Totally agree w/ WOLFINSHEEPSKIN,my Oontz Angle 3 gets me SOOO many positive views from majority of folks who can't believe the sound from speaker for under 50 bucks(year ago off ebay for 30 peanuts w/ free shipping)& size-wise;about as small as 12oz can soda(surprising bass that is defo underrated in my book,tyvm Robb.
I bought this JBL GO Speaker: https/www.amazon.it/gp/product/B00TFGWAA8/
The sound quality is excellent, a surprising feature for such a small speaker. The bluetooth connection works great and the pairing with the phone is immediate. The possibility of answering calls directly from the loudspeaker is also excellent. It is composed of a built-in microphone.
I think this is the best Bluetooth speakers under 50$
