A few weeks ago, I got my ears around the Massdrop HD58x Jubilee and have been in a conundrum of my own ever since. I have owned every Sennheiser model in the HD over ears series and enjoyed pretty much all of them, save for a few. Unlike the HD6XX, the Sennheiser HD650 is not much recent and has been around for a while. And it has achieved a certain amount of popularity among both professional and domestic users. It has very easily fitting oval earpieces and the whole model is really smart and completely no-nonsense. All the parts are of good quality, but if you use the headphone for a long time, you might need to change or replace many parts. As the drivers might start creating distortion and rumbling sound, or the headset might become loose. But the good thing is you can replace those parts without any hassle. Sound Quality With a very decent depth, the stereo imaging is very amazing too. So, in conclusion, audio-wise, the HD650 is a particularly attractive headphone that can provide any audiophile with a great audio experience.

In these formative days of headphone audiophilea I recall being at a meet in College Park, MD where there were a number of HD600s and HD650s. We were auditioning cables by Cardas, Stefan AudioArt and other DIY concoctions including pure silver cables. It was amazing what a difference the cable could make to the signature. Imaging: a little weird. Vocals are up front and centre all the time and instruments tend to blend together despite the wide stage they are placed in. In the way of raw fidelity, the HD6xx scales so much with superior gear that it makes it the better overall value for audiophiles. The HD58x is the better value for casual listeners who don’t have an expensive rig. Now, it does have surprisingly good imaging chops and presents music in a fairly wide stage with good (but not amazing) instrumental positioning, but that’s almost expected given its earspeaker-like configuration. The separation on mids and bass is average. I found it not enough, and it contributes to a poor sense of detail. I could hear all parts of my music though; think of it like a fuzzy picture. Sound bleeds together even though its all there. The treble escapes this poor separation however.Also by its appealing detail rendition, the wearing comfort and the authentic sound, especially in the voice reproduction, it is indeed a value that is hard to top, since the HD6XX is above all a weapon in tonal terms. What I’ve said in my initial impressions still hold true now; yes, the changes made to the HD8XX does cut the treble peakiness of the HD800/S significantly, but introduces a slew of other even more troubling issues that completely overshadow that fix. Again, seems analogous to cutting off an entire limb in response to being asked to lose weight.

And there are so many great headphones from different brands currently available in the market, from which you can choose the one perfect for you. And you should be careful about choosing the headphone as different kinds and models of headphones offer different things, and you should choose the one according to your need and spend your money on that. A bit rolled off, not really sure what else I have to say. It's just smooth, non-piercing, etc. I think I can hear part of the famous "Senhessier veil". Try songs like Hannah Diamond – Fade Away. That song has a quite bright female vocal and while it won’t take it away, it’s a bit less airy. Crinacle also likes the Dusk which is one of the worst IEM that was ever made. I have not met a single person that likes the Dusk in real life. Everyone just says the treble is so painful, they rather not listen to music. Disclaimer: The Massdrop x Sennheiser HD 58X Jubilee was sent to us a sample in exchange for our honest opinion and does not have to be returned. We thank Massdrop for this opportunity.

Given the KSC75’s mid-bass emphasis and forward upper-midrange response, I would classify it as a “bass rolled V-shape”. The measurements I’ve done correspond with my subjective impression on its tonal profile. Sennheiser doesn’t quite claim that, but hype has been slowly building where the HD560S may be a viable replacement for the legendary HD6X0 headphones. My interest was piqued but now they have my attention. Is the HD560S all that’s cropped up to be?

Choosing the right DAC/amp is important here, as it could mean the difference between well-balanced audio and sibilant treble and upper-mids. Either way you won’t get an overbearing amount of bass response (that’s a good thing in our opinion) and should expect a decently wide soundstage and imaging. I originally didn't notice because in music I couldn't tell the difference. I still can't. I don't think I listen for that kind of stuff, and my music probably doesn't take advantage of positional audio enough anyway. The difference was only noticeable in competitive shooters, specifically Apex Legends. I got these because I had the DT 880 and wanted soemthing that was darker while still being neutral and not too expensive. These were recommended to me as fitting that bill and also being similar to the HD650, so it would also give me a chance to hear what others people frequently reference. That is one of the main reason I bought them as well, they were something tons of others have tried and I could compare my opinion to theirs to get a good internal reference. I used them with the CEntrance DACport HD. DROP (formerly Massdrop) is in the end nothing more than an online shop. But with the subtle difference that they also put their resources into product development with well-known big players. In most cases, the aim is to revise or reissue an existing product, make it more cost efficient and thus make it accessible to a wider audience. Examples are the AKG 7XX, HIFIMAN HE4XX, or the SENNHEISER HD6XX, which is based on the HD650 in terms of sound and appearance. This is still listed at SENNHEISER for 459 €, but is available at Thomann for just under 340 €. Well, the HD6XX is available via DROP for about 185 € and that without big differences in processing and sound (if you can believe the manufacturer, since I can't make a direct comparison at the moment). DROP also produces on demand and therefore in different batches, hopefully with the same quality control. So the product is not available on the shelf, but only exclusively through DROP and therefore not permanently. The entire construction is made of plastic and along with stiff cushion pads, the old HD series discomfort issues play a role in my life yet again. These are not comfortable when you first buy them or use them new. It takes some time for the pads to soften up and the headband to stop clamping. It needs usage.

So apart from being perfect in sound, it also offers an open stage sound range. You can find amazing details in different music that you weren’t able to find before. So, as a whole, the HD6XX is top-notch regarding the audio system. Things You Need to Know You’re not expecting much, I’m not expecting much, so let’s just rip the band-aid off. Obviously, the sub-bass response of the KSC75 is its biggest weakness that cannot be fixed with mere EQ, so don’t get one if you value dat rumble in your music.
