However, this was the only criticism of the Bluetooth I could find. I noticed a slight hesitation between pausing music and replay - more so than with other speakers I have tested. It has a frequency response of 20-Hz to 20Khz and sounds are clear across a wide range of bass and treble. The sound is good across a range of frequencies. This is a useful feature - especially when you are out and about and unable to get to the phone to unlock it. The circular multifunction button will also redial the last number dialled - even when the phone is locked. I usually set the levels as the start of operation and do not have to change the volume often during use. I found this a challenge as I could not remember which button was which.
