    ★★★★☆
    Great sound, affordable earphone

    This is my first purchase of the Sennheiser product replacing my old earphone and am really amazed at the superb and clear sound quality. Have been using it daily for 2 months now. Even there are some bad points given, overall I m still happy.

    PRO:

    - well and solid built - comfortable earbuds - clear and detailed sound - punchy Bass that suit to my usual listening

    CON:

    - lacking in the stereo surround sound. - when the cables rub against the clothes or body, that disturbing sound travels to the earphone. - the CapTune app does not integrate to streaming aerobics which I m using such as Spotify, therefore can’t customize the sound.

    BEST USES:

    Listening to music

    BOTTOM LINE:

    I would recommend this to a friend.

    PRO:

    Nice sounding nice bass and very responsive

    CON:

    Does not have stereo sound

    BEST USES:

    Music and general use

    BOTTOM LINE:

    I would recommend this to a friend.
