Massdrop HE4XX Review 

Bet you didn't expect to see me here. This is only the beginning if you like Harman bass EQ'd in with 100% extension. Wait until you try an LCD2 lol. Also, very very technical review for a new reviewer, you've clearly done your research and maybe, just maybe, seen a couple of my videos, hah

the fact that you used Circa as a reference makes me want to get them. Circa has been my favorite band for 20 years...

I've been researching these headphones for a while , I finally ordered a pair the other day. I wish I stumbled across this review first, it has all the info I needed in one video.

Late to game. But ordered mine based on your review. I think they should compliment the HD58X, and DT900 pro X for a different type of sound. Running them all off a schiit magni heresy modi 3 stack. Definitely excited. Great review! Subbed.

I received my HE4xx a few days ago. I agree with your enthusiasm about the lows and other aspects. furthermore I've been testing those nice HPs in balanced conf. using a double 3,5mm mono>2,5mm balanced stereo cable I previously bought in the US, which I spent additional 45$ for. My device that I used for testing is the M11 from FiiO (nice gear, btw) BUT.... after an appropriate period of time listening music through these HPs I've put my AT MSR7b on and....they are superior in every aspect (in balanced configuration, using the AT cable Included in the price of 209€) when compared to the HE4xx, except for the very low range, where the HE4xx are a bit more extended. however, the MSR7b are at least 15 db more efficient, which is not an inconsiderable issue. to be clear, I like the HE4xx very much, though... It's just that IMHO the MSR7b are the BEST HPs under 250€ and I mean including the HD6xx, 58x and so on.... I'm seriously asking why ALL the most popular and experienced testers I know (including you, that I greatly estimate) have not reviewed them yet. Hope you have an opportunity to test those wonderful HPs. ciao.

I put ZMF Ori lambskin pads on mine and the bass got better. Not the cheapest mod though. I still pull them out on occasion but my Aeolus are getting most of my attention lately.

Already have a HD58X, and although i love how clear it is, I feel like they're a bit too intimate and vocals are too close to my head if that makes sense. Been thinking of trying these for the wider sound stage

Just came across your headphone reviews. Very good reviews. You seem to be trying for objectivity. You seem to really like the Senn hd650/6xx. They're my latest headphone purchase and I'm trying to get used to thier sound. I find them fairly dark and warm. I have other warm headphones but they have more treble than the hd6xx. I do find them narrower and more intimate as well. The midrange is very smooth but I find the upper bass elevation and the beginning of the lower midrange to be slightly more dominant. I do enjoy listening to them, though. Very smooth and relaxing.

Great review, Wheezy! Many thanks!

one of the best reviews of these headphones ive seen here and im on a rabbit hole of review videos of it.

Thank you for the exceptionally detailed review

Man, you´re going to become my reference reviewer!. I used to own the 4xxs and I fully agree with your description. Although I enjoyed them a lot with spacious, instrumental music the likes of Jean Michel Jarre or Mike Oldfield, the huge soundstage and separation and somehow recessed vocals transmitted overall coldness for other styles. I have not tried other planar so I do not whether it has to do with this model or with planar in general. The audezes are said to be warmer and a more forward midrange, but so far I had not have the opportunity to test them. It would be great if you could do it for us our followers :-). Kind regards!

You should check out the K7XX, although many people complain about the quality.

Thank you for your review. I only have two wired cans: DT 990 Pro and DT 990 Edition both 250 ohm both with Brainwavz XL pleather pads which increased the bass slightly. Now I'm considering these headphones as my first foray into the planar world....consideration over. I just ordered them for $159 right now with free shipping so they were $171 with tax. If I don't like them for music I'll definitely use them for gaming as I need a richer sound during battle. I had the monolith m1570 in my cart but just couldn't complete the purchase.

Great job on reviewing this one! What head amp do you use or recommend, and what low filter do you use? Thank you

My first pair of Planars. I have paid 145 euro with delivery. You can drive them with LG v30 :)

Great review. You deserve more subscribers. Cheers.

Just got these in for 130euro in Ireland, they came into Ireland from Germany(dhl centre) so I got to skip out on custom duty etc :) Have the Seinhiesser 58x's but wanted something a bit more spacious and with bass capabilities. Looking forward to trying them properly.

should i get the he-4xx or the dt 770? Will be using them for gaming and music but mostly just watching (youtube and other stuff) Also love the way you review them where you take some time for build quality and talking about the whole headphone instead of just the sound, and when you do get to the sound you try to explain it and then at the end show measurements, which is a plus for people like me who don't understand measurements

Intense great review. Thanks

Any luck hammering out that peaky treble with EQ Wheezy? Living in the Antipodes I would never buy Hifiman headphones, I just don’t trust their reliability, but these cheaper ones (through Massdrop) might be worth the risk.

Great review Wheezy! Do you mind sharing your EQ profile?

good review, subbed!

5:00 Seriously... 🤔 I was interested in these but they do seem to lack in build quality.

Hello Wheezely reviews, should I pick sennheiser hd 599 or this for 75% music and 25% open world gaming? I need a tight punchy bass that is enjoyable and the sound needs to be smooth, I will initially use them from my phone but I'll upgrade to a dac amp later. Which one should I pick?

man i freaking love them but for whatever reason it's bugging my left ear, i think they keep sliding or something i find myself that i'm constantly readjusting it , and i also hate the no padding on the top lol i don't know what to get at this point

Hi there! Did you get the Fidelio X2HR last week on amazon uk? Would like to see your review on those. Cheers!

what exactly is that sizzle in your audio? There's some kind of weird rattle going on, and it's definitely distracting.

can i use these with my electric bass amp with the 4.4mm adaptor?

Wheezy, so is there a massdrop headphone you do recommend for competitive gaming? Thanks!

mine are stupid stiff they must have changed it i cant almost not move them

Little disappointed for the competitive gaming part... Purchased these because I play a lot of Escape from Tarkov, where the sound positioning is crucial. Hope these will be good

What would you recommend for a good eq software on PC?

Know of any balanced aftermarket cables for this?

How is physical condition of headset now. I heard lot of quality issues after some time.

hard decision for me, im interesting in this and the hd6xx, for my first headphones =/

tbh on products like these, i would want youtubers to use the product for a month or 2 and then give their opinion on the product since i have heard their build quality sucks, and you can't actually talk about quality after using it for one day.

Just got them for 140$!

A synth will sound different on everything. What exactly does synth sound like? 20 different headphones, 20 different sounds. With acoustic instruments, you have real-world references.
