The left side stopped working after 1 month and now the right side is going out after 2 months. Don't waste your money. Definitely not worth it ### ⭐⭐⭐⭐⭐ Excellent sound quality *by R***Z on August 26, 2018* I love these! My first wireless, bluetooth earbuds, and I made a very good choice. The packaging says they take 2 hours to fully charge and last about 6 hours. For me, they've taken a lot less time to charge and have lasted more than 8 hours a few times. Clear, crisp sound, easy use volume buttons, and easy tethering to devices (cellphone, laptop). --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/66988561-bluetooth-headphones-wireless-headphones-sports-earphones-sweatproof-earbuds-deep-bass](https://www.desertcart.sn/products/66988561-bluetooth-headphones-wireless-headphones-sports-earphones-sweatproof-earbuds-deep-bass) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-16*
