Coming in a simple black exterior, the Sony MDR-ZX330BT Wireless Stereo Headset pretty much looks like your average headphones – comfortable, and fits snugly in your head. The ear cups are padded with a leather-like material that sits on top of your ear. At 158 grams, these headphones are light, though the lightness of the device make it look like a less premium product. The headband is sturdy, though it is not padded, which might be a discomfort when wearing for long periods. Most of the controls are located on the right ear cup, which contains the power button, volume rockers and the playback controls – all of which is easily accessible even when you are wearing the headset. A micro USB port is present which is used to charge the internal battery. A microphone is also built in, letting you make and receive calls using the headphones. The Sony MDR-ZX330BT Wireless Stereo Headset contains a 1.18 inch driver unit that would amplify sound without distorting the signal. The Bluetooth connection ensures a wire-free listening experience and if your smartphone supports NFC, you can easily tap it to immediately connect it your device without any hassles.
Setup:I primarily used a Nexus 5 for testing the Sony MDR-ZX330BT Wireless Stereo Headset for the NFC connectivity and the supported NFC Easy Connect app from Sony primarily made for Android smartphones. The NFC Easy Connect app lets you manage all connected devices on the headset, but you can still use the headphones without having to install the app.
The Sony MDR-ZX330BT Wireless Stereo Headset can remember eight devices in its memory, so swapping to any device is a breeze. It took about four hours to complete charging of the headphones but you can still use it even if it is plugged in using the micro USB port.
The audio quality for the Sony MDR-ZX330BT Wireless Stereo Headset is surprisingly better than expected. Lenny Kravitz’s Again echoed an almost precise bass output along with a clear reproduction of the vocals. I also sampled Queen’s Bohemian Rhapsody and vocals are spot on – even at full volume. I clearly underestimated this headphone’s capability in delivering good sound output.
I initially had trouble making the smartphone work as a headset when making phone calls but a quick repairing solved the problem.
While I wasn’t a fan of the four hour charging time, I managed to use the Sony MDR-ZX330BT Wireless Stereo Headset for an entire week before it gave me the red light signaling that its battery is low. Considering the promised 30 hour battery life, it definitely delivered.
