Continue around that outer edge and you'll come to controls for speakerphone, Bluetooth pairing and a feature B&O calls Connect. Connect serves as a play/pause button of sorts that resumes playing the last thing your were listening to. It even reconnects to the last device you were using with the speaker. While there is a BeoPlay app for iOS and Android, I had no trouble connecting both my Moto X and my MacBook Air to the A1 without downloading the extra software.
In terms of sound, I was actually quite surprised by the audio quality of the rather compact A1. Not only does it get quite loud without distorting, the speaker offers a range of tones smaller Bluetooth options typically don't. There's plenty of low end for a fuller sound and the speaker's design blasts tones in 360 degrees, maintaining clarity the whole time. I found myself using it laying flat almost always, perhaps because I don't have a coat hook to hang it from. The A1 sounded great on my desk, kitchen bar and dining room table -- all places I could see myself using it on the regular.
The B&O BeoPlay A1 comes in two colors: natural (silver/gray) and moss green. If you're looking to nab one, you can do so today for $249 (£199). That's $20 more than Beats' Pill+, but $50 less than the UE Megaboom. There are some other features to consider with those two alternatives, but sound-wise the A1 bests them both. Sure, there are cheaper options, but if you want a solid mix of sound, design and portability, B&O's latest checks all three boxes.
