It's roughly iPod Shuffle-sized, but the familiar-looking BH-121 is more smartphone accessory than screenless music player. The square device ships with a pair of headphones and has a built-in 3.5mm jack, should you want to get fancy and bring your own cans to the party (BYOC).

It'll arrive later this month priced at €39 ($53.50) -- or, if you're the clever sort, you might be able to score a free one via Nokia's blog in the source link below.
