Which is why i would always use dre beats large ear tips on other earbud or tws for their seal. Sednaearfit xelastec ear tips just blows the competition away. They fit in nearly every case without having to take them off.

They sound brighter. Bass, clarity and instrument separation are excellent. Noise cancellation finally works like all the reviews promise.

A wonderful tip option. Couple things to be careful about. I have dozens of tips and these are the go to tips out of them all.

The azla tips grip the iem mount tube well and do not come off easily when inserting or removing. They work best on iems that have medium to long nozzles. A little tight on my starfields nozzle, but in a good/secure way.

These stick in your ears like they were glued in and they are comfortable. Because they do morph to your ear shape. They have a tacky quality without being sticky.

In trying to get a better seal (forcing these to sound better) by sticking them in further, they come off the ear tip. They're pretty pricey for what you get, and there's no single-pair pack.
