“Highs were played with crystal clear clarity and the mids provided a warm, rich sound which is especially good for vocals and instrumentals. For my testing, I spent most of my time with a Samsung Galaxy Note 4 connected to the Audioengine B2 using Bluetooth and despite the fact that I was on Bluetooth, the sound quality was surprisingly good. I was actually hard-pressed to tell the difference between the phone connected via Bluetooth or connected via wire. I also spent quite a bit of time placing the Audioengine B2 in different places in the room such as bookshelves, tables, countertops, etc. and the speaker performed very well in both sound and connection quality.” —— custompcreview.com
