First heard of Harman Kardon in 2014 and purchased the Onyx Studio 1, which is still going strong. The Onyx Studio 7 is a an elegant portable sound studio that fills the room perfectly no matter what volume you play it at, nor the varying room acoustics, even outside brings you inside. Love the quality of the sound, if you like a lot of balance and clarity to your music go for it if you want bass you have enough to blow out a window or take down a wall just turn it up. When you look at this speaker from every angle you'll admire the design and expect quality sound; just switch it on, then you admire it even more. Battery, charging, connectivity it does exactly what the specs say. It's solid and robust you just have to hear it then it ticks every box. A proud piece of work all round, fair play to ye.
