Harman Kardon Onyx Studio 6 vs Devialet Mania

Now this is an interesting battle. These speakers have more in common than they have differences. I thought the Mania and its signature deep bass would blow the Onyx 6 out the water, but well.......The soundtest might prove otherwise. Both speakers are playing music via a Bluetooth connection and streaming directly from Spotify. Note: The Harman Kardon is NOT a WI-FI speaker. Its has no WI-FI streaming capabilities built in like Airplay 2 or Spotify Connect which the Mania has.

Quick Specs
Onyx 5 - Bluettoth 4.2 and 50W amp output with 8 hours battery life (claimed)
Mania - Bluetooth 5 and 176W amp output with 10 hours battery life (claimed)
