They include every size that could possibly be needed to ensure a cozy fit

The fit out of the box was perfect and then the sound...easily the best reproduction I've heard with this type of headphone.

Phenomenal range and great comfort (plenty of spare squishies to find the perfect fit)

Although the fit is spectacular (after trying a few of the different included attachments, I was able to find one that is the absolutely MOST comfortable pair of ear-buds I've ever worn), the sound isn't all that great

Great fit

I own "Anker SoundBuds Sport IE20" for almost two years now (still going strong), but I prefer the new one thanks to the better fit and seal

Just to note, I have been using Plantronics Backbeat FIT for over a year and those were a great fit, but terrible sound quality

It comes with enough ear tips to get the right fit which is important for noise isolation

Anker sent me a replacement and again, great fit and sound

This allows for the most flexibility in getting a nice tight fit for use while working out

With a simple pull, I'm able to create a tangle-free tight fit, which greatly reduces the annoying sound as the wire contacts clothes

Great fit and

I did need to okay with the different sized earpiece accessories till I got the right fit for my ears

Perfect fit

Most earbud headphones seem to fall out of my ear or come with oddly shaped buds, but these fit perfectly

It sits MUCH more comfortably in your ear, the little controller thing (lol) allows you do much more and with all the pieces it comes with to customoze the right fit, no matter your ears' shape you will definitely find the combination that sits perfectly insode your ear

Very good sound quality, and have a comfortable fit

These headphones have great sound, good fit, great range

I just received mine today, which I know isn't enough time to post an adequate review, but I just wanted to say that right out of the box they have a great fit and great sound quality for the price

It just tells me that the B&W PX's are not as impressive as I
