Just purchased the headphones. Technical specification great with great sound and specification. A limitation, however is that according to emails from Sony this can only be charged via a PC usb. This limits their use as a PC is not always available - what does one do then? Average overall rating given due to this limitation.

I found these headphones in a large UK retailer after seeing some reviews on line. I had a go with the demonstration model and was pleasantly surprised - very clear sounds, wide soundstage. But this was on a wired connection, and I was concerned about the impact of going bluetooth. I have a Sony NW-ZX2 walkman, and connected to the new headphones via the LDAC, enhanced bluetooth connection. Honestly, the sound is very nearly as good as the wired connection. The bass is clear but not overwhelming, the mids are vivid, and the treble is crisp and clear. The LDAC connection really makes a huge amount of difference. It is rock-steady - I've had no drop-outs at all yet. The headphones work well with or without the noise cancellation on, perhaps losing a little sparkle with the setting off, but, as with other noise cancelling headphones, the wind (I live in Scotland, so this isn't a small effect!) tends to get amplified. The controls are easy and well designed. The only small issue I have is a slight rattle on the left headphone which sometimes appears when I'm walking quickly. Other than that, these really are excellent headphones I'd be very happy to recommend.

Comfortable and effective noise cancellation.they also have a good set of buttons on the headphones to remotely control the connected device. My only point would that they're pretty large compared to other headphones.
