You can always find some little flaw in the sound of any headphone/IEM if you are really looking for it. In my opinion the IE600 is endgame and there is no real reason to waste time and money stressing about which more expensive IEM might sound 5% better. As good as the Airpods Pro 2 are I really don’t think they come come to the IE600, they are just good for tws and sound like $100 IEMS plus I can’t see tws ever outclassing flagship IEMS because of the cost of constantly developing better ANC and other features they will probably always be a step behind or at least cost more than similar priced IEMS

I use Amazon because I was able to pay for 12 months upfront for the cost of 9 months which meant it was cheaper than any other lossless streaming platform but I have been thinking I will try something else after the 12 months are up because the app is really buggy although the app does seem to have improved recently and I haven’t really had any problems with it for a couple of months now so I’m seeing how it goes but I will likely look into supporting a more ethical company that pays the artists more next time.

The user face and recommendations seem pretty good although it’s been a few years since I have tried any of the other streaming services so don’t know how they compare.

I find spinfit W1 tips seal better than any other tips I have tried and even improve the soundstage and bass a bit, you can get them from AliExpress. The B3 cable is supposed to be decent so there shouldn’t be a need to change that.

That is plenty good enough to drive the 800S well. Make sure to EQ the 800S as that will make more difference than a more expensive dac/amp.

The answer to this question should be obvious. The Arya is basically a one and done headphone. You don’t really need to worry about other headphones especially downgrading to a lower Hifiman when the Arya does everything better. I don’t understand why some people don’t do much research before purchasing expensive headphones.

I wouldn’t say they are good but they are better than beats.

560S is the best choice for gaming due to its slightly better wider soundstage but 6XX is better for listening to music due to the smoother sound.

I own the 560S and HD600 which is similar to 6XX and I haven’t used my 560S in months. The 600 is much more smooth and enjoyable sounding whereas the 560S is thin and a bit boring in comparison. It is well worth the upgrade in my opinion.

If you really need very strong ANC then no, otherwise yes you are stupid.

I prefer the 600 as it is slightly clearer sounding which is better for busy music like metal/punk but they both sound very similar and if you are going to use EQ there is basically no difference.

Just have some self control and think, they are just headphones there are more important things to spend your money on. The 6XX and Ananda is a good combination of two very different sounding headphones to have and anything more expensive is either a sidegrade or a slight upgrade that you will never think is worth the money.

Only a few days ago I was thinking a slightly warmer sounding HD800S with better bass would be a perfect headphone for me then these come along. $3k for headphones is way out of my budget though sadly.

I personally prefer the 600 and sent the 660S2 back. I just find the 600 to be a little bit clearer and smoother sounding but some people do prefer the 660S2. Value wise I think all the 600 series should be the same price.
