Top critical review
Minimum volume is TOO LOUD. But good customer service.
March 10, 2019
Beginning with the cons:
The sound will cut out below a certain volume threshold, this threshold is much too high. The first day I had it it didn't really bother me much, but after the first time I charged it, it got louder for whatever reason. A first I thought whoever designed the circuit just left out a voltage regulator to give it an extra few minutes of battery life, rendering the volume proportional to the charge level. However, it stayed louder.
This probably wont be an issue for most users. It is intended to be used on speakers with independent volume (like in a car), not with headphones. But I use this almost exclusively for headphones since the sound jack in my phone is broken.
Another complaint, the last 10% of the battery life is useless. Cut an hour and a half off that 15 hour run time because it will beep at you every 30 seconds when the battery reaches this level. Granted, it is bad to deep cycle lithium batteries so you shouldn't run it totally dead every time, but it would be nice if that were possible without the obnoxious beeping.
I also find myself accidentally pushing the buttons while in my pocket sometimes.
It doesn't work with headphone buttons, but since it has its own, it's not a big deal.
Low latency, video sound doesn't seem out of sync.
Sound quality isn't much different than a wired connection.
Small and light.
Charges pretty quick.
By separating my phone from my headphones, the cable will wear significantly slower and I won't need to hassle with it when I take my phone out of my pocket.
Update: They sent me a different version for free which is great, but it was still too loud. The other version doesn't have an issue with an issue with accidental button presses but it has one set to share volume and skipping. Short press for skip, long for volume, which is completely backwards in my opinion but you'll get used to it
