Much tested, landed here

Over the past months I have several devices tested, including
Bose SoundLink mini pretty remarkable sound, long term, good for traveling, but comparatively expensive
Lenco Grid 7 quite well, but annoying and loud announcements when switching
Kingone K5 inexpensive, nice design, good take away, sound acceptable for the price, but annoying announcements in Chinese and English on power
Sonos Play 1 very good (mono) sound stage, but inflexible software connection, too little connection options, in my opinion, too focused on fee-based streaming services, expensive

The Edifier boxes offer an amazingly good value for money, outperform more expensive devices in the sound quality, crystal-clear highs, rich bass, super stereo playback, tone control on a box, remote, very beautiful workmanship I would buy again or the larger model Studio R2000DB. For someone who use its Bluetooth speaker stationary and do not carry around with you want a very good solution
