Sennheiser IE900 Review, Measurements, & Harman Target Talk
May 21, 2021 at 4:12 AM Post #361 of 4,902
Missing this hobby and world’s best forum for headfi. Unfortunately, this damn pandemic has me under virtual house arrest because of comorbidities and age. I miss my regular trips to HK and Singapore to buy the best and the latest. I also miss CanJam. This pause had an unexpected benefit. I m listening again to my older gear. Hopefully, once vaccinated and international borders are reopened, I can resume this hobby. There is always gold at the end of rainbow.

btt, I am looking forward to auditioning the IE 900 once it becomes available in my neck of the woods. In the meantime, I ll live vicariously by reading the reviews.
Its here in HK , so worth a demo.

I want to share some thoughts on the IE900 after almost two weeks of daily use. I’m sorry to say I’m not sufficiently technical to address in a way that many look for, as such, it will be a layman description with the knowledge I do have where possible. I am a music lover for many years (and once upon a time 90s DJ...) and up till last year, mostly listen via my separates systems and a variety of headphones and earphones - as of last November, I didn’t even know what a hybrid IEM was, let alone a single DD or an EST driver, they were all just earphones, headphones and some were Bluetooth (of which I've a few gathering dust)! My journey over the last few months with IEMs has certainly been obsessive, expensive and incredibly enjoyable - I’ve heard music in ways I’ve never before and I now rarely listen via my main system or full-size headphones. I admit to being a fan of Sennheiser and have had a few of their products over the years - HD-25-1 being a go-to back in my DJ days, HD650 (which I never use) in more recent years and a trusty set of IE8 that served me well for about 8 years, only actually finally retiring them last year as this hobby took hold. I’ve learnt a lot (but not enough) in the last few months and met many great likeminded music fans, I plan to continue this voyage of discovery and strive to be more proficient to articulate what I ‘hear’ into words that are useful to others… but for now, this is about as good as I can give!

Most home listening has been via the Sony NW-WM1A or Sony ZX507 for out and about portable use.

My recent IEM collection in order of purchase: XBA-N3, DUNU ZEN, DUNU SA6, Sony IER-M9, UM MEST MKII

First and foremost, I absolutely love the IE900 - right now, if I could only keep one of my IEMs, it would be this - mostly due to being the most solid all-rounder of any IEM I’ve heard in terms of its ability to handle any genre. In addition; the size, weight, form factor are perfect for any situation - walking, in bed, wandering about the house etc. I walk 5k every morning with my dog and I look forward to getting up at 6am to get these popped back in my ears - likewise during the day while working, finding moments to get lost in the music for a few minutes, even just while making my lunch or getting through some admin that doesn’t require much brainpower. I keep looking at others in my collection and thinking I must give them a shot, but then nah, IE900 it is…

IE900-IEM.jpg

Soundstage feels wide and natural, a well-positioned ‘stereo’ sound, instruments very well positioned and where I expect to find them relative to general listening experience of music over the years. The MEST MKII in comparison is somewhat wider but absolutely ‘taller’ too and much more 3D - this is good for some music but definitely not all - for example, I love it on well recorded ambient music, especially very cinematic albums - I’m not as keen with a lot of rock albums though, I find it can sound a bit unnatural at times, instruments a bit off in terms of positioning - a thought though in this regard, is it just I’m not used to hearing a delivery of this nature and need to get used to it?! But on MEST with genres that suit, that 3D tall and wide delivery is stunning and certainly a keeper in that regard.

In spite of the wide soundstage, I still feel a very centrally focused low-end delivery - I feel like the focus zone is in the middle of my head but separating out as appropriate for the instruments. I actually love how it ‘sits’ in my head, I really feel with kick drums for example that they thud in both ears perfectly to land a central delivery… reminds me of beat-matching kick drums back in the good old DJ days and I actually crave this position with other IEMs at times.

IE900- ZX507.jpg

Some of my test tracks had deep sub bass sitting alongside pounding kick drums - all wonderfully controlled and I keep wondering how the heck something so small is capable of this. I find the bass more obvious compared to the MEST MKII, not sure if its better per-say - I think going back to my reference to its position is where it shines - potentially a personal preference as opposed to one being better than the other.

