They are he greatest things I've ever tested. Definitely 50,000/10 beautiful high-quality nanotube technology. Great IPX66 waterproof technology. Much better than the crappy dental floss looking AirPods. Also, they're super high quality and with multi-uses, I use them before bed at night. Beautiful technology. Best feature is that it vibrates when it charges.
Bottom Line: Yes, I would recommend this to a friend
