The music quality is good and the battery backup is very good, in my case it lasts for more than 10 days on a single charge. The build quality is also excellent but only the features are lacking but it is justified at this price. Overall a good product.

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.

Music quality is good but logo is not there like shown on the earbuds, not so easy to use like putting them out of the charging is so complicated but okay. Value for money product and good quality.

he GOBOULT Z40 True Wireless Earbuds are a perfect mix of performance, comfort, and value. The standout feature is the massive 60 hours of playtime, which easily lasts days without worrying about charging—ideal for travel, work, and binge listening. Sound quality is punchy and balanced, with deep bass that doesn’t overpower vocals, making music, podcasts, and calls equally enjoyable. The Zen™ ENC mic does an excellent job of reducing background noise, delivering clear voice quality even in noisy environments. For gamers and stream lovers, the low latency mode is a big win—audio stays perfectly in sync with visuals. The earbuds are lightweight, fit comfortably for long hours, and connect instantly without drops. Overall, GOBOULT Z40 offers premium features at an affordable price, making it a smart choice for everyday users, gamers, and professionals alike.
