They're riddled with design compromises that make it a middling offering instead of a truly trendsetting headset. What I look for is a relaxing, warm and sensual sound that just drifts me away in the emotional experience of the music being performed. How to connect devices via the BLUETOOTH function differs depending on whether or not the device supports one-touch connection (NFC). However, when I'm in my room, which isn't too warm (it's just not cold, either), it bothers me a little how warm my ears get.

If you really value pristine audio, though, you'll probably want to step up to Sony's MDR-1As or something in Sennheiser's HD series. The only padding this is present in the MDR-ZX330BT is on the supra aural ear cups, which is made of the standard ear padding material that I just can’t think of the name of. Even if the connected device conforms to the above mentioned BLUETOOTH standard, some devices may not be connected or work correctly, depending on the features or specifications of the device.With that, one does have to be conscious minded about how they handle these for there isn’t much give to them. Even though it has a pause button beneath the left ear pad, the same button can not be used to continue whatever was paused. If pairing is not established within about 5 minutes, pairing mode will be canceled and the headset will turn off. So, my impression of a product from a company that only deals with refurbished products is quite good.

This is actually my second pair - the first pair (an older model) gave six years of almost constant use (often 12-14 hours a day) and held up through it all. The instructions manual says that the pause button also works as an unpause button, however, not on all devices.

At this time, if passkey is set other than “0000” on the BLUETOOTH device, pairing cannot be done with the headset.

But, while they won't win any awards for being the sturdiest headset ever constructed, they're also incredibly light and comfortable. When the remaining battery charge becomes low, the indicator turns from blue to red, except for pairing mode.The shallow sound lends itself to more songs in the rock and country genres rather than anything in the bass-driven rap and electronic arenas or detail-rich classical music. If you have any questions or problems concerning this headset that are not covered in this manual, please consult your nearest Sony dealer.
