I concur. I have dozens of these. Enough to last long after they finally sell out.
You can save even more by searching for the 20% off coupon code. And then use the free shipping minimum on top of that. Sure, you have to buy a bunch of them, but they are worth every penny (and cheap compared to Spiral Dots as you mentioned). I’ve gone in with friends and even other HeadFi members on orders, so we all benefit from the free shipping minimums.
They are my favorite wide bore tip.
Also, the 2 pairs for $1 deal has been sold out in the Medium size forever. If you need Mediums, your only other option is the SML packs for $1.50 each. I’m those cases, I’ve been able to recoup the extra costs by selling or gifting the sizes I don’t use (so S and L in my case).
