Sennheiser - HD 620S

If you do try the HD620 based on the other comment, make sure you have a return policy where you buy them from. The headphone is highly fit dependent. They wouldn't even sit straight on my head and kept getting off my head because of the insane clamp. And I use HD660s/600 as my daily drivers (when I'm not using the Koss KPH40), so I'm not new to clamp. Plus I found them to be a bit boxy in sound. I'm still waiting for a good closedback from Sennheiser for monitoring, I was hoping HDB630 would be it, but the latency due to the in-house dac makes it a no go, hopefully they make a passive closedback with the HDB630 sound as well.

I recently bought the HD620s, probably the most detailed closed backs I've ever used!

You can just look at a headphones impedance. Sensitivity matters just as much. The HD620S is not hard to drive for a DAP.

Momentum 4 are great, don't get me wrong. It doesn't touch my list because I don't have any need for wireless headphones. If you want/need a wireless headphone, momentum 4 is by all mean a great pick. If you need isolation and don't mind wired, hd620s is another fine choice. In the end, it's about your wants and needs. Our life differs and so will our choices

**Sennheiser HD 620S** \- Nice relaxed Sennheiser sound but with more bass than 6-series open backs, has that beautiful Sennheiser midrange, slight bit of treble weirdness, nothing too crazy and quite easy to correct, lacking a smidge of bass impact, nothing a bit of EQ can't rectify. Sound stage was quite good for a closed back, as was imaging, exceeded my expectations in this area. Respond to EQ fairly well, they do distort fairly quick if you feed them too much bass without enough negative gain. Absolutely fantastic build quality, these things are built like tanks, lots of clamp but rapidly loosening up the more I use them. Only negative in the build department is the stock cable kinda sucks. It's thin and holds it's shape too much. 150 Ohm impedance pairs nicely with a tube amp, love how they sound on the Valhalla 2 in high gain mode. 8.5/10 would recommend. **EQ settings:** \-7.8dB preamp gain | (1) Peak Filter 24Hz @ +6.0dB Q factor 0.71 | (2) Peak Filter 64Hz @ + 1.5dB Q factor 0.71 | (3) Peak Filter 118Hz @ -3.0dB Q factor 6.00 | (4) Peak Filter 238Hz @ + 3.0dB Q factor 5.00 **Sony MDR-MV1 -** Wow, how much bass can an open back have? These have a ton of bass impact and slam, and nice deep bass that's also tight. Listening to The Weeknd on these was a blast. Midrange was quite pleasant as well, treble definitely on the brighter side of neutral, just a bit peaky for my taste, but boy can these reveal some fine detail. Super low impedance so best to drive these from a source with very low output impedance, these do not pair well with an OTL tube amp at all, even on low gain. These EQ really well, generally require less EQ to get them where I like compared with the 620S (I do love me some bass). Comfort? PHENOMENAL. 11/10, super lightweight, aluminum ear cups with nice plastics, headband is comfy and spreads the weight, pads are excellent, my ears don't get hot in these at all. Might be the most comfortable pair of headphones I own, maybe the most comfy I've ever worn! 9.5/10, highly recommended! **EQ settings:** \-3.3dB preamp gain | (1) Peak Filter 23Hz @ +2.8dB Q factor 1.00 | (2) Peak Filter 6000Hz @ - 2.2dB Q factor 3.00 | (3) Peak Filter 7000Hz @ -1.5dB Q factor 3.00 | (4) Peak Filter 9450Hz @ -3.0dB Q factor 6.00 I've really enjoyed both of these, both had me grinning from ear to ear listening to different tracks. I honestly wasn't expecting to like both, and figured I'd surely be returning one or the other. Guess it's time to offload some less used headphones to subsidize these haha

HD620S is my Roman Empire. Maybe it’s just because it was the first headphone that really hit “audiophile sound” home for me, maybe it’s because it’s one of the few where it feels built for my huge head and gigantic sticking out ears, but I just love em. The sound has problems, but not unfixable problems.

Sennheiser HD620S are the most comfortable closed backs I’ve ever tried 

From least to most favorite: Audio-Technica ATH-M50X - well-built, cohesive imaging, but some of the most unnatural-sounding headphones I've heard, having a huge hole in the lower mids, mud-fest in the bass, and harsh peaky treble Audio-Technica ATH-M60X - well-built, surprisingly spacious for how small they are, but still a hole in the lower mids and shouty ear gain, plus they're on-ear and therefore uncomfortable Audio-Technica ATH-M40X - well-built, decent all-rounder, but still lacks the lower mids and mid-bass is too boomy, plus the treble is a bit sibilant Sennheiser HD280 PRO - great isolation, large pads, cohesive imaging, but too much sub-bass giving me a headache, too dull yet grainy, plus the cable is microphonic, heavy, stiff, and non-detachable AKG K361 - the most tonally balanced overall, but not very impressive technically, having kind of a tinny timbre with metallic treble, mediocre imaging, and some of the worst build and comfort with a huge design flaw - earpads have a lot of compression with pressure affecting the FR, creating constant channel imbalance, so you have to be perfectly still while using them AKG K371 - the same but more natural timbre for the sacrifice of warmer and muddier tuning Sennheiser HD620S - nice build, comfort, and isolation, good clarity, but unpleasant, cold, harsh, focused, claustrophobic, fatiguing tuning with wonky low-end Adam H200 - nice build, comfort, and isolation, surprisingly spacious, good bass quality, but too shouty FiiO FT1 - the best all-rounder, most casual, most comfortable, solid tonal balance, spatial qualities, and bass quality, but too much bass and too peaky unrefined treble, making them sound fatiguing Beyerdynamic DT770 PRO 250Ω - the best clarity, sounding almost like an open-back, great all-rounder, great low-end and midrange, decent spatial qualities, decently comfortable, but too sibilant, making them unsuitable for a certain kind of music NOTE: I also had the 80 and 32Ω versions of the DT770 but didn't like them as much

Your parents are loud enough that you need ANC? Or do you just think you need ANC? ANC in a home environment often isn't the best as the pressure effect it creates can be a bit unpleasant (why deal with it outside of environments where it's needed) plus that level of isolation isn't always a good thing in a home environment (you may not be able to hear someone calling you). At that price point, if you absolutely need ANC, I'd probably say the 1-generation-old Sony WH-1000XM5. If you realize you don't actually need ANC, then I'd get something like a Sennheiser HD 620S and eventually get a headphone amp when your budget allows.

There is no best, it's subjective. Though I would generally prefer open-backs over closed backs, especially when you're just using them in your chair and not a noisy environment. "Audiophile grade" is also not a clearly defined term. There are a lot of good options available for under 1000$, I would recommend ordering a few different pairs and comparing them. Like, as far as open-backs are concerned, get a Hifiman Arya, Sennheiser HD 6XX and maybe a Beyerdynamic DT1990 (note that there's two versions, you can get some great deals on the older MK1 but it has a very spicy treble). If you really need/want something closed, your options will be more limited, you could try a Senny HD620 and Beyer DT1770. Personally, I think the AKG K702 (open) for 180 USD is an incredible deal, but some don't like the mid-heavy sound. And there's no doubt there are better headphones to be had for three or four times the price, but they won't really sound three of four times better, and whether it's worth it spending so much is up to you.

Everything here. Or even the HD620s if you want some good sounding closed backs.
