My vest 4 experience.

Having used the Vest 2, I upgraded to the Vest 4 hoping for improved battery life and haptics. I primarily use the Woojer Vest for music in VR raves and charged it to 100%. The first problem I encountered was the Vest getting extremely hot – a stark contrast to the Vest 2. This discomfort forced me to reduce the intensity. With the Vest 2, I can use full intensity without overheating.

Another issue was battery life. After just 1:45 hours, the battery was completely drained. In comparison, the Vest 2 lasts 3-4 hours under similar conditions.

While I use the Vest 2 wired and the Vest 4 with two-way Bluetooth, this might contribute to the battery drain. However, I’ve read that the Vest 4 should last 4-6 hours. Given the heat and battery problems, I’m considering returning the Vest 4. The Vest 2 currently feels better suited to my needs.
