Wireless sports headphones

I have too many doubts before purchasing it. Like dynamic driver which will lessen bass quality, build material, fitting on ears, originality ( I purchased it on Amazon, it's old { I opted for the old wishfully}, it's from New Delhi, it's non returnable). When in hands my doubts are gone. It's even not used by anyone before me. Battery slow drainage is it's proof. Bluetooth connectivity is awesome with delay of course. I connected it to my 2 Redmi Note 10 pro max, and one iQOO Neo 9 Pro successfully. Coming to it's sound, I am bass head used lots of china philips headphone before. And classic stereo lover instead of ambient dynamic sound. From that point this head set failed to suffice me . This is deep bass set, and in reality it lacks it due to dynamic driver provisioning. It only acts according to my mobile sound signature. Like when on deep bass the head set acts a bit not too high beating of music until I manually change the equaliser. Then the sound is a pleasure. Generally bass is medium and it never overpowers low, mid or highs and it's good. Bluetooth volume is low compared to 3.5mm jack input sound. But again listening on 3.5mm jack is pain due to less noice cancellation compared to bluetooth sound. Build quality, battery draining , are excellent. Never expected the small battery would last so long after single recharge. Even better than OnePlus buds wireless z2. Both have neodymium drivers. My ears are medium so the cups fully covered these. I really like the female person promt inside headphone after some important actions like "power on". Type c port in 2021 batch headphone is an advance thinking. It supports fast charging too. Auto connection is awesome. Had to buy 3.5 mm jack 4 pins male to male jack additionally. 1 extra pin for microphone support in headphone. Frankly speaking, the microphone in the headset didn't offend me. I always hear clean sound through it when testing. To sum up , I can say, my pockets is not wasted. For the sound quality it's 5 star, build quality 5 star, bluetooth connectivity 4.5 star, battery 5 star, design 5 star, sturdyness 5 star. That's all
