There's a guy on UK eBay selling the MH750 with a re-cable inc. mic. I've bought a pair from him and they are genuine. https://www.ebay.co.uk/itm/274656170970?hash=item3ff2c893da:g:9TAAAOSw3FFgA1m8

I believe so, yes. Although you could probably pick up a descent used iPhone for less than a new iPod.

I'm not really up to all this stuff so can't answer your question personally, but I did watch a video recently that seams to be discussing this very question - hopefully this helps.

My problem wasn't the filter in the sound tube being clogged up, but the area around the outside and behind the tube that meets the metal section. Im presuming there is some sort of vent there that was clogged and causing the problem?

Has the driver stopped working completely? About a month ago the right driver on mine went really quiet, probably about 10/20% volume, I used a small brush and gave it a good clean (even though it looked fine) and it came back to life - it's been working fine ever since. I have purchased a...

Is it because you're using a - (minus) and not a – (tilde)?

Are you using v23? When I updated my A55 a few weeks ago, I downloaded and used v25, so you may be typing in the wrong 'v' number.

I have the same problem regarding most tips not being big enough. Although, I seem to be the opposite to you, as wide bores like the Spiral Dots boost bass performance to my ears. Have you tried Slater's 'Flip Tip' mod with the Final LL tips - I can get a good seal doing this (and it works...

Hopefully! Can't wait to try them when they arrive. Already have some Spiral Dots, so will give them a go too. Thanks.

That's good to hear - I've just ordered a pair of E5000's to use with my N5ii

I push them down the nozzle as far as they'll go, yeh. Although I do use the large size (big ear'oles), so there may be a bit of difference...

Well everyones ears are different I guess - I've been using these tips for a while now on mine and think they sound fantastic.

Excellent news - glad you're enjoying them! Strange about those o-rings though, can't say I've noticed any with mine. I've just opened up all the bags of tips from mine as I've never even tried them before, no o-rings in there. Maybe worth asking in the T01 thread, Paul from iBasso often...

I tend to listen to a lot of downtempo electronic music that doesn't have a huge amount of vocals so wouldn't be the best to comment on that front. These are certainly a fun sounding IEM though, bass is big whilst tight and controlled. The detail, soundstage and imaging are better than anything...

Not sure what you intend to use them with but I get no hiss at all from my IT01's when used straight out of an iPhone SE or the little Shanling M0 DAP - They sound fantastic.
