I think most of headfiers know the comply foam tips. I have been using it since I started to use some IEMs, it offers great comfort and isolation which is most important aspect for IEM.
By starting this thread, I hope comply fans will write reviews and experience about the different series, such as TX series VS T series or P series, the newest TS series. From my personal perspective，the long P series is not as comfortable as TX and T because the backbone will make too much contact with the inner ear and for those who don't have much earwax, the TX is definitely not necessary.
Lastly, I really appreciate comply corporation for providing the most fantasitc IEM accessory to us!
