Good deal for a solid price and W build quality!
Used these earbuds daily for quite a long time and honestly had a great experience. Sound quality was excellent for the price, battery life was reliable, and the front-loading case design made it very easy to use on the go. The funniest part is how they finally met their end. After a long day, I accidentally left the case in my pant pocket and sent it through a full washing machine and dryer cycle. Surprisingly, the case survived and even the earbuds partially came back to life after drying, which says a lot about the build quality. Unfortunately, the audio became muffled afterward, so I'm finally retiring them. For around ₹800-1000, these served me extremely well and lasted much longer than I expected. Would definitely recommend them to anyone looking for budget TWS earbuds with good sound and battery life. Pretty comfortable to wear and had less risk of falling off at least while walking... never tested running with them! I bought them right around dec 2025 and that time price was around 800... Cons: - Sometimes while connecting it auto sets the volume to 100... so you need to look out for those! - While calling you might face issues with the mic... Could be a noise cancellation issue as well - You can face desync issues certain times but they just reconnect themselves

Average quality but good for casual users.
Few things to keep in mind before buying: 1. Quality - Decent quality, obviously plasticy feel you'll get do not expect it to look premium(as shown in product image). Hinge will loose after few use. 2. Connectivity - App service is shxit and never connected with the app after trying for almost 3 weeks also tried to update but no luck. So you cannot tune according to yourself. 3. Voice quality - Pretty good actually. I'm not into music so much but for me it's work good enough. 4. Comfort & ease of use - it's not comfortable for long use mainly because of size, after 20-30 min my ear start to hurt. Overall decent product in budget. Do not have high expectations in terms of quality specially and also no ANC support.
