It didn't work. Pairing disconnected every seconds between right and left ear buds. I reported and request refund but seller requested to return it which will cost twice from Korea. The other white one worked fine. So if you think you're lucky enough to try 50%, go for it.
the product that i ordered had connection and audio problems, seller told me to reset, not help, or send back..that i have no time....aliexpress doesnt help, and didnt send my money back ( so waistw of money on a device that doesnt work ! dont recomend !!
