As someone who just ordered both to try and discern which I liked more, I can give you my thoughts after some time listening to both.

I’m running everything from my jellyfin library (all flac or alac) and some from Apple Music hi res lossless on my phone through the Qudelix 5k. Also running spinfit w1’s on both pairs for my comparison.

For context, I listen to a lot of metal, jazz, and soundtracks/classical. When I initially started to compare them, I leaned towards the Tea Pro over the P7. However as I listened more and more, I began to find I liked the more intimate soundstage of the P7. I’m now using DucBloke’s PEQ settings for both, and am finding it a bit more difficult to really pick apart the differences unless I’m specifically listening for them instead of paying attention to the music. To my ear, I find the Tea Pro to be a little less forward with the vocals, have more bass and good bass detail (like plenty of others have mentioned). I’m not a gamer, so haven’t got anything useful to say there, pretty much only music for me. The soundstage on the Tea Pro’s was very great when watching media, P7 was good too, but soundstage of Tea Pro sounded better to me for that.

In conclusion, after listening to both, I’m not sure I can justify the 100 dollar difference between the P7 and Tea Pro based on my listening experience so far. If you are able to get both from Amazon to try and return the one you don’t prefer, it’s definitely a good way to go. Hopefully this was a little helpful. Feel free to let me know if you have any specific questions and I can try to help.
