Good quality sound and very light but quite flimsy and feels cheap. No problem with connectivity.

I use them while doing chores and generally moving around the room/house. They're pretty good, about the same as sub £20 wired in/over-ear headphones. The batteries are holding up well, haven't charged since the initial and I've used them for around 3 hours total (had them for a week). For around £20 I think they're worth it. Wouldn't buy it at £30+ though.

They don't block out music very well since the pads are so thin so I would not use them outdoors. Get in-ear ones for that. Since the pads are thin and they are on-ears rather than around-ears, your ears will start to hurt after an hour or so.

They're also not great for videos. There's a noticeable delay between seeing something on my ~4ms lag IPS display and the sound entering my ears. I'd say around half a second, likely less but still noticeable.

My main gripes with them is:

The handsfree completely bugs out the headphones in Windows 10. It cannot play both normal sound and communications at the same time so when switching it'll sometimes fail to switch back and gets stuck on comms. Only way to fix it is to uninstall the drivers and pair it again until it starts working. Works perfectly on my iPhone 5s though (and I presume other smartphones). There are no drivers on Windows 7 so it won't work at all.

Also the band is flimsy so it's easy for the headphones to slip off your head if you're not careful.

EVERY time I look at headphone deals/reviews, there's someone complaining of breakages - but things don't break without force being applied and I therefore wonder how badly some people treat their stuff?

If LOADS of reviews commented on a particular failure, (Porta Pro cables, for example) that might be a weakpoint of the model - but I think reviews would make it more obvious if most pairs of these snapped in half ;0

If you expect (relatively) cheap phones to be indestructible whilst you drop them/stuff them into bags/pull them off your head one-handed or whatever, you'll be WIDELY disappointed. Even expensive phones won't tolerate that sort of abuse and I suspect any increase in lifespan comes more from people treating those better BECAUSE they were more expensive and not because they're better made.

The message is "stop treating your stuff like crap" or at least "stop blaming stuff for your own lack of care" - treat things with care and they'll last longer (hell, I got 3 years out of my PortaPros before the cable wonked!!)
