Its been too long since I last bought these tips... it wasn't until I changed them and found how much better the ear plugs worked that I remembered their value :-)

Great, but don't assume sizing from previous model

I recently bought new Isolates because I could no longer get foams for my older Isolates. I've been using them for about 12 years, and they're great. One thing to note: the sizing is completely different. I thought I would be 'Small', because I've been using Small earfoams for all these years, and so I ordered a bunch of extra ear foams in Small. But the new ones are entirely different - 'Small' is tiny, and 'Medium' is huge! I've found that the Medium does work for me, despite being so big, and so I'm really happy with these. Just take your time and check what actually works for your ears!

I started using the Isolate at work because ear defenders were awkward for everyday use. These were perfect so I bought more ear buds so I can continue to use the Isolates.
