Sennheiser XSW-D Portable ENG Set

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.

Pro:
GREAT sound
very good wireless performance

Cons:
Very uncomfortable on/off foil switch method
You have to hold the switch way to long for it to go off.
The hinged guitar side should be longer to allow a 90 degree setting if guitar jack is slighly recessed: Telecaster style.
