Drop has some steep audiophile markdowns as of June 17, 2021. Many of these are older products with mixed reviews, but the Elex is at $600 while the HD58X and HE4XX are both $160. Various IEMs are marked down by 50% or 75% – but still may not be worth it.
I bought the Ether CX from DROP at $750 a while back. It’s $800 now. It’s a good headphone.
