I'm an owner of the Yamaha Pro 500's, and I've had mine for almost 3yrs now. What others have said is true, they sound amazing overall and they absolutely SLAM. The only set I have heard that hits harder are my SZ2K's. But the 500's do it with ease. They don't need tons of power, and they don't...

So I got my hands on a pair of M50x pads to try on my ATH Pro700mk2's. When I was researching those headphones, it seemed the M50x pads were by far the most common replacement/upgrade. Well the M50x pads do offer more comfort over the stock pads, but are no where near as comfortable as the...

Awesome, glad you tried them out. That equalizer looks very nice!   I have multiple EQ presets for my SZ2K's, that just happens to be my most used. But even with those settings I can get the SZ's to maximum impact level while listening, but I do like to listen very loud at times which was why...

I used it exclusively in the past, and found it worked great. But once I discovered Equalify Pro for equalizing Spotify, I stopped using it. I still have it installed on my PC, I just currently have it disabled as it is a system wide EQ, which was why I chose it in the first place. Anything...

I'd also go with the TH-X00's because they will compliment your 400i's better than the X2. You already have a very detailed open back headphone with solid sound stage. The X00's will give you a fantastic closed back option that still have respectable highs along with top tier bass. And honestly...

I do not own the X2's currently, but I may pick them up in the future. But what I can tell you is yes, the bass will give you a physical rumbling effect when amped and EQ'd properly. I did own a pair of X1's in the past, which supposedly have more bass bloat than the X2's, and can tell you the...

Yes they do, but I don't use them and have never had a problem with them coming out of my ears. 

  I own the GR07BE and can tell you they are a fantastic fit, and with the cord looped around the ear you will never have to worry about them falling out. If their sound signature interests you, I'm here to tell you they would work great in the gym. Out of the many IEM's I own, they "lock in"...

I do not own the X2's, but I did own the X1's for awhile. I absolutely love my bass, but like you appreciate the rest of the sound spectrum as well. Like Music Alchemist I also own the SZ2000's and find them very respectable sounding overall with my EQ settings. They did require lots of time to...

Alright, here we go. I'll list them out for you starting with HZ, gain, then bandwidth.   15hz, +2.0db, Q0.9 30hz, +5.1db, Q1.0 58hz, +5.0db, Q1.5 85hz, +2.0db, Q1.5 160hz, -3.8db, Q0.8 300hz, -5.3db, Q0.9 500hz, -4.4db, Q1.0 1khz, -1.4db, Q0.9 2khz, -0.8db, Q0.9 3khz, -0.6db, Q0.9...

A quick paper test vid I just did with my Mahogany TH-X00's. As you can see in the video, they are absolutely murdering the paper! I'm heavily boosting the sub bass via EQ, and driving them from my iFi iDSD on Turbo. I really think a lot of the bass is lost in transfer to the head from their...

Here is a picture of my main EQ preset I use with my SZ2000's. I have many different presets, but I use this the most as it sounds best with my favorite genres of music (hip-hop/EDM). This preset also generates maximum impact, and pairs nicely with my iFi iDSD. What you don't see is that I have...

As long as you have plenty of power and are willing to EQ in a big boost in sub bass, they are a fantastic portable basshead can. Seriously, these things with HM5 pads are legit. Heck, if I didn't already own my SZ2000's these would be my main desktop basshead can as well.    If anyone is...

I agree 100%, comfort with close to maximum bass is ideal. Which was why I bought the HM5 pads for the 700's in the first place over the M50x pads.   For me, I don't see myself pad rolling my 700's very often. That's the main reason I have the 55x pads on my SZ2K's instead of the HM5's. I use...

I'm tempted to try the HM5 sheepskins I just bought and installed on my 700mk2's, on my SZ2K's. If it wasn't such a major pain in the a** to install them on the 700's, I already would have tried them on the SZ's. I picked up a used set of 55x's off amazon at the same time I ordered my SZ's to...
