Thank you for the recommendation! I did some more research on this pair and they seem really solid for the money. Current price was pretty tough to resist, got a set for me and one for my wife, too.
What do you mean with spatial audio? Most of the time it's done by software simulation of HRTF, which means that you can do this on any headphones. Windows for example has a Dolby plugin that you can purchase. However, most games and songs are already mixed with "spatial audio" baked in, so you'd only be applying double spatialization to the audio.
I guess I just meant something a little more precise than just left and right for directions you can hear audio from. I didn't realize this was more of a software thing. I don't know a whole lot about audio tech.
Spatial audio is a confusing topic because of years of marketing. In the real world, directional audio works through the shape of your ear. When sound comes from a direction that's not directly inside your ear, it gets modified by the skin and bone, through frequencies being boosted and suppressed but also some reverb. This modification is different for different directions, and your brain can pick up these cues. Software can try to simulate this for headphones, by applying this processing in software, as long as you can "guess" the shape of someone's ear and then run a simulation of how sound interacts with it. There's some clever tricks for how to do this very quickly without having to execute physics code.
And logically this makes sense, there's only one measurement place in each ear, why would you need more than one sound stream going into each ear?
So looking for good "spatial audio" headphones is in my opinion a scam. You're better off just buying the best audio quality headphones you can without really paying attention to spatial audio.
Terms you might hear online are soundstage (how well you can separate instruments) and imaging (how well software/recorded positional cues are reenacted by the headphones). These two are acoustic qualities that might be important to you.
Bit late, but I'm using the Sennheiser HD 569 a lot for remote work. Decent sound quality, comfortable and an inline mic in a replaceable cable. Where I live they sit around 100 euros. Not sure about the dollar price
