Our favorite wireless headphones from last year were Jaybird's X2 earbuds. These Bluetooth earbuds packed all the electronics and radios in the ear pieces, requiring only a flat cord to connect the two ends behind your head. I thought they were great for bike riding and jogging, and the interchangeable tips (supporting plastic ones or Comply foam tips) made them comfortable for me to wear. The 9 hours of battery life was pretty good, too. But for some people, they X2's design was still too bulky; the weight distribution of the electronics made it necessary to use the "wingtips" to wrap the earbuds around your ear to keep them in place. Jaybird's new Freedom earbuds solve that problem completely.
The new Jaybird Freedoms are significantly slimmer than the X2s, while retaining the same 6mm driver that gave the X2s really good sound quality (for earbuds). It's almost shocking how small the new design is, which now can completely fit into small ears without sticking out and dragging off the lobe. Jaybird (which was recently acquired by Logitech) accomplished this in two ways: incorporating a tapered driver design so that the tips are smaller, and putting all of the battery, electronics, and radio into the volume control module along the cable. The redesigned driver and relocation of the electronics don't appear to have changed the sound quality (and there's still a built-in microphone), and Jaybird is also pushing a new companion app that allows for real-time EQ adjustments and downloadable presets.
