[EX Q]: Nothing much to say. Sound quality was ok. Bass was a bit weak. One of the buds broke out in less than 2 months. It started to sound significantly less without a reason.
[EX A]: negative

[EX Q]: The Roomba 980 performs as stated. Excellent pick up and battery life. The WiFi connectivity is handy for as needed cleaning between scheduled times. We are very pleased with the unit.
