When hearing a song, with your Woojer on, you might sometimes feel that Woojer plays a little offbeat. However, that isn't true. Woojer only shows you the low-frequency bass content that is in the track - we don't add or take away anything from the content. If the bass is late in the track, on purpose, Woojer will accurately show you this.

To test that, Please play this video, when your Woojer is connected via a 3.5mm or a USB-C cable, to eliminate any wireless latency effect. You should hear a sound on every beat, but only one of the 4 sounds will be felt. 

Please refer to this article for a thorough explanation: Understanding and Handling Latency (lag)
