I've owned like 4 of these in my lifetime, it should be fair that I'd be the one giving it a price update.

After selling this for 2 Buds pure a few times(My own sales are too old to use tho), I'm fairly disappointed with the result.

Two sales at 1.1-1.2, ALOT of sales at 1.3-1.4, one sale at 1.5, three sales at 1.6 and three at 1.7-1.9. It's clear that sales happen above 1.3-1.4, however 1.3-1.4 dominates in the sales area. Going to play safe with a range of 1.3-1.6.

Additional Proof/Counter-Proof/Constructive Criticism/Feedback is always appreciated.
