Amateur singer and novice in terms of settings, I decided to invest in a wireless system but the desired HF microphone was out of stock (and a bit expensive) and loving my wired Sennheiser e845, I temporarily opted for the XS Wireless Digital system from Sennheiser as well. Regarding the product, nothing to complain about... it's very practical and easy to use (charge, pair, and plug into any XLR microphone and you're good to go)... The sound transmission is really very good despite a disturbing white noise if there is no music. But for digital, you can't complain. I have the same sound as wired. It's also small, so easily portable in the microphone case. And the advantage of running on a rechargeable battery with any USB-C cable means I can totally sing in the middle of the street by connecting the system to my Bose S1 Pro, which also runs on battery since I can use the system without electricity for a few hours. Of course, it certainly doesn't match a good HF microphone system but it has the advantage of being versatile and can adapt to all your wired microphones, so it really helps out and on top of that, you can really sing anywhere since unlike a real HF system you won't need electricity. So it's good to have anyway in addition to an HF microphone system... I took off one star because it seems that either the product I received was not new (maybe a return?) or had been opened, which I find unacceptable since I paid the price of a new one because the box was no longer sealed and the packaging bags were missing. The USB cable was unrolled and the bag already opened. Fortunately, the product works!

Excellent rendering, impeccable quality, ease of use. Note that it is not usable with microphones requiring phantom power.

Lasts about 5 to 5.30 hours of autonomy (with two repetitions of 3.3H). I complete it with the microphone for flute (reference ADX10-FLP) and the sound is as if we were connected with a real XLR cable, to recharge it, count about 2H, with any type C cable.
