    Top Quality
    Fantastic quality,easy to charge and excellent feel. Sound is very impressive as is battery life!

  2. C. E. Dunn –

    Great value earbuds
    I’ve had several different brands of earbuds, these hold a place of their own. Firstly: Their battery life will last forever many hours. I’ve used them upwards of 7 hours straight without dying. The case power life can go days without needing to recharge from multiple uses. Sound quality isn’t quite BOSE but does deliver clear quality. One downside in my opinion, although given various size rubber ear cones I struggle to find one comfortable to fit my ear, maybe the shape, or maybe my ears. All in all excellent value for the price.

    BOULT EARBUDS
    They are not the best sounding Earbuds, but you can’t expect anything more than average for the Price, I just bought them as secondary to my Airpods Pro and my JBLs. But glad I bought them to run around use.

    I generally don’t at all review and also I always preferred some other company like JBL, BOAT, Samsung, but if I say about this product, it is totally remarkable, sound is very clear, bas is jat awsum mic is totally outstanding. They don’t pay me anything to say this, but I don’t know how longvit will work properly, but if it works for 1 year, I will buy it again. In this price quality is fantastic.

    Why did you pick this product vs others?:Nice TWS earphones under ₹1000 . Nice audio, good battery life. However after 1 year of use there was some trouble in charging one of the earbuds in the case. I used to adjust using a piece of paper to make it sit in a position where it continued to charge. Also the case is not waterproof it is not working since I got drenched in rain with it in my pocket. So, decent product needs to be handled carefully.

    This product is absolutely amazing my impression.Good product 👍 you purchase now

  12. Sanghavi Balaga –

    Awesome good quality good product light weight smooth

  13. Jatin jangra –

    the sound quality is really good and the vocals are also pretty clear and if you love bass these are a must buythey connect instantly with my iphone but the connection range is a but less and i also play games using these earbuds i can instantly tell from where the enemy is coming from and the latency is negligible but it does not swith to gaming mode automatically you have to click the touch control button 4 times but the main issue i found was the looks that it came with a rubber finish with looked pretty good but if you touch using oily fingers or scratch it using nails the finish will wear off in a few days overall great product
