I connected 2 sets of powered Bose Companion 2 Series II speakers with same volume level and both had exact same quality in my ears. I love making them for my friends and family also! Ironically, I havent been able to lose this one but will buy another when I do. So I ordered the 9. Wish they came in 10. Fix the cord and charge more - Im good with it! Its also good for safety reasons. The "change" pocket has a divider sewn in so its a no go also. I really like the versatility of this wireless charger. Je ne suis pas déçu , cest une enceinte à la belle finition, du lourd !
