Disconnect the Bluetooth of the mobile phone, power on the earbud, then double-click five times quickly, and the language will be changed. Review: I listen to a lot of audiobooks and podcasts and this tiny earbud is great. I've bought several of the same design because they fit my ear very well without the rubber tip. The sound is fine and the battery life is unbelievably long, often more than 8 hours. The one flaw in the design is that the two halves are vulnerable to separating and it's very hard to put them back together. This has happened to several of the previous ones like this that I've bought from different sellers. But so far this one is very solid! Review: Best quality ## Features - The SYSFUN X7 single wireless bluetooth earbud is a product that it is worth much more than the price. It’s a refined and mini, in-ear design, almost invisible after wearing it. Designed to fit snugly in MOST ears, making it great for Walking, Running, Jogging, Hiking, Biking, Gym, Driving, Working, Relaxing, etc. (Please see our image gallery for a detailed fit guide). - The sound quality is not comparable to high-end headphones, BUT it is definitely not junk, no noise, has nice sound for listening to music, audiobooks, and podcasts. It truly excels for spoken content and provides a built-in mic for very clear calls. - No need to worry about running out of power, it’s super long battery life for more than 12 hours of continuous to listening music. For optimal battery health and longevity, please follow the charging instructions in the notes below. - Comfortable enough to fall asleep with, listening to natural sounds all night with the small earbud worn discreetly and securely hidden in your ear. (For the most secure fit, try gently rotating the earbud forward after insertion). - You are purchasing ONE single earbud. Want stereo sound? Simply order 2pcs and they can be paired for a full stereo experience (See Product Description for pairing instructions). To avoid connection issues with other devices, please ensure you disconnect the earbud from the previous device before pairing with a new one. To prevent damage, DO NOT use PD or any fast charger over 15W.

It lasts awhile, and sound quality is actually pretty good! 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by W***E on 18 January 2025* I listen to a lot of audiobooks and podcasts and this tiny earbud is great.
