I travel frequently, and these take the edge off of the constant in-flight noise, to the point that when I remove them to get up out of my seat, Im overwhelmed by the noise Ive been missing. Removed the original ones and replaced with this. I ordered size 5 I?m usually 5 and these fit great very comfortable take a couple weeks to get used to but after that . Installed 5 of these in the bike cage to allow the bikers a place to hang their wet gear. If youre looking to upgrade from the supplied tips for fit, stay-put, sound, or improved noise cancellation, I give these a strong recommend. Hopefully these last longer and maybe only have to replace once a year. Jai hésité à lacheter, car je trouvais le prix un peu élevé, mais je ne le regrette pas du tout. I triple checked my drivers and software. It certainly does NOT ?snap on?, nothing ?snap? about it. I love that the crosspieces that the shirts hang on can come off the vertical piece - it makes getting to the shirts on the bottom much easier.
