Getting additional sound while out and about, camping, reading a book outdoors, or sitting by the pool is something everyone can appreciate. The Note 5 speaker is decent, but a portable bluetooth speaker will be even better, and they'll charge the phone too, if needed.
JAMBOX is one of our favorites for the quality sound output, and the newer Jambox Mini is certainly something you'll want to buy for your phone. Quality music output, conference call features, and more makes this a must buy. It's loud, clear, looks good, and can recharge the phone at the same time. A shout out goes to Braven, as they cost a bit more, but sound even better.
