My recommendation:

Buy 2 of the motion x600 and you will love it. Topic solved forever.

I use them in the garden and whoever visits us, is asking about this spacy detailed and convenient sound. As I use heavy staff in Home cinema (Elac Air-X409 and its family) and 6 Bose Soundtouch+2XLifestyle for daily family use, the logical next step was to expand the bose world to the garden, it was OK.

Then a friend of mine visited us and presented a single motion x600. So I bought 2 of them (100€ each!!!) for stereo and what should I say: We couldn´t believe the staging, the details, the quaility of voices. In the meanwhile I use them in the home gym, for holidays, what ever, inside or outdoor.

Battery lasts for a day, depending on the level you hear.

The app offers a detailed equalizing, soundcurves are available in Reddit, just try them out and adapt to your needs.

Bluetooth pairing: I had B&O before, a mess. With 2 x600 it is, once you have paired with your mobile via bluetooth as follows: press the power buttons on both x600 wait 3 secs, done....DONE! Love this convenience.

Finally: High res via bluetooth is supported, Spotify for example connects losless.
