Review: An excellent top of the line IEM - These IEMS hit all the right spots for me. They have top notch technical capabilities in separation, layering, and resolution, audio reproduction with natural timbre, and a warm-neutral sound signature. Together, these allow the IER-M9s to produce a supremely enjoyable and exquisite listening experience across all genres. Concerning comfort, the preformed ear-hangers and the provided different sized ear-tips keep the IEMs stably perched in my ears with no difficulties. The connection between the cable and the IEM body can swivel, so there should be no issues with awkwardness of positioning of the IEMs. I have found it easy to quickly put on the IEMs and get a good seal (common advice is to pull the lobes of the ears backwards and upwards slightly). These also provide good isolation, having used them on flights (yes, you can't really experience 'audiophile' quality music on a plane, but from experience, they're definitely still significantly better than the Sony WH-1000XM4s and Bose NC700s). For reference, I own the IER-M9s and the Focal Clears (a pair of over-the-ear headphones), and I use them for about ~20h and ~40h a week, respectively, switching to the M9s during the evenings when I typically prefer a warmer sound signature or when I wish to read in bed. These are the priciest personal audio devices I have ever owned (but not the priciest that I have tried), and I have no regrets for either of them. I should point out that I am not too concerned with large soundstages in my devices as I have used IEMs and headphones with larger soundstages in the past and found that I was not impressed with what they did to my music with the exception of orchestral pieces. The M9s also produce a palpable and pleasant rumbling in the sub-bass frequencies (with no strange balanced armature flavoring that I can discern), though they are not considered bass-heavy when compared to other top of the line IEMs. NB: Some readers may not consider the IER-M9s "top of the line". Apologies for the abuse of language.
Review: Hear details you never noticed before! - Hearing my favorite songs through these "in-ear monitors" is a revelation for someone like me, accustomed to good but still mass-market headphones (price range: several hundred dollars). I hear instrumental details that I never discerned in 35 years of listening to some songs, first on vinyl or tape, and now in a CD-quality lossless format, with a variety of amplifiers and headphones. This is to say that I know the music well and find new pleasure in listening to it with these monitors. When you get the sizes right, the ear tips block most outside noise, making these monitors suitable for use even in public environments. An interruption-free listening session is best, because putting these on just right takes time. They're not like ordinary earbuds, which can be pushed in and pulled out quickly. The cables are of just the right length, and they don't tangle. The storage solution is overdesigned, requiring you to coil the cable around your fingers, squeeze the plastic holder, slip in the coiled cable, push in the monitors, and slide them down into the keyhole positions. If you look closely at that last page of the manual, the monitors are drawn backwards in the holder. It would not be possible to orient the ear hangers as shown, unless you turned the MMCX plugs each time you put the monitors away, and turned them back before listening. Dispensing with the clumsy plastic holder, laying the coiled cable in the case, laying the monitors on top of the cable, and closing the lid, seems to work just fine. Last but not least, it's preposterous that Sony provides only a 1-year warranty for a product as expensive as this. I haven't tried the balanced cable, but results with the conventional cable, using either my Sony digital music player or my Oppo headphone amplifier, are excellent.

## Questions & Answers

**Q: Can the sony ier-m9 work with a windows pc using the 3.5 mm connection? would i need other hardware? will there be any audio quality loss if yes?**
A: If you want to use PC as source, I recommend you to buy the RME-ADI 2 FS or Chord Mojo 2. Your PC will send digital signal without noise to Mojo2 or RME and it converts the digital to analog signal cleanly. 
If you plug the headphone directly to 3.5mm, it will tap into the noise from the PC and the 3.5mm does not have enough current to drive the full potential of headphone. You will lose details.

**Q: (sound wise) how does these compare to "wf1000xm4“ or "wh1000xm4" (want quality "branded" wired earbuds everyday use) ?**
A: The sound quality of the IER-M9 is miles ahead. The details, instrument separation, timbre, soundstage and dynamics are simply far better.

**Q: Can these be moved with just an iPhone?**
A: Hi Carlos,

Thank you so much for your interest in our IER-M9 In-ear monitor headphones. If your iPhone supports stereo mini-plug (3.5 mm) connection, yes, it will work.

Thanks again for considering Sony!

- Romeo

**Q: Are these sweat and dust resistant?**
A: I have sweat with these while playing the drums.  I have had no issues.  As far as dust resistant.  I do not know of any headphone/ear-monitor that has ever succumb to dust.  I keep them in the case anyway.  I hope that helps.
