Bought these for work hoping I would have headphones that fold in and out with great difficulty. First impressions were that the headphones were quite comfortable and the sound was decent, but the retractable mechanism was heavy enough to make putting the headphones on uncomfortable. This isn't an issue if you're at a desk or have other weight support, but I wouldn't recommend it if you're using it for a jog or similar. The usefulness of the headphones is that after about a week of use, the component holding the retractor in the extended position broke, so the spring will constantly try to reel the cord. The cable did not remain stretched and the spring provided additional tension on the headphone. It effectively renders everything useless.
