Headphones

In second hand he's just around 40 or 50 bucks and often in good condition. Just wash and good to go.

Also, with the difference of price, you can buy a TRRS jack to connect to your DAC for exemple (Shanling Up4 2022 that's nice&cheap or the Fiio BTR5) in 2.5/4.4mm

Or you can buy the 560s in second hand for around or less than 100 bucks, and they're even better.

At any rate, this one seems close to the 598 that I have, it is really nice! The bass and sub bass is not loud, but they have a really good definition. Like, a "line" of bass guitar, or, not sure of the English for that, a "slap" on a bass, and globally the "attack" on guitars is really nice on the 598/599SE.

They're less well balanced than the HD 600/650 that I tried (or might have been the 660S 🤔), but you have a really better definition in bass and sub bass. (overall the 600 series is better, but for modern rock, punk, metal, pop-rock/poppunk and "indie rock", 599 SE is better, IMO)

So, a little EQ (wavelet on Android) and it's a formidable platform for a less than 100 bucks headphone. Movies and series with a nice source (dac, good soundcard, etc) are really good experiences, Dolby Atmos helps too, but isn't necessary.

Didn't have time to gaming since I own it, but no doubt it's a really nice headphone. However, because it's totally open, you'll need to have a quiet PC/console. (like, I don't use them for a movie if I'm not alone in the house, and if people talks even in another room, I push the volume up) (also, the HD 600/650 have weird stuff/artifacts in spatialisation, 598/599SE/560S don't, they're fine for gaming)

So, I recommend it to you, but you could save some bucks with people solding their stuff after the black friday/Christmas and get it for cheaper, or a get 560s for the same price.
