I used these for about a year when I first bought them (about 3 times a week), but I haven't used them at all recently, so I'm putting them up for sale. (I have charged them for the listing and confirmed that music can be played normally.) If anyone is interested, please consider purchasing them. Please note that the USB cable is a Sony product, so please consider purchasing only if you understand this. (I have always charged with this cable, which is shown in the photo.) *Recently, there have been many cases of receipt fraud on Mercari, so please understand that no claims or returns are accepted. Also, please understand that this is a used item and will be stored and cleaned by an individual before shipping.

Because it "doesn't block your ears," it doesn't interfere with your daily life. The approach of a car, announcements at the station, conversations at work or at home, etc. - times when you had to give up music for the sake of your daily life. With ambie, you can enjoy music without worrying about missing important sounds. With a built-in microphone for calls, because it doesn't block your ears, your voice doesn't get muffled, and you can enjoy conversations naturally. With natural call quality and wearability, even long telework sessions are surprisingly comfortable. While it cannot be completely suppressed due to the structure that does not seal the ears, sound leakage is suppressed to a level that does not interfere with daily use thanks to the unique sound conduit technology. #ambie #WirelessEarphones #Earphones #Ambie
