M9 is definitely not on the same league as the HE-1 in any technical department but the overall sound signature is terrifically close.

Exactly what I feel about the HE-1! I wasn't satisfied with the HE-1 soundstage which is rather...narrow, I expected it to wow me by its wideness when in reality, it was a bit disapointed to be honest. Given that the lower end HD series don't sound that wide and that I was mostly impressed by...

I managed to have a demo session with the HE-1 and its overall sound signature is surprisingly similar to the M9! Such a bold claim! I get it, given that I only had 1 hour with the German Luxury but what had been stuck in my head me for the past week after saying goodbye to the HE-1 is how close...

Tks for your fast reply, I really appreciate it.

@Virtu Fortuna Would you mind sharing more detailed impressions with your M9? You've been reviewing lots of IEMs, where would you put the M9 at your personal ranking list, could it even make it to the top 3 or 5 and the best source you've paired with your M9?

This is the first time I see a cable sleeve ungluing with the IER series. With that said, degraded earhooks that eventually become sticky and teared apart is almost a known fact with the IER series cables.

Do you consider doing a review of the M9 on Headfonia? If yes, I'm eager to see it, I've been reading Heafonia reviews for years and always wonder why there aren't any Sony signature reviews on the site.

Have anybody used Mojo/Mojo 2 as a Dac connected to the G5 as an amp? Could you give me some impressions on the combo? I heard that the Mojo 2 is excellent as used as a standalone Dac and since the amp section of the G5 is also exceptional within its category, is it worth it to have a bulky...

Totally agree, the M9 is the best of its kind. It needs time and experience to be able to fully appreciate it but once you understand it, its vert hard to ignore the IEM, it doesn't excel in any particular area but it does everything so on point that others just sound a bit off here and there...

I owned the U12T and would choose the M9 over the U12T any day/every time! The U12T sounds bland, thin, sibilance next to the M9. The M9 would absolutely destroy the U12T in details (later), imaging, separation, imaging, timbre, image broadness, bass size, cohesion, vocal weight and focus...

Actually, not only the Z1R but the whole IER series still remains competitive these days. I prefer the Z1R and the M9 to U12T, VE Phoenix, Tia Trio,...

This is exactly what I like about them, affordable and collectible. Thank for your super detailed impression! I really appreciate it. I see these peaks very often with monitors, the whole JH audio lineup have an unaturally boosted peaks at around 6k regions. Live engineers seem to rely on this...

Thank you for your lightning quick impressions, which further heightens my desire to get a pair of EX800sts.

Wah, I didn't know that the Z5 is still on production, after becoming a Sony fanboy, its super tempting to collect not only currently on sale products but also the ones in the past, especially, those weird but interesting designs from Sony. I'm going to put the Z5 and EX800st on my radar to fill...

I'm eager to see your comparison, wish you have good quality time with your second M9s :gs1000smile:.

What makes me want to re-acquire the Z1R is due to the miss for its intense but fun and addictive bass response as well as its brighter and more energetic treble, not to mention the Z1R's second renowned feat, its soundstage which is quite unique in my experience. I think getting a used pair of...

I've seen several people sold their M9s only to buy them back, the same with the Z1Rs as I'm considering re-acquire a pair, the IER series is legendary! I see you're currently having the Trifecta,Legend X and Penon Impact, would you mind do a comparison between those 2 TOTLs to the M9s.

It seems like Z1R is only discontinued in some EU countries since they're still listed for sale in some Asia countries like Singapore, Vietnam, Japan,... BTW, a prior notice of a discontinue would actually intensify my desire to acquire one even further. I made a mistake selling a pair, If I...

No, they are completely different in the mids, the mids on the M9 are closer to your face with bigger image, more impactful and detailed. On the other hand, the mids on the Z1R are pushed back behind the bass and treble, they sound distant, thin and recessed. With that said, it depends on the...

Hmm, could this be a sign that Sony is going to release successors to the IER series, or probably to the Z1R only :thinking:

Great, I think you would have quality time with the Topping.

Definitely worth it if you want to swap cables. The MMCX on the Z1R is super tight, one of the tightest I've came across, it won't move unless you rotate it. About the upgrading accessories, just find a pair of tips that let you wear the Z1R securely. The original cable is also highly praised...
