Review: Great audio quality for a good price. - Purchased on June 10th, 2023, for about $55. I have a very difficult time with headphones, since the current market seems to only value a 'sleek' look and wireless functionality, hence the advent of the dual "innovations" of wireless headphones and earbuds, which have culminated in the supremely awful experience of the wireless earbud -- tinny, awful-sounding, uncomfortable, and extremely easy to lose -- all for the "low-low" price of a pair of good open-ear headphones. Blech. The alternative to this high-tech e-waste is usually the classic older 'portable headphone' design -- but this market space, from what I have seen, is largely dominated by cheap products with no staying power. At one point, I used a pair of very cheap foldable headphones (about ten dollars,) and while I was very pleasantly surprised with the fidelity of their sound (especially when compared to the awful sound of hundred-fifty dollar earbuds,) their durability and comfort left quite a bit to be desired. These HD400S headphones are a very refreshing alternative -- comfortable to wear, durable, and shockingly high-fidelity. I wouldn't want to use these as my primary headphones (that honor is reserved for other non-portable Sennheiser models!) but they work fantastically with my phone or MP3 player, especially given their essentially negligible power draw. My only issue, which is a fairly small one, is that the headphones sit sort of strangely on the ears -- not quite like a closed ear headphone? I think this is responsible for how comfortable they feel, even with the fairly cheap earcuffs, but it does lead to them falling off fairly easily in heavy wind or similar conditions. I've only ran into it a few times, and they do seem durable enough to handle a few of these sorts of falls, but it's something to keep note of.
Review: Amazing Value, Excellent Audio Quality - Possibly the best price-to-performance headphones on the market. I use these every day for hours and I get zero fatigue in my hearing or on my head and ears from wearing them. I use these with my PC for gaming and my phone for music and podcasts as well as calls. Sound quality is excellent, at least as good as headphones I've heard in 200-250$ range from other major brands. Call quality is a significant step up from my Galaxy S24 Ultra's mic and speaker. My father was in radio for many years and I was lucky enough to be able to try a variety of higher-end sets of his and of his coworkers. These are on par with the best of what I've heard in that professional setting. One of my favorite features is the replaceable cable with mic. Since I'm moving these around between sources frequently the 3.5mm jack tends to wear out after about a year. Much of this wear was likely from my old phone which I used for about 5 years allowing it to collect a lot of debris in the ports. This has been the primary cause of failure for several pairs of cheap headphones I had tried before getting the Sennheiser HD400S's. I'm so happy I was able to replace the cable for around 10$ and avoid replacing the entire set. I am not a wealthy person and these headphones have been an incredible investment in the quality of sound I get from my entertainment and calls. 9/10. The only thing imo that could be improved would be the mic sound quality, however it is tiny and almost invisible on the cable. Mic audio is totally serviceable, no one should expect studio quality from a 1/4 inch wide microhone.microphone. The headset itself has taken many falls from chest height when it's slipped off my PC's makeshift headset hanger onto the floor. Seems to be none the worse for wear. I highly recommend the HD400S.

## Questions & Answers

**Q: what's a compatible replacement cable for this headset that does not have the inline mic?**
A: The HD 400S uses the same "bayonet" type click and lock system as the HD 5XX Series products. Replacement cables, with and without an in line mic are available.  There are many aftermarket options available on Amazon.com.

**Q: How big are the ear cups (inside diameter please ...if you can)?**
A: At its' widest point, it is as long as my index finger across.

This is -not- your typical "over-ear" headphones and is more of an in-between. It's not fully ON EAR and it's not fully OVER EAR.

At first I was disappointed, but it's actually really comfortable. I forget I'm wearing it, sometimes.

**Q: Do these have a lot of bass? I don’t want a lot of bass. I want a nice clean smooth sound.**
A: No, it doesn't have a lot of bass.  It focuses on strong mids and clear highs. Acoustic and/or synthesized (electronic, atmospheric music, etc.) sounds come through really well.

**Q: The one button remote controls volume too?**
A: It technically does, but it requires you to double/triple tap and then hold on the last tap. I have a lot of trouble double/triple tapping fast enough for it to register as something other than pause/play.

### ⭐⭐⭐⭐ Low-end, but still better than most.
*by S***Y on September 8, 2020*

I've had these for a few months. We've always been a Sennheiser family. When I saw these, I got them for an extra set for travel. Here are the pros and cons I've noticed; Pros: The ear coverings are very comfortable and very noise-canceling. I cant even hear my cat meowing on my own lap with these on. They fold up nicely and dont take up much room. They work. Sound comes out, which makes them successful headphones. Cons: The wire is quite short. Thankfully it can be easily replaced, but as far as the one that comes with these I feel tethered. The part that swivels for extra comfort and makes it fold also makes it easy for my hair to get caught. Once it's in there, it's hard to get it out. Sound quality is average. In comparison to every other Sennheiser we have, these sound a bit tinny. It's still miles above Beats or some lower end Bose. But that rich bass sound I depend on lacks a bit. Overall, I still give these a 4 because they're not hiding anything. These are the low-end Sennheisers and some things wont be as good as the $200-300 ones. If this is all you can afford, it's a good purchase. If you're looking to cheat the system and think you're getting ultra high-end..... nnnnnnope.
