The lads over at Sound & Vision were among the most fervent to review the Foxl portable, a 14cm speaker with integrated lithium-ion battery, 3.5mm jack and USB-in for US$180. (There’s also a Bluetooth version for US$250.) We’ve seen these tiny speakers before, and they’ve definitely gotten better over time. But this Foxl unit caught our eye because Sound & Vision simply gushes over the audio quality, comparing it to systems 10 times the price.
