ZS5 Bluetooth Cable lasts for about 3 hours on 65% battery (distorts with anything higher, doesn't have the power to drive). Charging takes longer than I would imagine. Poorly shielded if you live in an area with a lot of RF (I live near a 50KW radio station), or live in an apartment (I have 200+ apartments competing for Bluetooth and WiFi). Works fine on my phone but when I'm in an area with a lot of RF or WiFi, it will skip. I think some of this may be due to the Pixel XL knowingly having poor bluetooth connectivity.
Audio quality is much better than I expected. Not much to complain about. It's Bluetooth.
Latency and range are much better on my Laptop. I can walk anywhere in my apartment and have no issues with range. Latency on my phone sometimes is a second or two out of sync, but youtube will try to fix it often. Latency on my laptop is probably 50-100ms and you barely notice it when people are talking.
Not bad for $10 same day shipping on Amazon.
