What is the opinion of Reddit about the
ECOXGEAR Ecopebble Rugged and Waterproof Wireless Bluetooth Speaker – Retail Packaging – Black?

I just picked up a speaker for the exact same reason. Found mine at Costco but they have them at amazon here.

Its lightweight, puts out good sound, lasts 6 hours, acts as a speakerphone, and is shock/waterproof. Only downside is the range it works but I just leave my phone in my bag and the problem is solved. Best part is its only $36.
