    MASSIVE value

    I honestly can't believe the quality of sound for the price, best value cans I think I've ever had, you can't go wrong with this pair But doesn't specify what is left/right ears and the extra 'adapter' cord, what is it for?? no instructions on options for the button

    PRO:

    Very Good Fit, Hq Full Spectrum Sound, Amazing Price, Great Bass

    CON:

    Extra Cord No Details, Yeah Whats Left Or Right, Cord Is A Bit Thin Flimsy, Yeah What's Leftright

    BEST USES:

    Office, Commute, Travel

    BOTTOM LINE:

    I would recommend this to a friend.

    Highly Satisfied

    The great thing about CX 275s is that it provides solution to accessory support for different devices by the additional cord supplied by it. So I can run it any device. I hear a lot of Trance while travelling and I'm very satisfied with its sound quality. Also for videos with low sound pitch this is perfect. Only thing bothers me are its thin wires; my earlier ear phones were damaged due to same issue. Just have to stay cautious with handling while travelling. Rest, its a great investment.

    PRO:

    Lightweight, Good Bass, Great Sound

    CON:

    Flimsy Construction, Too Thin Wires

    BEST USES:

    Portable Devices, Music, Traveling

    BOTTOM LINE:

    I would recommend this to a friend.

    PRO:

    Compact, Good Value, Comfortable, Durable

    CON:

    BEST USES:

    BOTTOM LINE:

    I would not recommend this to a friend.

  • What headphones have a UNIVERSAL microphone for smart phones?

    The headphone models that we currently offer with a built in universal microphone which will work with the majority of devices are as follows:

    - CX 275s - Ear-canal headset with bass-driven stereo sound and excellent noise isolation.

    - MM 70s - Ear-canal headset with lifelike sound, noise-isolating design and volume slider.

    - HD 219s - On-the-ear headset with plush earpads and vibrant sound.

    - HD 335s - Over-the-ear headset with a DJ style flip up right ear-cup.

    - HD 429s - Around-the-ear headset with powerful bass and ambient noise isolation.

    Each model is a unique wearing style and has individual features. 

    Alternatively Sennheiser offers a range of Telecom headsets (http://en-us.sennheiser.com/business-headsets-mic) which can be connected to a 3.5 mm headphone jack on a cell phone via the CBB01 cable.

    NOTE: For any of our headphones that have a model number that ends in a lower case "i" the integrated microphone/control is specifically designed for Apple products and will NOT work with a non-Apple product. If one of these models was connected to a non-Apple device there would be sound through the headphones but no functionality of the controls.
