Just got these QOA Celest WyvernBlack earbuds, and here's my honest take after using them for a week.

Sound Quality: The 10mm LCP drivers deliver surprisingly good audio for the price. Bass is punchy without being overwhelming, mids are warm, and treble is clean. They're definitely darker sounding than I expected - great if you prefer that signature but might not satisfy treble lovers.

Mic Performance: The dual mic setup works decently for calls. It's not studio quality by any means, but clear enough for Discord chats. The detachable mic is handy though the right earpiece connection feels a bit loose - be careful when removing!

Comfort & Fit: The ergonomic design fits well in my ears even during workouts. Noise isolation is pretty good too. Wore them for 3-hour gaming sessions without discomfort.

Cable & Build: Love the detachable cable feature (future-proof!), though the included one feels average. Build quality seems okay but I'm skeptical about long-term durability based on other reviews.

Verdict: For under $50, these are fantastic starter IEMs with mic functionality. Just don't expect premium build or audiophile-grade mics. If you need better surround sound or durability, might want to look elsewhere.
