient detachable cable features a Kevlar fiber reinforcement for incredible durability.


I found the HD650s strike an incredible balance of presence, reality, resolution, and detail, all while still managing to be just plain fun to listen to.

    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.
    Large
    Clarity/Detail

    Tone/Timbre
    Refers to the quality of a music note that distinguishes different types of sound production (voices, musical instruments, etc.).

    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.

    Over the Head
    Specifically For
