Enhanced Sound with New-Generation Dynamic Driver

Moondrop has revamped the driver used in the original Chu IEMs, equipping the Chu II with a high-quality aluminum-magnesium alloy composite diaphragm dome and ultra-thin CCAW voice coil. This combination, along with the diaphragm's high rigidity and lightweight nature, delivers improved treble extensions and punchier bass response. The Chu II sets a new standard as the first budget IEM to incorporate an AL-Mg alloy composite diaphragm.

Anti-Oxidation Alloy Casted Shells

The Chu II retains the stylish design of its predecessor, featuring ear shells manufactured using Moondrop's advanced alloy casting technology. This manufacturing process ensures a robust and solid build structure with a refined textured finish. Additionally, the ergonomic shape of the ear shells guarantees a comfortable and secure fit, enhancing the overall listening experience.

CNC Machined Brass Acoustic Nozzle with Replaceable Mouth

The Chu II boasts a CNC machined brass acoustic nozzle, contributing to highly precise sound reproduction with a beautiful and rich tone. What's more, the filter at the mouth of the nozzle is replaceable, allowing users to easily swap it out if it gets damaged or blocked, ensuring uninterrupted audio performance.

Professional Tuning Adjustment

 The Moondrop Chu II is meticulously tuned by experienced acoustic engineers and audiophiles with extensive knowledge and experience in the audio industry. It follows the VDSF target response, just like the OG model, but with the inclusion of a newer and higher-quality dome diaphragm, resulting in refined and richer sound reproduction compared to its predecessor.

Clear Sound with Ultra-Low Nonlinear Distortion

 The Chu II offers an immersive listening experience with its clear and detailed sound reproduction. With non-linear full-frequency distortion measuring below 0.05%, the Chu II ensures high-quality output with a rich tone and exceptional separation, allowing listeners to hear every nuance and intricacy of their favorite music.

Detachable cable

The Moondrop Chu II provides users with the flexibility to customize their listening experience by allowing cable swapping. It utilizes standard 0.78mm two-pin connectors, enabling users to easily replace the included cable with their preferred upgrade cables or even switch to Bluetooth cables for added convenience. This versatility ensures compatibility with a wide range of cable options, empowering users to tailor their setup to their liking.

Moondrop Chu II

Very good for the price

Can‘t complain sound wise, given the price. The cable feels a bit cheap, but for less than 20, so you can‘t expect premium material quality.

Insane value

The value of the cable alone is worth more than the whole price of the IEM. As far as soft, lightweight straight cables go it doesn’t get much better than this.
The included soft case is awesome too, very simple and attractive.
The sound is matured and quite great, for some styles it really excels more than others. For example, i have had to take these out sometimes when the song i’m listening to has a guitar solo. Metallic or shrill frequencies around 4k can really jump out in styles of music where treble details are sustained for a period of time. It’s not like the tuning is necessarily off, but they are so dynamic within that frequency range that it can really take you by surprise. Those are the only moments these sound unpleasant to my ears. Almost all of the time they present music with a robust sense of clarity. They sound full and transparent in the lows and midrange might be my favorite. It never offends me and always sounds true to the source.
Having a metal shell that is so comfortable adds to the mystery of why these are even cheap at all. Even among the vast and growing variety of options at this low price point, the Chu II offers something great for reasons that extend beyond the sound quality. Definitely worth grabbing.

Great EDC headphones

I love the quality and clarity of these earphones. And it's comfortable for my ear in comparison to other IEMs. The best quality for the price. I changed a wire though!
Shipping perfectly fast, it took around two weeks to get it to Poland.

Good sound: period!

First let me say that it came from Linsoul to Croatia/Zagreb in less than a week and that is incredible!!!
And I'm listening to these whole day and they surprise me with clarity and wide stage, decent bass and mid bass, really good sounding in whole range, but, for my taste has a little to much treble, but, since I usually use EQ its not an issue at all..
I dont like talking about packaging or what you get with them, cos I never buy anything with that in mind, its like buying bread and admiring the bag it came in to, who cares, I only care for the product and is it good for me, am I satisfied with it, do I like it as it is? Simple and honest answer: YES!
I like that they are metal, I like the cable, tips fit me, great, high quality product, and it cost me just 19$..
And let me thank again Linsoul for excellent service, I'm already spreading words of how good you are..
