Hello, thanks for your helpful response. I'm not sure about the DUNU Titan 1 because of its' shape. From experience it seems as if deep-insertion can give a better sound, but this one looks like it may not go in deep enough. And what are those vent holes on it?
For the RE-400 this seems nice, but I've not been a fan of the general Hifiman 'house sound' from their full size 'cans, except for the HE-6 which was phenomenal. By any chance would you be able to post which full size headphone the RE-400 sounds most similar to - Hifiman or any brand? Thanks, and I still hope LjokerL can jump in on this too
There are not many in this price range, and those you will find will be either super flat like ER-4 series, ortofons and Doppio or will be V shaped like Dn-1000 and XBA-H3. But there are a few you can consider.
I dont know if its available at your convenience or not but flare audio R2 is an awesome sounding earphone, another one will be Fidue A83, be careful of its shape though, best i can think of is FLC-8!! Even if its a bit over your budget, its worth it. I fancy owning one of this FLC-8 earphones myself.
Then i think if you enjoy some bass, you will like DN-2000 too. Not overly analytical.
I think Joker can shed more light on this.
