Stax headphones have some of the most unique designs around, featuring a rectangular cup for their SR-L700MK2 model which comes in at $1,569 USD. Although, this model isn’t Stax’s most expensive. That title belongs to the new flagship model, SR-009S, with a cost of $4,325 USD.
The flagship model includes a finishing and etching process that lowers the amount of air interference, therefore increasing sound quality. Additionally, the gold plated cups of the flagship model reduces electric resistance, giving you the purest of sound wavelengths.
