Windows Phone Thoughts: Bluetake's i-PHONO mini Bluetooth Headphone Kit Reviewed

Contents and Specifications

Figure 1: All that's in the box. I reviewed the BT450Rx-L and BT450Tx combo pack, so the AC power adapter is not present.

The i-PHONO mini combo package contains:

• The Bluetooth stereo headphones (BT450Rx);
  
• A USB power cable (BT450Rx-L - Light Pack) or an AC power adapter (BT450Rx - Standard Pack);
  
• A Y-splitter power cable;
  
• A carrying pouch;
  
• A user manual;
  
• A utility CD (containing electronic versions of the manual).

Figure 2: The left earpiece, folded out. Note the charging socket and the hinged rubber cap.

Rather than a hard plastic band, the iPHONO-mini has a 50cm wire connecting the two earpieces together. The inner surfaces of the earpiece are covered with soft foam. The plastic foldable ear clips are lined with soft rubber to provide a comfortable fit.

Both earpieces, while appearing the same, do have some slight structural differences. The left earpiece has a charging socket that is covered by a hinged protective rubber cap.


Figure 3: The right earpiece, with the microphone, indicator light, and volume/playback rocker switch in view.

The right earpiece has a power/call button at the top, a volume/playback rocker switch at the bottom, and a microphone at the front. An indicator light is present on the outer surface.
