Setup quirks & things to watch for

Not complaints — practical notes from owners that didn't affect the score.

“Grip is warmer, also because it doesn't have a tweeter. But you can reduce treble on the flip 6 as well. It is more powerful than the grip.”
— Speaker_Critic777 on r/Bluetooth_Speakers

“sony is bit louder compare to flip 6 as for bass sony has extra bass but flip 6 sound cleaner”
