I highly recommend the focuspad + grill mod
5 Stars
I highly recommend the focuspad + grill mod
I do find this HP having a balance sound, no dominating frequency, smooth and refine. However, what I immediately noticed after spending quite some time with the stock HE-400S is the evident bass and treble roll off at extreme frequencies. Comparing the stock HE-400S to my Philips X2, it didn't take long for me to realized these shortcomings. I find it disappointing especially after reading what people talked about the bass planar sound. I'm no basshead, but the lack of sub-bass leaves a lot to be desired. However, what makes me keep this HP in my collection and the five star is the ability to re-tune the sound by changing the pads. I also found a thread in headfi wherein people are getting positive results with the grill mod, majority of headfiers said it opened up the sound and added top sparkle. So I bought the focuspad and DIYd my grill. I found an aluminum mesh in amazon, and cut it using a Tin Snip (which can be bought at home depot for 10-12 bucks). Here's some of my impression with focuspad+grillmod as compared to my Philips X2, as always YMMV:- The stock HE-400S sound is a little bit on the warm side. With focuspad+grill mod, the sound signature remains the same, and it certainly improved the bass and treble response. The difference is so noticeable on low frequencies.- with focuspad, the bass sounds deeper, the attack is fast as you can expect from planar, tight and more impactful but most importantly the sub-bass is more prominent now, I feel that it really closes the gap with Philips X2.- with grill mod, there's noticeably more sparkle to the treble, there's more air and it opened up the soundstage a bit. I'm no longer getting the impression of the sound coming from a small confinement of a recording studio. There's definitely more depth, but not necessarily wider.- the stock he-400S has a slightly prominent mids. With the mod, it sounded more linear. You can hear what you need to hear across the frequency spectrum, I do find that everything is presented with the right amount of detail.- Whatever music I throw at it, it is very enjoyable and musical to my ears, and that's what really matters to me. I feel that it doesn't excel in any genre, neither nor it performs poorly. It doesn't have that huge bass of the HE400, or the analytical treble of the HE560 that people talked about. To my ear, it sounded more balance and rounded that will suite any music genre. The Philips X2 on the other hand is definitely on the fun and energetic side. It sounded best with EDM, live concert or any music that requires a lot of energy. One area where the X2 wins is it has more textured and articulated bass, on the other hand, the HE-400S has lush and detailed mid range. It excels in male/female vocal-centric songs.- Compared to X2, the HE400S with the focuspad+grill mod has decent soundstage but it has an excellent imaging. Think of the X2's ability to project a concert stage, while the HE-400S soundstage resembles a medium size auditorium hall. Most of my music files are acoustic recordings. To my ear they sounded a bit distant with HPs with big soundstage so I favor the HE-400S over the X2 here. Another experience on HPs with wide soundstage is the center image sounds hollow most of the time. With the HE-400S excellent imaging and musical coherence, the HE-400S wins over the X2 in this area.If anyone is interested on how the measurement would look like between stock, focus-a, focuspad, here's an interesting thread. Credits goes to the owner and posters of thread.http://superbestaudiofriends.org/index.php?threads/hifiman-he400s-with-focus-pad-measurements.189/page-2I believe these guys measured it with the stock grill. With focuspad, the improvement in the frequency response is accentuated from subbass to bass up to the lower mid-range (20Hz to 500Hz) as shown in the graph, and this confirmed what I'm hearing about the huge improvement in low frequencies. However, it muddied the mids as shown in the 1k-2kHz, definitely not my preferred setting but some people may like that slight v curve. To my ear, the grill mod uplifted the mids plus it added enough top sparkle. So for best result, I highly recommend the focuspad + grill mod.
