I have been using these earbuds for 1 year now and now i can say these are the best affordable earbuds at this price. I would buy it again without any second thoughts. Only thing i don't like is its mike quality but at this price it is still impressive. No problem with sound quality. Not a single scratch on earbud. 1 full charge lasts for 3 to 4 days for me which is better than i expected as a student who gives online lecture daily.bapan sarkar
