Portable Bluetooth speaker recommendations?

I travel with my job ALL the time. Seldom home for any length of time and was wondering if anybody had any recommendations on a small portable Bluetooth speaker system that doesn't take up a lot of room. I have been using the Cambridge Oontz curve and wedge and they are pretty good. I was wondering what would be a significant upgrade in the 200.00 or less range. I don't watch tv but do listen to music at night but not a big fan of headphone listening. Mainly iPod, iPhone or computer streaming or hooked to a input jack into the speaker. I have a pair of audio engine speakers but are not Bluetooth and not my favorite sound. Maybe too heavy in the bass department. More a fan of good midrange.  Any ideas.
