I purchased these headphones at the beginning of this year to use for full-time tertiary study with a significant online component.On the positive side - the sound is great, and my fellow students appear to be able to hear me fine when we're in Zoom tutorials so the mic is good too.On the downside - these are advertised as over-ear headphones, which I wanted for comforts sake as they were going to be used for extended periods, but they aren't. The cavity in the ear-cups on these headphones is only 3.5cm wide so the pads unavoidably sit ON-ear - and I have small ears. The pads themselves are nice and thick and squishy, but still cause significant discomfort after extended wear.

For the size of my head and ears, this headphone is slightly on the small end but with it set to the max position, it fits on nicely, the earcup is a bit narrow but I adjusted to it after a few days of use. The head band of this headphone is quite think and not as comfy compared to some other ones, however the great sound clarity and bass really makes up for a pair of good headphone. The bass of this headset is good and clear, at the same time it feels completely different to bass that are exaggerated and noisy, the driver and tuning of this headset is definitely professional and good for the price, however this will fall short when comparing to other professional studio headsets, but for the price, this is a big win.

I have these now for about 2 weeks and I am very happy. This was a replacement for another pair of Sennheisers, some HD300 where the headband snapped - so much about Sennheiser being robust.These are straightforward wired headphones, no Bluetooth or noise canceling. You pay for sound, no features or gimmicks.I use the HD400s mainly for music, some movies, and a little gaming and they are suitable for all of this.Sound is very nice on the Focusrite 2i2 Gen 3 audio interface that I generally use them with. The 2i2 has a very nice DAC but the amp is not very powerful. The HD400s also performs very well on my phone or a FiiO M6 DAP.The HD400s feel more robust compared to the HD300 and the sound is better over the entire spectrum. Punchy bass, beautiful mids, and ... MoreI have these now for about 2 weeks and I am very happy.

Punchy bass, beautiful mids, and crisp treble. Compared to the HD300 I can hear more details in music, the bass is deeper and there is more soundstage. The HD400s sound on par with a set of Sony headphones that cost me 5 times more.Comfort I would say is similar to the HD300, these are light and can be worn for hours.Happy to give them 5 stars in their price bracket.

Earphone sound. Good noise. Fold it to make small! Very convenient for to work out at the gym. Also very convenient for to work not out at office. Only dropping one star off because the plastic casing seems brittle after repeated folding and unfolding, so maybe be a little gentle for longevity. Otherwise excellent product with excellent sound!

Angela's review of Sennheiser HD 400S Headphones - Black

Pros: I've been using sennheiser for years, the quality has gone downhill last few years and the quality of the sound on these are very poor, I use a cheap pair of cx300 II with my Sony music pod, and the sound quality is absolutely amazing the clarity and base is unreal so got this model to use at home for this, and very disappointed, the sound is very poor, little base and no clarity at all, I've had cheap pair of headphones for less then £5 with better sound. Only good point is comfort, and only any good really for listening to the TV, I don't recommend these if your into good quality hifi or studio sound quality as you won't get that from these. Such a disappointment for such a cost, I will stick to my CX300 II's in future best £10 ever spent on earphones. Don't ... MorePros: I've been using sennheiser for years, the quality has gone downhill last few years and the quality of the sound on these are very poor, I use a cheap pair of cx300 II with my Sony music pod, and the sound quality is absolutely amazing the clarity and base is unreal so got this model to use at home for this, and very disappointed, the sound is very poor, little base and no clarity at all, I've had cheap pair of headphones for less then £5 with better sound.

Don't waste your money on these other then for basic sound or not too bothered about quality. Cons: Sound quality is terrible for the price, considering the HD 280 pro are good and not much more in price, need to focus on less folding up design and more on base and clarity.

