On the previous firmware the microphone on this speaker was excellent for phone calls. I updated the firmware only to find out that the microphone is now a lot more distorted when it records audio or is on a phone call. I returned the speaker and got a replacement and it was a repeat performance. Perfect call quality on the previous firmware and as soon as the firmware was updated to 2.6.0 the microphone quality dropped substantially. Returning the product for good.
