I bought the Sundaras for gaming, and strictly for gaming, but that's all they're alright with. I play a game called Squad where I listen to 8 voices at the same time and need to listen to the direction of gunshots, vehicle noises (identify specific vehicle types by engine) at the same time. So that's where the Sundaras came in.
But the Sundaras are too heavy as a daily driver, and they're a little too lean for me.
As for music the Sundaras were actually quite a disappointment, they're too lean, not enough bass to groove with, a treble end that's a little too harsh, and the mids are peaky without rising in the right places. My favorite overall headgear so far is the Sony WF1000XM4, the Sennheiser HD600 as a close second. When it comes to detail retrieval, I believe a natural frequency response is the best way, as I can pick and choose what I want to listen to. Sundaras just tried to shove detail into my ears, accompany that with the harsh lower treble peak that didn't sit right with me, it's not very enjoyable to listen to for music. I much prefer Sennheiser HD600's way of presenting music; smooth, and detailed when it counts.
Oh wait sorry, forgot this was the DT900 Pro X thread.
I'm hoping the DT 900 Pro X will be my savior, I have a pair of them coming in tomorrow. The treble reduction is what I've been waiting for out of a Beyerdynamic. The treble peak seems to align with my 9 year old, Audio Technica A900X, so I have a feeling I'll be relatively enjoying the DT 900 Pro X almost the same amount. I also intend to buy 2 extra sets of earpads for the DT 900 Pro X. I'm not going to lie, the whole covid thing made me rethink about personal hygiene when it comes to headphones. Recently I've been hand-washing my Sundara and HD600 earpads once a month, putting them next to a USB fan overnight and they'll be ready to use for the next upcoming month. So regarding that, the
DT 900 earpads can be had for $27 (pre-tax/shipping) which is way better than what I paid for Sundara Earpads.
After a few months of doing my research I'll be pulling the trigger on my first Beyerdynamics to replace my Hifimans, crossing my fingers I like the DT900 Pro X's and that I don't have to return them. I'm already planning to sell my Sundaras lol.
