IMHO I think the BLON BL-03 is slightly below average in isolation compared to my other IEMs. For comparisons' sake, I do have a fan in my room and when I sit a meter away from the fan stream, I get the sound of wind whirling in my ears with the BLON. I've tried a few different silicone tips and this whirling sound still gets thru. Not sure if foam tips will help cause the foams technically will expand and block the ear canal, but I have a feeling foam might dull the treble, which is already pretty laid back in the BLON. I have a feeling it will not be suitable for motorcyling at high speed with wind in your ears, but worth a try first since u got it on order.
Yes, the isolation is probably below average with Blon 03. But the idea that foams dull treble and highs is a myth. People think that because they think that what they're made of will somehow deaden that aspect...but I've never found it to be the case. They may thicken the general tone, but that doesn't mean the treble is affected. Also, I think Blon treble is pretty present, as I mentioned before - and gives the music some air. It's not Tin T2 present (which I think is a bit too much), or tizzy like V80 can be...it's just very very decent. And I agree, I wouldn't wear them for motorcycling.
