Love the fit and finish of the headphones and the waterproof feature, though the rubbery texture does get caught on my neck when turning side to side, which made me use the headphones with the corded hanging under my chin. But what really annoyed me with this product was the lack-lustre battery life and unreliable charging performance. In the gym when I had the headphones full-blast, they probably lasted just over 2 sessions so I would always charge every two visits, and this eventually forced me to charge after every gym session to ensure I don't run out of battery towards the end of my second session. What was worse when I started using this at work. I currently work in a quiet environment so I often have the volume at what would be 25% level or so, but the headphones would last 5 hours at most. I don't usually use wireless headphones in the office but changing to a phone with no headphone jack had forced me to use them as I don't often carry an adapter with me. Most annoying though was the unreliable charging. I can't charge the headphones unless they're directly plugged into a wall outlet. Doesn't work through a power bank nor laptop/PC. The red charging light would turn on for 5 seconds then switch off. That said, this was using a generic micro USB cable, not the included one. But there shouldn't be any different in these cables, right? I think I've misplaced my original Sony micro USB cable or it's just mixed in with all my other cables, as there was no distinguishing feature on them (no Sony logo). Just seems a bit silly to require a specific, universal cable for charging. Because of these battery/charging issues, I cannot recommend these headphones (especially at the original price), nor any other bluetooth headphones Sony will release. I love Sony and have used their products for a long time but this has frustrated me to no end; considering wireless headphones are meant to be portable usable everywhere, these issues have confined me to using them just for the gym, where I don't have to worry about them lasting for less than 2 hours. I don't think I'll purchase Sony headphones again.

Sony has impressed me yet again with their headphone design. These are a great concept and filled my need for a wireless solution with a small form factor. Some of the top features: - Bluetooth and NFC makes for easy connectivity. - Can be worn in a variety of ways, and there are three arc supporter sizes, and they also stay in fine without one at all (however are necessary if using for working out). Also a number of earbud sizes. - Great compatibility with a wide range of devices and brands. - Splashproof - Battery life is true to the quoted estimates. - Sony sound. This pretty much speaks for itself. Sony sound quality is far superior to its peers. - Wireless! The main reason I wanted these was to listen to music etc at work without wires in the way, and they certainly deliver on that! And for wireless bluetooth headphones, they're packing a lot of punch in a very small form factor. Some opportunities for improvement: - Battery life is in both categories here, as although it's not huge at 4.5 hours, when you consider the tiny form factor that's a pretty solid performance. - The volume can seem a little lower than expected; you might find yourself turning the volume up on your device/the headphones beyond what you would for other headphones. - Although the form factor is fantastic, the earpiece itself does stick out a little from the ear, which visually can take a bit of getting used to. They are lightweight however so you don't notice the extra size at the ear. Yet again Sony has delivered high quality sound in a great form factor which fit my needs.

I bought these to use while I'm at the gym and also for mowing the lawn. The sound is excellent, comfortable ear pieces, has the "no hassle" feel and easy to recharge.
