Review
the Sony mdr-z330bt bluetooth headphones are very good and easy to use. It has a 30 hour battery life, and really nice lows. On the left earpiece, there is nothing to interesting, but on the right, you get a lot of controls
Starting on the top, you get this 3 action button/slider. If you slide it down, this means next song, if you slide it up, then iTunes plays the previous song. If you press it, then it plays the song or answers a call. Yes, these headphones also have microphones. Below that, are your volume controls. There is a button with a raised dot on it. That is the volume up button. The one with a down pointing circle, is volume down. Below that is the Micro USB port so you can charge these headphones from your computer. It takes about 4 hours to charge.
Below that, is the power button. If you press it for the first time, it pairs to the device that it sees. If you press it for 7 seconds, you can pair it to another device. Instead of the conventional beeps, the Sony mdr-zx330bt has little melody jingles.
It is very easy to use, however I had some Problems. Garageband for mac, when I use garageband with the headphones for 30 minutes, Garageband will switch the output device back to the internal speakers. Then it is hectic to go to the preferences and to audio, to select them.
To conclude, The Sony Mdr-z330bt headphones are worth it for it's price. It costs $150.00 for them in Canada, but it might cost different depending on where you live.
Comments
Lag
The lag is caused by an older Bluetooth specification. Headsets need to support at least Bluetooth 3.0+HS to be lag-free. Bluetooth 4.0 and higher are even better. Note that, in the case of Bluetooth 3.0, the +HS (high speed) is important. Straight-up 3.0 will have a delay. Nothing supporting Bluetooth 4.0 and higher will have a lag, provided your Mac or iDevice also supports Bluetooth 4.0.
Microphone
How's the mic quality? Does it sound okay on, for example, audio Facetime?
