      Very quick shipping, item came carefully wrapped. The box was a little damaged, but the earbuds were in great condition. I had this kind of Sony earbuds for a long time before they died and this is my replacement. These are just like my old pair, real Sony brand quality!

      Sony Wireless earphones

      These Bluetooth earphones have a wireless setting that is used for both cell phones and computer devices. I really enjoy using these earphones as they work well and that they have good frequency or pairing connections. The box comes with a charging cord used to charge the batter for the earphones as the battery life is long and extended to use to listen to music or as a mic. I would recommend these earphones for people that want a portable earphones that they can access and not have to connect to a circuit on a device.

      Good for listening to music

      This product is easy to use and charge. I was planning on using this device to make phone calls while working from home; however, the microphone is built into one of those small side pieces. So it is hard for the caller to hear me, unless I speak very louder or hold up the side piece. The quality feels fine; however, the magnets in the actual headphones are not strong at all. The cord that connects them moves around, more than I expected, when I wore the headphones while walking around. The sound quality is great and I do wear them time to time when watching something on my phone or listening to music. I think these are good for the price if you just want something lightweight and easy to use for music and videos.

      Lightweight with great features

      I received this product very far from America, namely in the European country Georgia - (Tbilisi), and I was wondering when it would arrive and I would test it. It is a really good product and if you are thinking of buying this product, don't hesitate and buy it. I received the earphone as described. The sound of the music is good and the bass is balanced so that it does not sound excessive. It is also very light. thanks!

      Extra Bass

      The extra bass is a much sought after feature. Also the 15h run time. Plus the ‘tethering’ of the ear buds so as not to be missed placed as those individual ear buds tend to do.

      Just what I needed…

      …no phones near my head is good and with the Sony I get that plus remarkable sound w/ real base. Apparently the wireless ear buds are amazing also but put radiation right into your head while the neckband type (like the Sony) put out far less radiation - very cool!
