Sony IER-M9

These have been the most comfortable IEMs I've ever worn. Light weight and a great fit, I find myself forgetting that I even have them in at times. I'm not the most qualified to speak on their sound as I have not had enough experience in this caliber of IEMs, but much like the fit, they are not fatiguing. I can wear these for hours comfortably.

I love these IEMs. Definitely worth the asking price. The packaging feels very premium and the IEMs sound amazing. I pair them with the ZX507 on the balanced output and they really make the music come alive.

Wow! Thanks Jenny.
Crutchfield customer from San Diego, CA on 3/7/2021
Wow! I finally hear the depth and expansive soundstsage of Hi-Fi music. I've tried the cheap in ear monitors and no matter how many drivers they claim to have the sound was harsh, gritty, and quite unpleasant. Sony is correct to supply eight different sizes of ear buds because proper fit is essential to hear the magic. I use a different size in right vs left ear and have that perfect fit (=sound). Sony also supplied the standard 3.5mm RCA cables and a set of 4.4mm balanced cables which came in to play when I added the Walkman NW-ZX507 which has a balanced port. (That' a whole other Wow!) Thanks to advisor Jenny for the chat session that lead me through this great Crutchfield experience.
Pros: Expansive, detailed sound Large selection of earbuds to nail the fit 3.5mm and balanced 4.4mm cables suppled Silicon cable - reduces tangle anger 90 degree jacks
Cons: I thought about this for a while. Maybe price. I think its worth it. Requires a break in period.

Nice earbuds
Crutchfield customer from Watertown, MA on 12/17/2020
Nice, quality sound and good comfort. With recent price cuts, IER-M9 is a better value than it was originally. Slots between the IER-M7 and IER-Z1R in price, which frankly is why I chose it.

Once you find the right ear tips, you'll notice a healthy bass response. It is always present, and even impactful when the track calls for it, but it isn't boosted to a level that makes these overly unbalanced or messy. Any more and the presentation would feel overly colored, but this means there are more fun headphones I've listened to. Bass guitar in songs is easy to find and separate from drums. Vocals are detailed and textured to a degree that I didn't think was possible. It's a whole new degree of livelihood in the singer's voices I can pick up on. But on some tracks, female vocals can sit ever so slightly too far back for me to properly enjoy them, hiding between cymbals and guitars. There is precisely the right amount of treble response. Any more and cymbals would start sounding hot and cheap, and crowding up the rest of the mix. Any less and I feel like the micro-details would be lost. M9's greatest strength lies in its details. The tiniest echoes and weakest reverb are noticeable. Not boosted, but present. Easily detectable, even if you aren't giving them your full attention. These headphones finally let me listen to poorly recorded music and enjoy it like I could beautifully-mastered music. They're so, so forgiving. I can only describe the presentation as dreamlike, and this can and this can be disorienting. I feel like I'm floating in space with nothing but sound by sound gently placed around me. It gives me shivers. I feel transported. 5/6.
Pros: - Extremely detailed - Great Separation - Great Bass - Great Lower Mids - Great Treble
Cons: - Upper Mids Lacking - Tips could fit better - Dreamlike quality to the sound
