I have used the same iPhone 5 for the past year. And I usually stream my music from the iPhone using the Karma's Bluetooth. But beginning a few weeks ago, the audio volume when streaming music over Bluetooth has diminished so much that it is basically pointless to try to use it. You have to turn the volume waaaaaaaaaaaayyyyyyy up just to barely hear any sound. I'm going to have Lormax look at it in a few days, but I wondered if anyone here had experienced a similar problem?
