It did die on me when I used it 3-4 hours straight. Sound quality was ok I guess for the size of it I can’t really complain. Comfort is good once you get the correct sized earbud for your ear, it comes with 4 different sized I believe. Overall I would recommend this earbud because it is discreet and unnoticeable to the eye.. if you are constantly on the phone the battery is ok but not the best. Why I rated it 4 out of 5 is because I returned it because it personally did not fulfill the use I needed. I needed a reliable battery that would last. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Love using this in the shower *by C***G on Reviewed in the United States on August 23, 2020* Love using this in the shower to listen to podcasts and audiobooks. Volume is plenty loud. Don’t really use it for music. The magnetic charger is great! --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/89093650-nb3-ip68-waterproof-mini-invisible-wireless-bluetooth-earbud-blue](https://www.desertcart.tn/products/89093650-nb3-ip68-waterproof-mini-invisible-wireless-bluetooth-earbud-blue) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-08*
