Great communication and fast shipping. Simple and straightforward transaction. Thank you!

Not sure I understand how the adapter helps the sound, but most importantly you like it and that is all that matters!

Can you shed more light your setup with the adapter? https://penonaudio.com/penon-os133-audio-adapter.html Is the adapter just a way to get your ISN H50 hooked up to your DAP or do you believe its improving the sound quality?

Anyone feel like the ISN H50's clarity doesn't peek through until you really crank the volume?

I couldn't sit tight any longer and removed the filter grill on the ISN H50 to check it out. Here is what I found... ISN H50 has no dampener screen behind the grill ISN H50 has sound tubes straight to the grill ISN H50 stock filter grilles do not seem to block or alter the sound at all So I...

I've been rocking the ISN H50 the last 2 weeks (connected to a Fiio LC-BT2 LDAC BT neckband). I still have my ISN H40s with modded grille filter replacements. I find the the sub-bass and bass to be significantly more refined and faster on ISN H50 vs the ISN H40. For the rest of the frequency...

Great communication, shipping, and packaging!

Found em, closing this out!

I love my ISN H40, but I have to try the new ISN H50! Willing to buy straight up, not sure what price what makes sense ... but the last two on here went for ~$225 I'm in the US and hope to keep it simple (buy and/or ship from the US as well). ------------------------ Related: I thought my...

I was finally able to get to this today. Grabbed filter grills that are less restrictive than the stock ISN H40 ones from an unused set of SoundMagic ES18 headphones and popped them in the ISN H40. Like @DynamicEars and others said...this is a great mod! I'm not one to claim sounds differences...

Have you ordered these specific ones for the ISNH40? I'm hearing from this thread I need 4.7mm size (and Penon themselves said that [https://penonaudio.com/5-pairs-of-in-ear-earphone-filter-grill.html] does not fit the ISN H40.

...4.7mm grills for the ISN H40s for the US? I'd prefer something shorter than shipping from overseas: I have no idea which of these are good bets: * Alixpress (with many options in the related products area) * ebay (had to scroll a while, maybe I'm not using the right search term) I'll go...

I recently picked up a pair of the ISN H40's used off on headfi forums. When I got them I saw they have a blue/purple color in natural daylight, and with indoor light/night time they look black. Every picture I see online shows the ISNH40 as black shells so I was very confused. Had to look at...

Yeah I thought the IT00 treble seemed a little forced in slightly the wrong frequency range personally too. Metallic or tinny was the word I used too, but not sibiliant by any means. It didn't go away for me after 50-100 hours of listening, but I loved the warm IT00 signature overall. I ended up...

I'm sticking with my Shozy Form 1.1 over the ZAX, but I had 100% the same feeling and this is an important distinction. I REALLY liked the ZAX for lower volume listening (music and podcasts too). I was thinking this earlier, but personally I think it would be really cool if an EQ adjusted based...

Personally I found the ZAX more neutralish, bright, and airy than the Tin T2+. Can't comment on the Tin T2

Yeah if I were to do TWS style, I would do something like the TRNBT20. These little ear batteries are so small that once they start losing capacity they will be useless quick. Personally, I went with the Fiio LC-BT2 neckband + Fiio FH3 for my desk because it has ridiculous ~20hr battery, a...

I found the ZAX to be pretty comfortable. Lightweight and the stock large size tips gave me a good seal at medium insertion depth (didn't need to jam them in my ears). Seems like they would stick in even while moving/light exercise.

Used the stock cable, then also used the Shozy Form 1.1 all copper cable. Didn't notice a difference. I used some microtape to half cover the nozzle filter. Definitely helped take out some of the extra energy in the treble a little bit, but in the end its personal preference for me - I like my...

Just got the KZ ZAX today, initial impressions... (+) The treble peak and forwardness makes them feel airy and open, and has a wide sound stage. Its a pretty lively listen overall. (+) The bass is pretty controlled but has presence when called for. Its fast, not bloated, doesn't bleed into the...

Got a chance to try everything on my list except the KZ ZAX. Surprisingly, the Shozy Form 1.1 are the clear winner for my taste so far. (my thoughts on them here) I personally found the 1.1's to be a nice blend of the FH3's treble and detail with the bass impact and warm vocals and mids of the...
