Just plug ... and marvel at the clear and distinct understanding! I use the small miracles every day professionally many hours and never want to miss it! For work in the home office area or for Telco's (even in larger rooms) a clear recommendation. My headset remains are usually. Even my interlocutors gave me good marks for the good communication. The compactness and the small bag, it is also on the road always. 5 stars for a professional part. The price is absolutely justified.
