I purchased this set expecting I wouldn’t enjoy it as much as the Mangird Tea, but I heard they were very similar in tonality so I said what could it hurt? I love the Mangird so why not check out the H40?

I personally don’t feel the Mangird and H40 are that similar. The tonality is quite different. The biggest difference is in the low end. The Mangird is lacking low end energy where the H40 is not. The Mangird is not lacking in sub bass. So in comparison… The Mangird’s low end is clean and has a sub bass punch when the bass in a song hits low. It also allows the FR some space to allow the treble to sparkle which gives the Mangird a more detailed presentation than the H40. The H40 at times has a lot of bass. While listening to the H40, I’ve said to myself many times… “I might need to EQ some of that bass out”. But I don’t. I love it. It’s too much but it’s awesome.

The H40 is a very fun set. It’s not as detailed as the Mangird. The FH7 is more detailed than both of them. The H40 does a fantastic job at balancing the things that are important for a very enjoyable listen. Nothing is harsh yet it hits hard. It’s not super detailed but things are not too soft either. The H40 sound is full, thick, warm, spacious and ultimately FUN!

The H40 cable is fine. It looks really nice, but it feels a little sticky to the touch. It doesn’t have the formed plastic around the ears which I prefer. Some might see this as a plus. In comparison, the Mangird cable is awesome.

The H40 is also efficient. I’m usually surprised at where my volume is set at compared to other sets. Anything should be able to drive this set.

I don’t have driver flex issues with the H40. Because of the deep insertion, finding the right tips to fit and seal properly might be challenging but the H40 comes with a great assortment to get you started. I do get some inner ear suction I have to tweak the tip position to resolve from time to time, but that’s normal with a deeper IEM.

The H40 is also considerably larger than the Mangird. I love the fit of the H40. It fits my ear really well.

I’ll be keeping both the Mangird and the H40. The H40 is going to be getting a lot of play in my ears. I’m impressed with it and didn’t expect to be.

With this post, I hoping to be taking a break from this forum. It’s been awesome chatting about IEMs with all of you. :love_you_gesture:

H40 vs OH-10 for those who have heard both?

Very different. OH10 is V shaped, small soundstage in your face sound. H40 is more balanced, big soundstage and relaxed.

My set arrived yesterday, I have been listening for about 12 hours and I don’t see any good reason as to why I would want to send it back and get the FH3, especially as mine came with the balanced cable.

It is truly a fantastic piece of kit, I see no way in which portable audio could get much better, especially without spending a serious amount of money. I will be keeping this set indefinitely for use with my QP2R, I simply need the ifi IEmatch as there is a noticeable hiss

Congrats!

If you read my comparison between the FH3 and H40,

I came to the conclusion that they both have a similar frequency response. There are slight differences between the two sets which I went back and forth slightly preferring one or the other on various material. Either way, they both sound great despite their differences.

Would love hearing your in-depth thoughts after you’ve had the chance to listen to them more.

Anyone in the know care to speculate whether we’ll be seeing a H40 successor (“upgrade”) anytime soon (say, within next 6 months)?

anyone tried fixing the cable connector caps with loctite or superglue? would that be a good idea?

I received a pair of H40s with the 4.4mm balanced cable today and for now I am really disappointed by the sound.

I tested them with the Ifi Zen dac and my source was tidal.

For me they lack clarity, resolution as well as treble extension and the sound stage sounds very narrow to me.

I imagined they would have a more full bodied sound.

The v shape is really strong so they lack midrange and vocals.

Currently I have the memory foam tips on them.

Do these need a special dac to really shine ?

Because my listening experiences don’t really line up with the reviews here or on head-fi.

Try silicone tips. Foams butcher the treble a lot.

To piggy back on Rikudou’s suggestion, try Spinfit cp100 or Xelastec.

I don’t have the H40, but I think my Shozy 1.4 are tuned similarly on the low end. You could try reducing the 100-300 area by 2 db.

27

I also tried the green and red silicone Tips.

For me they sounded worse then the foam ones.

28

You might have gotten a bad fit with them.

If you get a good seal with silicone tips vs foams, the silicone will be better. And especially for iems that are already on the darker and bassier side. Foams reduce the treble more than usual and changes the overall sound a lot.

My suggestion would be these

Radius deep mount
Elecom ehp cap 20
JVC spiral dots/spiral dots++
Azla sedna earfit

I can’t get any of these here in germany except the jvc ones.

32

You might be able to import them from Amazon Japan. That’s how I bought them.

33

Ok which one of them should I get ?

34

All of them really. Especially if you are importing them from Japan, saves on shipping.

The jvc and azla are redundant with the deep mount tips though in terms of sound. But you never know if those wide bore tips fit you better. So I would recommend to at least get the Azla along with the elecom and radius tips.

Do be aware that the Azla tips are 1 size bigger than normal. So if you use large normally, you should go for ml azla tips.

You could also order the Final Audio Type E tips along with the rest of them as those tips are in my top 3 tips (type e, elecom and radius are my favorite tips). But the type E´s probably isnt a good match with the H40 since its already bassy (the type E reduces treble peaks and boosts the bass quantity and tightens it). But if you got other iems, the Type E is a great tip to have.
