I use it for 1 year and no problem since scne.
This is a good micro versatile because there are 1280 of Frequencies available.
Before I had a HF Shure Sm 58 or I had a problem with his only available frquence I sold.
The Shure is much less clear for the voice that the Sennheiser.
What's more, I'll sell it to buy myself a cable version but because I have over the usefulness by doing more scne.
Trs good choice qualitprix report.
