ISOtunes Trilogy™ Foam Replacement Eartips for ISOtunes PRO, Xtra, Wired (5 Pair Pack) (Large, Blue)

More durable than other brands. Daily use for years. All day comfort in all conditions.

It doesn’t twist into clarity alofts

Only gave 2 stars because in ear these tips work really well. But the downfall, and a major downfall at that, is that i have to take the tips off just to be able to charge my isotunes earbuds. They WILL NOT fit in the charging case with the tips on at all. I thought they were going to be replacement tips the same size as what came with the original product, but theyre more than double the size

I bought these hoping they work for my Klein Tools earbuds because I couldn’t find any other foam replacements that fit on their small stem. Although ISO Tunes screw on and Klein tools doesn’t, these replacements can be worked onto the stem and they retain well. The Large foam tips don’t fully allow the earbuds to seat in their holder. All I did was snip off the end a bit until they did because I didn’t want to go through the return process. Hope this helps others who love their earbuds but couldn’t find foam repacements.

The tips that came with my isotunes pro were far more worn than I thought; putting on a new pair improved comfort, noise reduction, and stay-in-place-ability tenfold. No more jamming them further into my ears every 10 minutes, and I was able to reduce the volume setting by two increments. I do wish they were cheaper and lasted longer, but they're within reason. I use the isotunes around 10 hours a week, and the first pair lasted about 3 months before losing their ability to seal well.