Good sound, slightly uncomfy

The HD 400S are the first pair of Sennheiser headphones I've ever owned. Having heard a lot about the brand for several years, I had high expectations for both the sound quality and comfort. Everybody knows the audio quality you're getting when you purchase a pair of Sennheiser headphones -- that wasn't really in question. However, I wear glasses, so I was really looking for a set of headphones that I could wear for long sessions without pain from contact between my ears, glasses, and ear pieces. For me, the HD 400S pass the test. Unfortunately, where I've been slightly let down is in the contact between the top of my head and the headband. It varies, but on average after about 1 hour of wear, the top of my head starts to hurt quite a bit. It's not unbearable, but ... MoreThe HD 400S are the first pair of Sennheiser headphones I've ever owned.

All things considered, this is a good set of headphones that I could happily recommend to a friend on a budget, but might encourage them to spring for a pair with a bit more padding in the headband.

Mick's review of Sennheiser HD 400S Headphones - Black

Pros: They're light and comfortable, fold away neatly. Storage bag is a nice touch. They do a reasonable job of attenuating external sounds. The sound quality of the output is certainly serviceable at this price point but I wouldn't say they could be used as monitors in a studio. That said, studio users wouldn't be buying them for that. They are eminently suitable for gaming if you don't mind the lack of a microphone but just want to protect others from your racket.Cons: The lead is, perhaps, slightly too short. Another 0.5m would have been welcomed but that's perhaps down to personal set-up.

Sennheiser HD400s Headset

I am an audiophile who has owned separate systems for decades and I like fairly good quality and nice sounding music. When my wife's Sony headset stopped working I searched the internet for a better quality headset with sound quality and budget in mind. I have used Sennheiser products in the past and have been always impressed by the well balanced sound and clarity and when I saw the set of Sennheiser HD 400s discounted to < £50 I bought it. Below is a summary of my findings; Good 1) Nice balanced sound quality especially in the high and mid range. Bass is tight if a little light for some tastes but suits my wife and my musical taste. For the price the quality is very good and very suitable for use as a headset for conferencing and for listening to music. It won't ... MoreI am an audiophile who has owned separate systems for decades and I like fairly good quality and nice sounding music.

For the price the quality is very good and very suitable for use as a headset for conferencing and for listening to music. It won't replace a £200 set of audiophile headphones but what can one expect at this price! 2) Good quality materials and very comfortable 3) Detachable cable can be replaced and reduces the risk of damage whilst in storage/transit 4) Foldable but sturdy construction makes it easy to store away and carry for the commute Bad 1) Microphone has no volume control but requiring volume controls at source. Not a problem for us. 2) Not bad but for those who like an emphasis on heavy bass then this may not be the pair for you. Overall I am very impressed and my wife is absolutely chuffed.

Superb sound and quality for the price

I had been using a "cool brand" set (popular with the kids) when they literally fell apart as I took them off. Headband snapped in exactly the same place as my son's had done six months earlier. A quick look at bodge repair vids on YouTube soon showed this was not a rare occurrence.I needed a wired pair as I have a home studio, and Bluetooth phones are unsuitable for sound and music production because of inherent latency issues.I already had the BT version of these (HD 350BT) which I love, and when I saw their wired brothers for under £40 I thought I'd give them a go.I'm amazed at just how good these are. Compared to the cool brand at four times the price, these dance all over them with hobnailed boots.For the money you simply just can't go wrong. Highly ... MoreI had been using a "cool brand" set (popular with the kids) when they literally fell apart as I took them off.

Working as I would expect.

I got these primarily to help me hear better in Zoom meetings as I'd often have trouble understanding voice (I'm not young and don't hear as well as I did). I find they solve that issue very well.I've also been using them for streaming services and the sound again is better than listening on speakers.As for the issue in a prior review of no bass... I don't see this at all. I've played around with my sound driver's equalizer and can get very nice sound and the music reproduction is every bit as good as what I'd expect from a lower end headset.These headphones are comfortable enough although after an hour or so I definitely want to remove them for a few minutes.All in all, worth the price. I've had Sennheiser before (decades ago) so I was not disappointed.
