YU9 Audio QUE

This IEM is the type of sound I've been looking for since I got in the IEM hobby in 2017. I've spent 1000's of dollars looking for that perfect IEM.

I've been an audiophile since childhood. I get it from my mom and dad who love music and have huge collections of vynil and some of the best sound systems money could buy from the 80's, 90's till today.

This is a magical IEM. If you've not heard a bunch of IEMs before, you will not understand what this IEM is doing so well.

The bass is perfect and gets visceral on high gain mode, mids are perfect and very realistic, Treble is super refined (S+) very detailed and the most extended I've ever heard. (credit the wideband custom Knowles tweeter).

Coherency on this IEM is S+ tier. Anymore bass and it'd interfere with mid clarity and technicalities.

It's basically Neutral with a tiny bass boost but the bass is more than you see on the FR graph. it goes really low into the 30Hz and that's satisfactory to me.

The treble magically manages to never ever offend in anyway despite being very extended beyond human hearing (Stock AET07 tips only)

The imaging is so pinpoint that on live albums, you get transported to the venue.

You can clearly pinpoint which side of the room, and row a sigh came from, laughter etc. wow!

Things just pop out of nowhere on this IEM. It plays you back the track as it was recorded but, in a way, you've never heard before.

This IEM is definitely a benchmark regardless of price.

QUE immerses you into a 4D space inside the music. it's such a soulful, musical, technical Elite IEM. You will feel on top of the world with this IEM.

In my stable is QDC Anole VX, Monarch, Symphonium Audio Meteor, Mest MKI and MKII etc. Mesk MKII has been my daily but now it sounds flat and unimpressive. Everything is going on sale and I'm buying a backup YU9 QUE.

Stock AET07 IEMs bring out the best of this IEM's magic.
Medium size is what I used on first listen but noticed the seal wasn't tight.

Switching to Large created the perfect seal and the sound just took me on a spiritual journey into my music. your library will sound like you went up a dimension.

I tried many ear tips from Spin fit, JVC, etc. and they downgrade the sound and listening experience. Stick to the AET07. These guys clearly know what they're doing.

I'm out of the game for now until something that adds to this type of tuning, coherency, technicalities and 4D space shows up.

Excellent IEM regardless of price. I own a couple of significantly more expensive earphones and this one keeps up with them with no problems. They also sound better than my other IEMs in the same $400.00 price range. Excellent treble, vibrant mids, solid bass, it's all there. They fit my ears just fine. The included sticky tips work great to keep them in. Overall this is a winner.

I adore this iem and was blown away by the shipping time. My only complaint is that I received the 3.5mm version and not the 4.4mm that was ordered. While this is a non-issue for the most part especially since I ordered the upgrade cable, it is nonetheless a little annoying. Besides the cable quibble this is an excellent iem which would be right at home with kilobuck iems.

Great sounding bass that slams hard and digs deep. Excellent midrange and treble response. Open and spacious soundstage. Good resolution and detail. Good feel to the cable. Everything you throw at it sounds right. Very comfortable to wear for extended listening.

Very well tuned, impressive low end especially sub bass, mids, highs are also a stand out, can't fault any part especially at this price.
