4.0 out of 5 stars Didn't work

This is an updated review I reordered these because I found out that I needed to delete my bluetooth app from phone before I connect to the Rockville adapters and these things work how they should I'm totally loving it

3.0 out of 5 stars LOWERS SOUND QUALITY

2025-12-31    -amazon customer

I purchased these to pair two rockville party 9 speakers. They DO connect the speakers to each other, but it lowers the sound level and quality drastically. they can’t be used while charging, they have to be charged first. Came with instructions pretty easy to set up and use.

2.0 out of 5 stars Not true stereo sound

2026-02-09    -Justin

So i hooked these up to 2 separate PA's via 1/8 input, and ran a Left/Right audio test to verify each speaker had their respective channel left to ledtz right to right. Lo and behold, both sides played the left/right audio in a moni setting. Sending these back, gave it 2 stars since the battery did last a solid 5-6 hours, but there's a cheaper option on here and it sounded much clearer and louder snd gave me true stereo audio. Be warned, they will charge you about $5 bucks to ship it back even though they lied 100% about their product. I knew Rockville subs were trash, but their electronics too? Sheeeeesh, never again, and i drop lots of money on PA and car audio every year too
