Pebble smart watch degrades Bluetooth audio quality?
The back story. I purchased a Pebble Steel a few weeks ago and I love it. Except I think I have discovered a limitation of Bluetooth. After setting up the Pebble I went to Best Buy to get a screen protector for it, and on the way I knoticed the sound quality of music in my car wasn't the same as when I went to work earlier that day. Normally I stream music to my Mazda from my S4 via Bluetooth. It has always served it's purpose and sounded surprisingly good, but with the Pebble connected as well there is a noticeable "crunch" or distortion to cymbals and overdriven guitars. So I thought it was just a setting in the Google Play music app and I double checked everything was set to high quality while streaming over LTE. After confirming the settings were correct I chalked the issue up to an update from Google and dealt with it.
Fast forward to Saturday. I just bought a UE Mini Boom Bluetooth speaker. Upon a first listen I knoticed the same sound quality issues as I have in the Mazda, distortion in some of the high frequency. The following Monday I went to work but left my Pebble at home by accident. I was showing my boss the Mini Boom and to my surprise the distortion was gone! Peculiar. So when I got home I did some testing. When the S4 is connected to both devices the sound quality suffers. When it's only doing audio it sounds much better. To the common listener it may not be a big deal, but for someone who is in the sound reinforcement industry it drives me nuts. Has anyone ever had something similar to this happen? I plan on testing get with a few tablets and old phones I have laying around to dismiss the S4 as the only culprit, but others experience and expertise would be helpful.
