the item arrived as described in 3 weeks to the US, everything looks good, sounds is good. when i try how it works for a couple of days, i'll leave additional feedback. they fit my ears well. the manual is in chinese and english, but you do not need it to understand how it works. My feedback was to quick yesterday. As my left earbud is not charging and it says Low battery after 1 minute of work. The right bud worked for 2 hours only until it said Low battery. Besides the buds spent all night ( around 10 hours) to get charged. when it is charging on the blue lamp for the right side is working. Not happy. :(
