Quite simply, the new Earin earbuds from former Sony Ericsson and Nokia engineers are the smallest, cordless earbuds on the market. The balanced armature speakers that Earin uses are more commonly found in pro in-ear monitors and hearing aids, so you get the best possible sound out of the small package. There are no cords. There are no cables. There is no standard bluetooth wraparound that will constantly rub against your neck while you’re working out. The entire solution is the two tiny earbuds, powered by high-density rechargeable batteries, the stash case that charges them but is also small enough to hang on your keys and a USB cable for recharging the stash case battery. Pair your Earin with your phone, put them in your ears and enjoy your music. They’re so small they’re almost invisible.
