Summary: I bought these for my wife to use in the gym, on the basis of these reviews and from the fact the looping system would assist in keeping the cords neat and untangled and help to prevent the buds from being tugged away.
Summary: Good points: They are very comfortable to wear. They look the part. Bad points: I normally used Sennheisser CX300 but changed to these recently due to poor build quality of the Sennheisers. The sound quality of the Panasonics is very poor and is not nearly as good as the Sennheisers.
Summary: I loved these when I first got them. The sound was great, they were comfortable. I could use them with all my devices. But they didn't even last a year. The sound on one side has gone quiet so it sounds really weird now and if listening in stereo some noises/lyrics can't be heard at all.
