If anybody is shopping for a portable bluetooth speaker, I highly recommend the BoomBot2. It's a bit pricey, but an excellent portable speaker. Easy to use, and able to get quite loud with little distortion. I haul this little thing all around the house, it's great for listening to audiobooks while doing laundry, cooking, etc. It has a clip on the back so you can hook it to a pocket.
I got mine on Amazon, from a third-party vendor for about $12 cheaper than on the manufacturer's website.
