Mids are sharp, very nice to listen to, the lows go really low and the highs are crisp but the overall sound is still non-fatiguing, I can use these headphones for hours without any problem. Finally I replaced my G6 due to problems with the drivers and because I wanted a better-looking DAC with multiple inputs (the G6 has both USB and mini-Toslink inputs but only one works at a time and you can't switch manually between them). So I bought a Topping E30 to test. And, oh boy was it good.

the sound signature may be more appealing and accessible to the average person who knows absolutely nothing about the audiophile hobby and prefers more bass out of their experience. Bass Quantity: HD650 = HD58X > DT990 >> HD598 (some people, after seeing HD 58X’s graph were thinking that these were going to be darker sounding than the HD650, but that's not the case. They have similar bass with the HD 58X having a bit more sub bass rumble in it)

Whoops!

If I could use an analogy, the sound of the 58X is like a photograph that has just a hair too much contrast. It seems babies are all the rage these days and everyone’s having ’em, but they don’t mix well with audio. xD One difference you’ll notice here vs. others in the line is the bass; there’s more of it for sure, but it’s still not over the top.

It may not tonally superior to an original HD600, and it’s certainly not tuned as well as a 560S, but none of that really matters much as it could be more enticing to a newbie audiophile (plus, it sounds great and that’s really all that matters at the end of the day). In other words, The problem for some is that the direction of said sounds can be a bit hard to pinpoint, but I personally don’t have much of an issue with it. FilmTwo real reasons, if you have a high performing amp, outputting more power reaches higher SINADs (not an actual reason in practice, but is when technically speaking). The 58X is definitely the most “fun” or “colored” sounding out of the 3, while the 650 is assuredly the warmest and most “syrupy”.

I can recommend the MASSDROP Sennheiser HD58X JUBILEE without EQ. With EQ, it is a hair from getting top honors from me! Then I upgraded my setup with a Brado Audio Ocean, connected to the Line Out of the G6, and the sound improved as the warm sound of tubes goes really well with dark-sounding headphones like the 58X. Remember when I told you in the HD 598SE’s review that those had one of the most boring and flat sounding bass? Well, these headphones are just the reverse…. They have bass that can bring a smile to anyone’s face from a hardcore bass head to a proper audiophile.

BAM!

Then after a few years he launched the HD 580 Jubilee which was basically a HD 600 and then later on released the HD 650, which even to this date, is used as a benchmarking tool for all other headphones. The 58X may actually be better because it has that spicy flavor that makes the film more lively and engaging. With the 58X, you’ll notice everything just seems a bit louder, with a little more oomph and sparkle. If you plan on purchasing these headphones or any other high-end headphones for that matter, I suggest you get a good DAC/AMP to go with it. It will go a long way to make your listening experience much more enjoyable. It’s definitely not wide like a K702, but it can be out of your head; more so than an HD600 or even a 650.
