Bests & Worsts Reviews from Amazon

I have gone through two iJoy Logo headphone sets. This ISO version seems to have fixed some major and minor issues. The following are improvements i've seen: Both Logo headsets broke at the folding hinge a few months after purchase. This ISO model seems to be much more robust, using metal reinforcement over the plastic. The improved Bluetooth chipset starts up and syncs with my devices very quickly. I have not had to un-pair and re-pair as i did with the Logos. There are no more "voice alerts", just simple tones to indicate power on, power off, sync, battery, etc. I can actually have phone conversations with this model. Nobody could hear my voice with the previous model. They have removed the FM radio, and SD card mp3 player capabilities. I see this as an improvement, since it greatly simplifies the buttons down to 3. The slider power switch has been removed, and is now part of the 3 button pad. This new design is sleek and elegant looking. The padding is very comfortable and doesn't seem to get as warm. 5/5 Would Recommend. Great product for the price. Edit: It has been way more than a year since this review was posted. I just sat on them in my truck seat. They are fine. Still working great. Batteries last a long time. Still recommend 10/10.
