HE400se

Bought the HE400se for $60 and finds it sounds nothing like people described, and doesn't need an amp.

Modded their HE400se to reduce sound leakage and it still sounds fabulous.

Calls the HE400se a steal: harsh at first but much better with EQ.

Is seriously disappointed in the HE400se for gritty, bass-heavy music even with a Schiit Magni.

Finds the HE400se spacious enough to place sounds near and far in games.

Prefers their HE400se at home over the KPH40 and Modern Retro, with amazing bass at times.

Finds their HE400se perfect with a balanced cable, sheepskin pads and Oratory EQ, a little gem.

The HE400se blew their mind for its price, with bass that can rattle teeth on a Magni.

Paid under $70 for the HE400se V2 and finds it punches way above its price.

Impulse-bought the HE400se for 54 euros and was amazed by it.

The right ear of their HE400se bought in April 2025 suddenly stopped working.

Runs the HE400se balanced from a Douk U5 with Oratory EQ, a great inexpensive setup.

Nothing beats the value of their $50 HE400se; they'll keep it until it falls apart.

Loves the HE400se; with EQ it is almost perfect.

Would not buy the HE400se at any price: unbearably bright and needing mods or EQ.

Was very happy with the HE400se for the price before moving to the Edition XS, using a strap to improve comfort.

Thinks their entry-level HE400se sounds insane on a good chain.

Was blown away by a friend's HE400se: godly bass and great separation compared with their HD560S.

Their HE400se sounds thin in vocals and bass with lacking dynamics on a dongle DAC.

Used the HE400se the longest of their headphones and its hinge hasn't failed like the 4XX's.

Has the X2HR and HE400se and keeps coming back to the HE400se, though it needs EQ.

Modded their HE400se headband with leather because the original flaked and left residue.

Just received the HE400se and was struck by how open it sounds, like not wearing headphones.

Finds the HE400se a competent introductory planar, competitive under $100 at current prices.

Owns the HE400se and M20x and finds the HE400se a really fun listen while the M20x is mediocre.

Isn't a fan of the HE400se: very sibilant without a competent amp and still lacking with EQ.

Got the HE400se for about $60 and thinks their Moondrop Aria sounds better.

Had the HE400se and HD560S back to back and found the HE400se sounds broken by comparison.

Owns the DT880 and HE400se and finds both really good, especially for jazz.

Their HE400se sounded distorted in the low end at first, a rollercoaster first week.

Has the HE400se and HD600; the HD600 is better but far pricier in Asia.

Really loves their HE400se and would buy it again for $109 without hesitation.

Bought the HE400se on sale for 53 dollars; neutral-bright with great resolution and surprisingly punchy, precise bass.

The HE400se is very capable and sounds crazy close to their HE6seV2 on their chain.

Replaced the HE400se's loose, uncomfortable headband; doesn't love the midrange but the rest works for them.

Just got the HE400se as a first planar after a DT 990 PRO: neutral impressions so far, a bit heavy, and the cable feels mid.

Fine with the HE400se's build and comfort for the price, but upper-mid and lower-treble peaks make it hard to listen to after about 10 minutes.

Sold their HE400se because the headband hurt.

Resold their HE400se: okay for the price, but the HD 560S or ATH-R50x are more agile and dynamic for them.

Liked their HE400se for open-world games and music, but after a year the headband yokes broke on both sides after a drop, and the cable kinks easily.

Their HE400se has been going strong for about three years.

Their HE400se v2 has much deeper bass than their MB Quart K800, but you hear it rather than feel it, with no punch.

Two HE400se pairs developed driver rattling, as did the replacements, which they fixed only by disassembling and re-tensioning the drivers.

“2x HE400SE, 2x Ananda Nano, both developed driver rattling, and one of the Anandas sounded wrong without a clear cause I think they were out of phase.”
