Nokia on Wednesday aimed at the ultraportable side of Bluetooth headsets and launched the BH-804. The peripheral is the company's smallest-ever earpiece at just under 1.7 inches long and is also made of relatively high-end materials, including an almost entirely aluminum shell. It lasts for about four hours of continuous talk despite its size and builds in DSP-based noise canceling to cut back on outside noise.

The headset uses a micro USB connector to recharge and comes with a desktop charger to simplify powering up. Nokia ships the BH-804 during the fall but hasn't said which countries will release the add-on or at what price.
