So, I'm currently using a wireless Pioneer headphones, not sure of what the model is because I got it as a gift a year ago, and I have been wanting to upgrade to a better headphones and I need help to choose.
I'm going to use this headphone to listen to music, so sound quality is what I'm looking for the most, I listen to all genres of music, but the main ones being rock and jazz.
As for budget, the highest I can splirge on a pair of headphones is probably $400?
Here are some headphones that peak my interest as I have heard them being spoken as good headphones, though feel free to recommend me others:
1. Shure Aonic 50, I quite like the idea of a wireless headphone but I've heard that the sound quality does not compare to wired headphone so this might not be the best choice.
2. HiFiMAN Sundara, I've read reviews and this seems as everyone's go-to headphone.
3. Sennheiser HD6XX, again, this seems like the go-to Sennheiser headphone, or maybe the HD600.
Do note that I live in Indonesia so it's a bit hard to get your hands on some headphones. Thank you for your attention and thank you even more for your help.
You won't go wrong with the Sundara at $300 US since it does almost everything well. You mention Senn/Drop HD6xx, so if Drop ships to Indonesia, also look at Dan Clark Audio / Drop Aeon closed X to be on sale for $379 (they do so off and on); pretty similar to Sundara sound when both headphones are equalized to a common target FR curve, but the Closed X is a modest notch better on resolution, separation, tight/clean bass, build quality. (I own both and have compared them extensively.)
I also own HD6xx and mids are nice, but the old design is kind of light on bass; and the bass it has does have plenty of bass distortion that just gets a bit worse if you equalize back in some of the missing bass. HD6xx doesn't hold up next to Closed X and Sundara on this score. Closed X has lots of clean bass, and you may want equalize the Sundara to add some back in; it has less bass out of the box, but unlike the HD6xx it handles bass equalization very well. To my ears, the Sundara has a bit more bass distortion but it lends a nice, euphonic resonance to bass guitar on some music; on some other music I like the Closed X for its very clean, undistorted, deep bass. (Some people have to make sure of a close fit of the Closed X to get the full benefit of their extended bass response; I have absolutely no problem with that myself, but I believe some others may have to be careful with a tight seal of their earpads.)
Note Sundara is open-back (not acoustically sealed off from environment), while Closed X is closed-back (acoustically sealed off). As a general rule, open-back headphones may sound more "open" but have less bass, and noise from env't may interfere; closed-back headphones are very quiet, and this may help in hearing fine details, and they may have better bass out-of-box; but may also be a bit more "damped", meaning less reverberant. (In the specific cases of the Sundara and Closed X, they sound more alike to me than not on this score but YMMV.)
Without equalization, both the Closed X and Sundara are already pretty close to the Harman FR curve, which is a good place for most people to start from in identifying the sound they like. As many others have said, doing a little with equalization adds more sound quality than spending a lot more $$ on hardware. The process also educates your ear as a music listener. (You can get started with equalization for free. There's plenty of advice around on how to get started. Doing it really well is a bit of an art, but getting to 2d base isn't hard, and there is plenty of guidance on ASR on how to get at least to third base with any given headphone reviewed here.)
[EDIT: PS you need a decent USB dongle or desktop amp to drive the Closed X. Lots of desktop units will work, but for a dongle, I use the nice Hidizs S9 Pro's balanced outputs and it works really well, whereas many other dongles might be underpowered. But balanced cables plus dongle would add ~$180 to the bill. So sorry if I pushed beyond your budget without thinking it through. That said, you might want at least a good dongle even for the Sundara, to get the most out of it, especially if you equalize and need some headroom. Sundara + dongle (balanced cable not neceessary) will run about $420 or so. If you listen mostly from your phone, not your PC, then substitute Qdelix 5k for the Hidizs, and you can equalize right from your phone (use same budget)].
