After spending more time with the Amiron Wireless,
I've concluded one thing:
There is no Bluetooth headphone out there for me that has an exceptional sound that can fit on my head well (lol)
I can write a long review if any of you are interested, and possibly compare to the PX (although I'd be going from memory, I still remember the sound signature decently well).
When I first tried these headphones on, they sounded great. But again, now that I've had a decent amount of time with them, I can make some conclusions. I can still say that they're still good. Just not amazing.. They have a few aspects about them that I love, and which possibly may have swayed me so much in the beginning such as great craftsmanship, amazing comfort, and.. well, a good sound.
But, they don't sound phenomenal. In fact, they can fall short of the PX at times. In some songs, especially ones with a strong mid range presence, I feel like they aren't as clear. This is contrary to what I said previously, but it seems to vary from song to song. Some songs do sound great, while others seem to have something lacking to them.. Vocals sound great, but they can also sound a little more muffled than the PX, something that I didn't see when I first tried them on.
I stated that the Amiron Wireless was airier than the PX, which is true. I personally find the bass to bounce more and be livelier than what the PX had, it isn't as powerful and doesn't stick out as much as on the PXs. When listening to Lorde Royals, a song with deep sub bass, it just isn't as prominent as what my PXs had. It's not worse at all, it's just different. I prefer it on the Amiron Wireless. I like the highs a little more too. They're quite analytical, but pleasant to listen to.
While they do sound good anyways, they're definitely not perfect, and can lack some detail mainly in the mids on certain songs for some reason. This is evident in the vocals of some songs.
When listening to Medication by Damian Marley, a song that has a good amount of bass but also a great vocal benchmark, the clarity simply is not what the PX had. The vocals sound good, but a little muffled.
When listening to Accidentally in Love by Counting Crows (it's a Shrek song, yes. But it's very good), the instrumentals don't have the clarity and punch that the PXs had, and vocals and instrumentals seem to overlap near the middle and sound kind of messy. This is a song I really like, so I know it pretty well. It was just a more enjoyable experience on the PXs.
Other songs though, are better on the Amiron Wireless.
Fortress by Illenium sounds amazing - the bass is incredibly punchy and not overwhelming, the vocals sound amazing and smooth with great clarity. Just a great song on these headphones.
There are other songs that sound great on these, but others that the PX excels in.
As a last paragraph, I'd like to talk about their issues. They sound good while hooked up to a computer or wired to a phone, but in wireless mode there seems to be distortion at the low end with loud volumes. I know I said that it's not a big deal, but it really gets to you when you hear your headphones buzz on some bassy songs. With the MIY tuning, they get louder, but there can be a lot of distortion in the low end if you put it up high. To be honest, this is only a big issue with genres like hip-hop. Vocals will sound warbly on songs that have a lot of bass. Also, they're quiet, something that the PX are not.
Here's my personal conclusion:
They still sound great. In some songs, I feel like they're actually really great, but in others, I miss the PX. I can't quite put my finger on it, but some songs just have something missing with these headphones. They don't sound that bad, they just left me a little dissapointed. The low volume and distortion disappointed me as well, but other things like build and comfort make me glad I bought them.
If you're looking for a good pair of headphones that are very comfortable, you should try these out. In general, the audio quality is great with some shortfalls. My main issue with them is just the clarity and how they can sound a little muddled with the mids, but on certain songs I can swear that they're more pleasant to listen to than the PXs.
If you already have the PXs and feel like they're comfy, I'd say you could keep them. Both of these headphones sound great and have their own pros and cons, but you'd end up saving $300.
I don't have them side by side to do extremely analytical tests, but the only songs where I've tried comparing them are the ones that I am very familiar with and have listened to a lot on both headphones.
And as always, everything I say is my opinion. I'm not an audio pro, I just say what I hear and try to give a detailed explanation of their sound. I'm doing this comparison so you guys know what to expect, but my ears are still my own and what I've said is just what I feel about the sound. It's important to mention that with everything.
I'll be returning them and going for the DT1990's with an affordable DAC and amp. I feel like it'll be a good step into high-fi territory without spending much more than I've already spent on the Amirons.
