  • Amazing sound without breaking the bank
    Verified BuyerReviewed by Jerry - July 31, 2021

    Sennheiser knocked it out of the park with the CX True Wireless. Amazing sound, good bass, equalizer works really well, customizable and accurate touch controls, competent companion app, secure fit provides good noise isolation, fast pairing. For a $130 this should be a no brainer, specially for Android users.

  • Amazing sound
    Reviewed by Honeybadger57 - July 31, 2021

    These are buds fit nicely in the ear. I was not sure what to expect with them. They were not overpowering loud. The noise canceling worked great I could not hear others talking when listening to music. I would definitely buy more of these. The sound was crisp and clear!

  • Killer sound!
    Reviewed by My2hands - August 5, 2021

    They have awesome sound and the charge lasts all day. The bass is amazing and they fit into your ears perfectly. I would say they are the perfect wireless ear buds.

  • These are great value for the price.
    Reviewed by HDNguyen - July 11, 2021

    I returned the Sony WF-1000XM4 because after an hour of usage they made my ear itchy and uncomfortable. I returned the Sennheiser momentum because the battery life lasted like 2 hours (mightve gotten a dud). Sound is subjective, but I find these sounded better than the Sony WF-1000XM4 and the Momentum 2. Not having ANC, wireless charging, and automatic stop/play when removing earbuds was not a deal breaker for me. These are also more than half the price of the Sony WF-1000XM4 and Momentum 2. These are the perfect buds for me within this price range.

    Yes, I would recommend this to a friend.

  • Doesn't fit small ears
    Reviewed by MaryM - February 22, 2022

    These earbuds have really great sound quality and the passive noise cancelling is pretty good. The fit is pretty bad for me though. I typically use the small ear pads and while the part that goes into my ear canal fits okay, the body of the ear buds is too big and awkwardly shaped. My ear cartilage has a natural curve in the ear well that the block-like ear buds does not account for. This results in my ears feeling kind of uncomfortable and sore after just a couple hours of wear. Would not recommend for anyone who typically finds themselves using the small adaptive ear pads in headsphones. Too bad, because otherwise these would have been great!

    No, I would not recommend this to a friend.
