Using QCY T5 for binging Netflix for 1.5 years
Battery life is great, I charge once every 3 days, still going strong, better than redmi buds or airpod clones in all aspects
Durability, these are ipx 4 certified and while Washing my face I've had em fall in washbasin a few.times with tap running when I forgot I was wearing em, yet nothing has happened to em.
Sound quality is also good for the price, it supports SBX & AAC codecs. The passive isolation from proper fitting halves the noise around u so they are.good for hearing protection when riding bike (without playing anything else it's a hazard) & if u just want to drown out noise.
But call quality isn't good in noisy environments as it doesn't have noise cancelling mics
Tried QCY T7 as well, more features (app support, 4 mics, case battery visible with Bluetooth) but crap sound, build quality
If u need for handsfree calls, then get the noise cancelling ones (4 mics) by xiaomi, oppo or realme, those cost around 10k
