    They better not retune the IT01s then, as they are just right as they are.

    I like my early 2018 IT01 just as it is. I have the black one. Why did yours need replacing? Did they announce that it was retuned?

    I don't know whether an official retune has taken place but the nozzles look different...look like screwed on... [https://www.audioreviews.org/ibasso-it01-photography/] and the frequency is different in the midrange. I measured several times over and also have good channel balance confirming the accuracy within my setup.

    From memory, there was not much difference in sound: bass stayed the same and the mids were sharper/pseudo-clearer. Adding upper harmonics to the lower midrange may not be outright audible but may cause fatigue to some.

    I sent a few questions to iBasso...

    My original IT01 had given up in one earpiece...driver flex [I honestly have no clue what caused it]?

    I hope that driver flex does not kill drivers... some say it does... some say not. I have it in my TFZ Exclusive 3... no matter how carefully I put them in and no matter what tips I try. Because I had never experienced it before I got the TFZ, I thought the silicone ws making that sound but now I do not think that is the case. It would be impossible to find a replacement... pretty sure I got the last one in the world... after it was discontinued.

    Thanks alot for the alert! I do like my oxygen alot but I feel the male vocals are full and clear without that nice power the kpe produce. However, the kpe vocals are slightly recessed for me which is no good either. I love the technical abilities of both these iems but am looking for an upgrade now.

    Try micropore tape, covering the nozzle by 80-90%...or cover the whole nozzle and poke a hole near the side...and a second one opposite if needed. This could/should tame the upper midrange and treble...results vary.

    iBasso told me that did not change the frequency response and that the filters can now be removed. They speculated that I did my measurements with clogged filters, hence the difference. My measurements were done ootb...maybe the nozzle length has changed.

    here is a FR response of my very bright sounding Sabaj DA3 dac (the reason why i don't like the amazing sounding for the price NX7)

    Those two with the switches are Tansio iems I presume? Any idea on the new TSMR5, I see it's going for $500 on Penon Audio.

    They're the TSMR-3 Pro and the LZ Big Dipper.

    The TSMR-5 is $419 and TSMR-6 is $529.
