Callpod makes a variety of cell phone accessories, ranging from the humble charger to the trendy Bluetooth headset. The Callpod Onyx is one of the latter, with a subtle yet sleek design and the promise of great call quality. Unfortunately, the Onyx suffers many of the problems of its sibling, the. We found the fit to be awkward, and we didn't like the buttons either. The Callpod Onyx does have walkie-talkie functionality and the audio quality is average, but that wasn't enough to justify its $69.96 price tag.
Unlike the Dragon and the Vetro, the Callpod Onyx has a very simple design. Measuring 2.2 inches long by 0.6 inch wide by 0.4 inch thick, the Onyx is a slim headset wrapped in black plastic and topped with a black metal finish on the front. It's so thin and small, that it looks quite discreet when worn. In the middle is a slim LED that glows red or blue.
At the top of the headset is a half-circle volume rocker that can be pressed down to act as the power button. As with the Vetro, the placement of the rocker is a little awkward as it bumps up against the ear when worn, and changing the volume while wearing it is a bit uncomfortable. The multifunction button is on the right, though you would be forgiven if you missed it. It's a tiny piece of cut-out plastic and takes a considerable amount of pressure to push--there is little to no give, and we can barely tell if it has been pressed. The Micro-USB charging port is on the left side.
On the back of the headset is a round rubbery "GummyGel" ear bud. It's a bit too big for our small ears and feels uncomfortable when worn, though your mileage may vary. It comes with a thin flexible ear hook as well, which we found to be necessary rather than optional.
