Only downside is the little rubber earbud that comes with it comes off quite easily but as long as you keep it snug and are aware of it it isn’t an issue. **Q: Does this earbud have charging cable? I see yes & no on the site. Which is it?** A: Yes it comes with a charging cable **Q: Can you sllep with them on or does it fall off** A: You could fall asleep with it in but there's always a chance of it falling out. Mine has even fallen out when I was Driving. But for the most part it's alright. **Q: Has anyone successfully paired these earbuds TOGETHER for surround sound? My phone will only play through one bud at a time.** A: These ear bud are to be used one at time they are single ear buds. ## Frequently Bought Together - SYSFUN Single Bluetooth Wireless Earbud, Mini Invisible in-Ear Wireless Bluetooth Headphone 12 Hours Super Long Battery Life Suitable for Sports Work and Sleep - Black - NVAHVA Bluetooth Earbud 10 Hrs Playtime, Single Wireless Earphone, Mini Driving Headset Hands-Free Car Headphone, Cell Phone Bluetooth Earpiece for iOS Android Smart Phones PC TV Audiobook - AIYIBEN Bluetooth Wireless Earbud Mini Wireless Earbud Bluetooth V5.0 in Ear Headphone with 4-5 Hours Playtime Headset with Mic for iPhone iPad Samsung Galaxy LG and Smartphones (Black) --- ## 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.at/products/507895884-single-bluetooth-wireless-earbud-mini-invisible-in-ear-wireless-bluetooth](https://www.desertcart.at/products/507895884-single-bluetooth-wireless-earbud-mini-invisible-in-ear-wireless-bluetooth) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-17*
