I once had a Philips SBC HC8850 was at an end. He cut all the time since I bought it, the sound was distorted short I was not happy.
What was my surprise when first using the RS180 !!!!!! The arms fell to me !!!!
The sound is clear, clean, distortion-free, CD quality, you can hear the matter. It is absolutely FABULOUS! No vibrations in the helmet even if the volume is loud! I love these headphones is superb. Lightweight, does not hurt the ears and no break in the middle as with my old helmet. I rediscovered my musical pieces and I hear them as if it was the first time so they sound perfect.
The buttons on the headset are a bit confusing at first but you get done quickly, and then the keys are fairly well defined and touch you come to find the key we're looking for.
5 stars without hesitation, I recommend it for those looking for quality both physical (helmet and bases are very beautiful) and sound quality!
Kind regards.