The higher register of treble is an area that I tend to shy away from in music delivery - often choosing with audio system over the years to EQ bass up and treble down, probably the techno/house DJ in me. I’ve been concerned about this and look out for comments in reviews when considering purchases that might suggest an IEM is bright. Much to my surprise, yes the treble is more evident than I would expect to like, it feels like its fine-tuned marginally below a point where it could be an issue, but instead sounds wonderful and adds so much to a detailed, pristine and analytical delivery - I’ve yet to find it harsh on any music and again, often amazed how there is so much detail from a single driver.

There is a sense of being slightly recessed vs the MEST, a more forward centre on the MEST for sure which means for some vocal tracks, especially male vocals on the lower end of the scale that they can feel slightly back - not to the point that it bothers me personally but I do note at times.

The cable is excellent and very similar to the IER-M9, looks almost the exact same - slightly stiffer though and a small amount of microphonics if not correctly positioned around my ears and with the chin thing (what’s it called?!) - but easy to position and when out walking, I get zero cable feedback. The ear hooks are quite stiff and bend well around my ears - a slight concern here is when bending them over my ears, I wonder is this putting strain on the MMCX connectors that might damage over time?

The tips didn’t work out that well for me, I couldn’t get a good seal with any of the silicone tips and they sounded pretty poor as a result - I tried them first and was incredibly underwhelmed, bass was absolutely feeble as best. Switched to the included large foam tip and a whole new world opened - wow! I did ultimately switch to Comply TSX-500 in medium as I get an even better seal and no impact to SQ, unlike with some others where bass becomes way too much and overall too dark, not the case here at all - the TSX-500 seem to have a relatively medium bore size. Isolation is great - when walking, I can hear louder traffic but not enough to interrupt my listening, at home sitting in my kitchen as I am right now, I can’t hear any other noise in the house, including my wife talking to me… is it terrible to admit my frustration with having to unplug an IEM and ask my wife to say whatever she said again, only to find its a reminder I need to cut the grass or something? - she should know I have important listening to do.

They are hungry enough compared to the MEST MKII, on the Sony NW-WM1A, I need to crank up to the late 50s (out of 120) somewhere on high-gain, versus maybe early 40s on the MEST. Still plenty of room though.

Anyway, I would struggle to say whether I prefer the MEST to the IE900, they are both incredible IEMs in their own right but as noted, the IE900 would probably take the prize given how they can be a jack of all trades with any genre in any listening situation. I’m not exaggerating when I say they often take my breath away, I’ve stayed up way past my bedtime several nights over the last couple of weeks as I just want to keep listening, I’ve even broken my no wine during the week rule and had to pour a glass to accompany my listening bliss! They definitely complement each other well though and I will certainly be submerging myself in the MEST again soon for longer sessions.

They are unbelievably addictive and in my humble opinion, absolutely worth the price tag. Apologies again that I can’t address areas that a lot of folks here would like to know and I hope this was somewhat useful. I’m conscious there is a lot of interest in this IEM and I’m very lucky to have one before launch, as such keen to share what I can. Still early days too but I do feel comfortable at this point with my findings.

Thanks for sharing. I just bought the MEST MkII when I found out about IE900. Did wonder if I made the right purchase and was curious about the IE900. From your article though, sounds like I am not missing much, sounds like either is a great choice depending on preference. Wonder how IE900 would compare to something like Empire Odin or IEM much much more expensive.

This is absolutely a great write-up, you should be proud of how you were able to relate the tuning of the IE 900 to the music experience. It would be a shame to see this buried as the pages of this thread build up... please consider copying it to the IE 900 reviews section so people will always be able to easily find it!

Thank you, I thought of it more as 'thoughts' as opposed to a review as such but I guess it is!

People think reviews have to be this big formal thing... but I think you can just have fun with it! You can always edit later, but you had a lot of info to share and I think people would be interested. I’m all about encouraging people 👍

Edit: Also, congrats on getting a front page feature!

Yes exactly how I considered them, a formal process - I guess having gone to the trouble of writing what I did, good to give it a more permanent home.

I was very surprised to see that on the home page!

Did anybody order IE 900 from moon audio? My order has been removed from my order page but they already charged it and the listing is gone. What is going on?

The new Skee Mask sounds stunning on the IE900, brilliant production and complex programming all brought out beautifully.

Been wanting to buy this for the WM1A, but man it's a pricey album.

Yeah its a lot for digital but it's pretty much a double album. I'll probably go vinyl for this...

I've seen him DJ a few times and Compro was also an incredible album. Ilian Tape with the Zenker Brothers put out some great music.
