I bought the speakers Omni 10 and 20 a few weeks ago. The sound quality is great, far better than eg Sonos. Unfortunately, the manufacturer shines no attention paid to the software. The 10s are half as loud at the same level, in addition to the current 2 Services neither Youtube, SoundCloud or other common services are supported. In addition, there are always failures of speakers and occasionally the 10 runs without Bass. Often, the Omni has 20 also problems to connect via Bluetooth. If you start the music, it runs from the previous volume setting - not ideal if you had the last time you heard loud and want to next time quietly romantic listening to music.
It is more than disappointing that a manufacturer so much effort in the "Hardware" infected, but no effort in the development of software (services and error / Features) infected. Harman / Kardon really need to rethink and get used to the new clientele. Once the error in the app (one for the PC would also be extremely important) infected, I can very well imagine a 4 or 5 star rating - unfortunately, the speaker will not run without the software.
