    Natural sound with decent build quality

    Worth the price.


    Bass is natural, not over or under-emphasized. Mids are excellent. Microphone is clear. Build quality is decent.


    Loudness is not as high on mobile phones (28 Ohm). Treble feedback not the best. Wires too thin and tangly. No carry pouch provided.

    I would recommend this to a friend.
