I completely agree. Try them out for 30 days and return if you don't like.
I'm sure there's individual differences in how they fit into ears and the potential helmet irritation I am experiencing. That said, despite my irritation, I have not ridden without them since I got them - they make that much of a difference in cancelling out the wind noise.
I have found that in addition to being really useful on the bike, they are a fun party trick - have people try them on, then hit the 'on' button, and watch their reaction. Very cool technology.
As I said before, easily the best $150 I have spent on my bike, ever.
So here is my little review.
Ordered and they arrived in less than a week which was a pleasant surprise.
Appeared to be in decent shape, the black box was a little grubby and had some dirt stuck in the recessed panels. The part that goes in your ear, thankfully , looked new.
As others have mentioned, the sense of awe when you turn them on is stunning.
Certainly needs a little practice putting a helmet on (in my case a modular) so as not to knock the earbuds out of alignment.
These things absolutely cut wind noise, what feels like 90%. Heck you can hardly even hear the bike running.
But for me they had to go back for two reasons
1) I like the wind in my face (unless its raining) so I generally ride with bike screen in its lowest position and my visor open. At speed this just causes too much popping for me. After a while it gets annoying.
2) They cause too much discomfort after 2-3 hours of use under a helmet. For me, they stick out too much and really began to hurt at hour 4 and 5. Next morning as soon as I put them in, the discomfort started. I did stick with them for two full days of riding (7 hours on day one, around 10 on day two) to see if I would get used to them but ultimately I decided to return them.
If I only ever rode short distances then it would be a no brainer and I certainly recommend trying them out to see if they suit you.
I have returned mine now so it will be interesting to see how smoothly the return process goes.
