I use headphones all day everyday and these are the cheapest wireless ear phones i have seen with the best quality. very good quality in loud places such as buses and train and the only improvement i would say would be a longer battery life.

Have to see how these had up to use, my previous JBL buds only failed after about 2 years, and i needed a new pair, so i got these Panasonic buds , mostly on trust that they would not be garbage from this brand. Sound quality is excellent to my ear, and as I use them for cycling and running, no sound cancellation is actually a safety feature. Only downside so far is the battery life seems short, and the charge cable may be custom? I tried another USB cable at work when I was caught short, one I use for my over ear phones, and other micro USB accessories, and could not get the charge light up, I had to wait to get to the really short cable they come with to get them to charge again..

I was lucky enough to be able to try these for free, direct from Panasonic to test as part of a their Reviewer Program and I must say they did not disappoint. The first thing I noticed was how lightweight they are. This gave me doubts as to whether they would stay in place, in my ears. I prefer in-ear headphones, but usually find they they don't stay in, so i opt for over ears which I think are unsightly. The full charge time on these is only 90 minutes and i got over 4 hours usage, before having to recharge. But, I also liked that you can fast charge and get a quick hours play out of them, This is great for when you are going out on a run, but forgot to charge them up. By the time you are ready to go out the door, they are ready. The sound quality is very good, but that is to be expected from a Panasonic product. In fact , it is so good, that other people can hear them, so if you are a frequent traveller in the "quiet" section on a train, you may have to be mindful. The fact that they are bluetooth is also a big plus and the remote is ideally placed and easy to navigate. All in all, these are the best in ear headphones that I have used (and not just because I have been given them to review by Panasonic LOL) because they delivery a brilliant sound quality, combined with a perfect fit and long usage time. I would happily recommend these to anyone who, like me, prefers in ear rather than over ear headphones. Especially of running is your thing, because, they definitely stay put.
