SennheiserXSW-D Instrument Transmitter

I have a total of four of these, and one of the four simply won't hold a charge. The other three last through an hour-and-a-half gig without the battery ever getting off solid green, but the fourth barely lasts an hour before it angrily flashes red at me. I have a temporary workaround in place - plugging it in while in use, which does not impact performance - but that third letter stands for "wireless" and plugging it in kind of (partially) defeats the purpose.But in terms of performance, these can't be beat. There's no noticeable latency, the sound quality is outstanding, and the range is excellent - just what I'd expect from Sennheiser. My hope is that the battery issue is an outlier, and I'll be exchanging that specific unit to make sure. I'll update this review with those results.

Poor battery life, so so sound quality. It’s just there aren’t any good options out there that don’t require a belt pack. It’s at best ok.

Item was exactly as advertised and send very quickly
