If you've ever found yourself cranking up your phone's volume to the max, only to get a tinny crackle, you know a phone's speakers just don't cut it. This compact but powerful little bluetooth speaker can hook right onto your phone, or pop off and do its own thing.
The Felt Audio Pulse Bluetooth Speaker, brother of the REWIND Bluetooth Headphones, is a tiny, but boisterous little bastard. Keen to piggyback right on your phone with the help of a FELT Audio case, the speaker will easily slip in your pocket, with or without your phone, and either way will work. When it's not locked into your phone, its back can function as either a clip or a stand.
On top of just being a speaker, the Pulse has an omnidirectional mic, letting it double as a device for hands-free calls. The downside is that you'll have to charge it on its own, and with a 4-hour battery life, you'll have to stay on top of that, but it's a small price to pay some speakers that put out.
