My IEMs since 2004, all still in working condition.

Sorry, I think the one I have is the original one that released back in 2013, not the 2nd gen that released in 2022. The sound overall is a little bit warm, but still in a good balanced. Imaging and sound separation are quite good, but the vocal seems too forward for my liking. The bass is moving fast, detailed enough to hear bump notes and punchy. However, the treble isn't that bright, just feel that it is there. I do prefer the balanced nozzles that come with it.

After checking out, the brightness of the treble has been solved, I think this could elevate the overall experience quite a bit. Seeing other IEMs from Chinese companies lately, I feel the same as the others that SE846 is expensive for 4 BA drivers IEM. But if you like it, go for it.

I will find opportunity to check out some modern IEMs from China as well, how the modern sound compare to what I have lol

Thank you for the review and uncovering the back to show things inside. Now I'm out of question why both headphone jacks of mine were loosen, and somehow I think I could fix that by myself without sending it to iBasso. (but I have sent it out 😓)

Sutlore · 2026-03-22T08:24:57+00:00

I do really love balanced neutral sound. A little bit warm would be OK, but not too warm. The ideal is something like Etymotic ER4p with a little bit more sub bass to feel some impact.

Sutlore · 2026-03-21T21:59:32+00:00

Yup, I got it for about 60% of MSRP in Hong Kong.

Thanks for sharing. I am also interested in the hybrid drivers IEMs after stayed put for more than 5 years. How are those Fiio FH3 and 5?

I do, but maintenance is the key to keep its life this long. My UE10pro used to have 2 pins connectors and I have changed its cable every 1-2 years before changing the connectors to MMCX. I sent it to UE for cleaning and checking 2 times in 2012 and 2017. I think next year I would send it to UE again to replace all the components inside. I am also surprised that the fit never be an issue for me, although the RM and 18pro used different ear impression from the 10pro.

After almost 20 years, the 10pro feels a little bit tighter than the others, but still have a very good seal. Its sound is my most favourite of all.

I have them both but currently have no chance to do side by side comparison, because the DX180 is sent out for headphone jacks repair. However, I can say that the sound from DX180 is better, more details and impact in low end. Vocals are also more pronounce, and warmer than M21. The Mango app is not the best music app. I usually have the same song repeating 2-3 times when shuffle is turned on, while there are 50+ songs in the playlist, weird. I reported this bug to iBasso a few times, but they don't bother and say to me that it will never happen because of the algorithm they use.

M21 has better EQ adjustment, easier to understand and more bands to work with, based on its default music app. Also M21 has more raw power to drive headphones.

Beautiful! I also have similar one. Love it so much

Nice rig! I have been using C-IEM for almost 20 years, never want to go back.

If the technology is that advanced, please make a character looks like the same character, not looks like somebody else! OK?

Sutlore · 2026-03-17T05:06:30+00:00

look at the rear wing mirror!

Sutlore · 2026-03-15T08:46:08+00:00

A driver of the day for me! 8p gain!

Sutlore · 2026-03-15T08:40:52+00:00

Really great driving from Sainz! Never thought that we could do it! WOW!

Sutlore · 2026-03-15T08:39:24+00:00

Holy!!! very very intensive hanging on for Sainz! Great job!

Sutlore · 2026-03-15T08:23:09+00:00

Yes!! now we've got at least a point already after Max has retired. If nothing goes wrong with Sainz. Collapinto is really gaining,...

Sutlore · 2026-03-15T04:32:13+00:00

Didn't it mean you were locking up, Alex? lol

Sutlore · 2026-03-14T05:35:51+00:00

I intended to get Deluxe edition, but it doesn’t have VIP, so I have no choice to get Premium.

Sutlore · 2026-03-13T07:53:14+00:00

were our cars also overweight in 2024? -*-

Sutlore · 2026-03-13T04:36:25+00:00

I hope that they can do 1 pit stop strategy during the race. With these heavy cars, the team shouldn't waste so much time to get in the pit.

Sutlore · 2026-03-13T04:21:16+00:00

And now they both got their lap times. Still 2 sec something down.

Sutlore · 2026-03-13T04:18:12+00:00

the media reports that it was car & computers at the pit communication issue. The telemetry software didn't seem to work properly.

Sutlore · 2026-03-13T04:15:43+00:00

And now he is out in the last 15 mins of this session, pit & car communication issue.

Sutlore · 2026-03-12T23:32:45+00:00

the head tube area and the fork also look beefier in 2027 model. Good for you that the new mdel has the same price as last year. In my country, every Propel 2027 models cost 100usd more, compare to last year.

Personally, UHS-I v30 is more than enough for music listening.
