## 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!

**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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Has more details in the music
*by L***H on December 25, 2021*

Disclaimer: I am not an audiophile, musician, or sound engineer. My review is for general users.Received on December 23rd. Have been using for only two days.I have been using Shure e2c (e2c) for all these years. Since Apple Music has introduced Hi-Res Lossless music, I want to fully experience the marvel. After debating between Shure SE865 (865) and Sony IER-M9 (M9), I decide to get M9. M9 provides both balanced 4.4 mm and unbalanced 3.5 mm ends. At a similar price, M9 has one more driver than 865. For DAC, I use THX Onyx for its portability.I completely understand that it is unfair to compare e2c with M9, but that is what I have. I have a low-end Asus Cerberus gaming headphone and Apple EarPods with lightning connector, but they are a lot worse than Shure e2c. I also have Airpods Pro, but all bluetooth earbuds are lossy.When I use e2c and M9 to listen to the same lossless music, some instruments that I did not notice before with e2c become more obvious with M9. In other words, M9 provides more details in the music.M9 has stronger treble and bass than e2c for sure.M9 has a higher quality cable than e2c.M9 is much more expensive than e2c.Both e2c and M9 have strong mids.Both are comfortable to wear for a long time.Both have a similar level of noise-attenuation from external environment.E2c is louder than M9 with the same volume setting.Ironically, when I listen to another lossless music with M9/THX Onyx vs the default, build-in speakers of my MacBook Pro (16 inch, 2019), I can hear more details with the default speakers (set at 24 bits, 96 kHz) than M9/THX Onyx (set at 24 bits, 192 kHz). For example, I can hear the unintentional background noise in the studio during recording with the build-in speakers but not with M9/THX Onyx. When the musician slides his fingers on the strings of a guitar, the sliding is also more pronounced with the build-in speakers than M9/THX Onyx. Perhaps THX Onyx filters out some details?I then unplug M9 from THX Onyx and plug M9 directly to the 3.5 mm audio out (set at 24 bits, 96 kHz) on my MacBook Pro and got similar results. The default, build-in speakers of my MacBook Pro still provide more details than M9. Perhaps the 3.5 mm audio out loses some details?Just to be fair with M9, the bass of M9 is stronger than the build-in speakers.Lastly, I plug M9/THX Onyx to my iPhone. Yes, I have a lightning to USB camera adapter from Apple. THX Onyx LED changes color according to the sampling rate of different songs. M9/THX Onyx performs similarly as the two forementioned conditions.Bias: after spending a grand on M9, I feel obligated to give M9 five stars for every category on Amazon review.

### ⭐⭐⭐⭐⭐ An excellent top of the line IEM
*by F***F on February 18, 2021*

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.
