1MORE H1707 Triple-Driver Over Ear

May 12, 2020 at 11:30 PM Post #1,171 of 1,601
Now, if your phone is a clunker that is known to have poor audio (like some older Samsung Galaxies for example), then I would at least consider something like an EarStudio ES100 (wireless), or a wired DAC dongle (Meizu DAC Pro, xduoo Link, ibasso DC02, etc) if you don’t want to lug around a stackable amp.

They sound darned fine off of the Fiio BTR3K fwiw!

Make sure you remove the layer of thick foam on the back of the replacement Beats pad. Some of them peel off cleanly in a full sheet. Others have have to be gently ripped off. It depends on the actual 3rd party construction of the Beats pad. There will still be a fabric layer remaining, which should be left on. Only the foam layer should be removed.

I followed all of your excellent directions and managed to get it done. Comfort! Awesome!!!

I knew I'd say this... Why didn't I do this sooner???

Does anyone find the bass on these kinda "blobby"?

Love me some blobby bass lol! Seriously, the bass is kind of unique, but I love it.

Btw, which pads are you sporting?

My latest H1707 mod:

- Passive radiator delete
- Internal cup rework
- Stock dynamic driver retune
- Fully open-backed conversion
- Brainwavz HM5 hybrid velour/pleather pad
- Custom balanced SPC upgrade cable

HUGE soundstage compared to stock, and I tuned it to have a more balanced/neutral sound tuning. The HM5 pads are oh so comfy; much more so compared to the Beats pads or stock pads.

To anyone that wants to fit larger pads on the H1707 (such as HM5 or Shure 940 pads), the inside molding of the stock 1More case can be easily trimmed away with an Xacto knife. This allows the headphone to easily fit in the stock case:

If you are careful when you trim the inside molding out, you can even preserve it so that it can be laid back (or glued back) into the stock case (in case you ever sell the headphone, for example):

Of course no case mods are required for the Beats pads mod. The stock case is (barely) compatible as-is with the Beats pads.

I have several pair of H1707. 3 western silver (graphene) and 1 asian gold (titanium). I like the looks and quality build, and I'm OK with the quasi-on ear pad size and depth. I prefer the frequency response of the western silver to the asian gold.

Tonight I was curious about about the physical aspects of the tuning and specifically how the passive radiator works. I'm quite familiar with passive radiator designs in loudspeakers and have build subs using them. Perhaps they exist, but I've not seen or heard other headphones that utilize a passive radiator in their design so I was curious to understand how the 1More designers went about integrating a passive radiator into this headphone..

I removed the 3 screws around the Lamborghini wheel on the back of the cup. I found the small hole in the glass underneath that I expected to find after reading posts here. The glass is glued in and effectively seals the back of the headphone (except for that pin hole). I slipped the pointed end of a pin through the hole and confirmed that the passive radiator does indeed move and behaves when pressed just like a passive radiator should. The center piece is solid and appears to be machined aluminum. The surround is compliant rubber. There are vents around the passive radiator that connect the airspace in front of the radiator to the airspace behind it. This puzzled me since almost every sub alignment I've seen with a passive radiator was otherwise sealed. Tapping on the cups with my finger produces a low frequency resonant ring which I expect is the passive radiator at its resonant frequency.

That got me curious to see the passive radiator in action. And here's the part I'm puzzled by. I tried a low frequency manual sweep from 120hz down to 10hzwith a signal generator with enough amplitude to move the active driver to its considerable x-max. But at no frequency was I able to see the passive radiator move at all. Sealing the pad (like when the headphone is worn) seals the volume in front of the driver so the x-max of the active driver becomes limited (exptected). But pad sealed or not, the radiator doesn't move. I even rested the pin through the hole on it and cranked it up for a final sweep hoping that i'd see some sign of life from the passive radiator moving the pin. Nope. Completely still at any volume and any frequency.

I suspect that the vents I see around the radiator are effectively coupling the airspace in front of and behind the radiator so that there is never a time when the pressure is different on either side. Thus, no movement.

So, I wonder if I'm missing something or if the passive radiator is really just for show and "triple driver" marketing.

Have any of you H1707 owners observed the passive radiator on your H1707 actually radiating?

As you mentioned, there are air channels around the sides of the cup, creating dual chambers that are coupled together.

Whether there is a true helmholtz resonator effect, and at what frequency/frequencies it would occur at, are unknown (only 1More would know).

So yes, IMO the radiator is just for show. I do, however, know that the bass sounds odd when the radiator is not glued all the way around. On my gold pair, I had discovered a while ago that the radiator glue had loosened and portions of it were ‘flapping’. Instead of re-glueing it, I just removed the radiator altogether (on the gold pair). I have since heavily modded the headphone, converting it to an open design.

I have never considered the H1707 a true triple driver. I have always seen it as a dual driver headphone. The passive radiator has always just been marketing.

Quartered Walnut (would probably look best on the gold H1707):

Edit: Yup, as I suspected, the walnut looks much better in combination with the gold IMO. I’m going to find a darker wood for the grey pair, like black ebony or purpleheart etc.

Slater those look incredible. I’ve got a gold and a silver set. Was thinking about putting on the beats pads. Am I better off going for hm5 pads?

It depends on how compact you want them. The Beats pads are still compact enough to wear around the city without looking like a fool. They are also still compatible with the stock carry case.

The HM5 pads are full size pads, so you will get ‘huge headphone eye rolls‘ in public due to them not being the most practical. HM5 pads also fit very loosely on the cups. They do seal properly once you actually put the headphone on, however. But because of the loose and floppy fit, you occasionally have to line the pads up straight before you wear them. It only takes a second though.

An advantage of the Beats pads is that it preserves the stock sound tuning, while increasing comfort over the stock pads.

An advantage of the HM5 pads is a huge increase in comfort, PLUS the ability to tweak the sound by pad rolling. There are numerous designs of HM5 pads available, all of which will change the sound tuning - velour, hybrid, pleather, sheepskin, fabric, angled pads, etc.

My silver pair have Beats pads, and my gold pair have HM5 pads. I like both of them.

I have a pair of HM5 pads, but my Nighthawks don't want to let them go lol. Actually, I would try it, but having just stuck the beats pads on, I am reluctant to peel them off in case they won't stick again.

Will they stick again Slater? Will they? Huh? Huh?? ;-)

I am not sure about that. I have never removed and restuck the Beats pads. I would say no, since they use double sided tape that is designed for 1 time use.

I have seen the adhesive pieces available separately though. So if you remove them and the tape does not restick, you could just put new adhesive onto the Beats pads.

Have you ever NOT had a solution? :beerchug:

I found them on ebay.ca, and the price (with shipping) for 2 of them was the same as what I paid for the pads. So instead, I bought some Scotch Double Sided Tape for the same price (approx $13CAD on sale). I figure I can get the pads back on using that stuff. And since I will have 3000 inches of it, I figure I'll be able to unmount and remount the beats pads approximately 600 times (assuming it takes 5 inches of tape per pad). Pad swapping here I come!
