Sennheiser XSW-D Instrument TX

It is as simple as it seems but it works flawlessly as you would expect from a Sennheiser product. It delivers what it promises and makes your life absolutely simpler: you plug the the dongles, you pair them (if needed, normally the first time) and then you just use them, as simple as that. I have used them already both indoors and outdoors including open air music festival stages (mid size, we are not speaking of Rammstein setup here...) with plenty of other wireless systems around and absolutely no issue. You don't have to worry about channels, about anything and the quality of the sound is excellent without funky stuff happening at any time. Battery life as for now is really long... I have used it in real life situation for around 3h without getting to critical levels which is more than I normally need. Time will tell if these batteries keep delivering. All in all, worth every penny I would say.

It simplifies things quite a bit. Since there's no input trim, you quickly have to manage the gain. However, the sound quality is good. It seems to be more precise (in sound and quality) than the competition, but it's also a bit more expensive.
