An Entry-Level Killer Set

Moondrop has years of experience in tuning and creating single dynamic driver earphones. The latest CHU is designed to be an entry-level killer set with exceptional clarity and performance. It complements different genres of music well with its nicely detailed and lively tuning.

10mm Composite Diaphragm Dynamic Driver

Moondrop has equipped the CHU with a Nano-Crystal Coating Composite Diaphragm Driver unit. The high-performance composite cavity with high-frequency phased waveguide leverages a N52 Nd magnet internal magnetic circuit and 0.035m ultra-thin imported CCAW sound coil to obtain high energy conversion efficiency, and deliver outstanding performance with full dynamic range and rich details.

Accurate Calculatioof Acoustic Coupling Cavity

In order to match the frequency response as closely as possible to the VDSF Target Response, the acoustic coupling cavity needs to be carefully controlled. Through volume and dimension calculation, FEA finite element simulation and 3D printing experiment verification, an acoustic coupling cavity has been created which can accurately reproduce the ideal frequency response.

Premium Moondrop Spring Tips

The package of Moondrop Chu earphones includes their latest launched Spring ear tips. These are premium silicone ear tips that are known to provide a super comfy wearing experience for the users.

Ergonomic Design

As a earphone brand, we’ve been collecting lots of data and making improvements on the design. Combined with excellent ergonomic design, it will not feel uncomfortable to listen to music for a long time.

One of my favorites

I was looking a decent pair of IEM for using them when outside home. CHU did deliver a great performance on sound (music and calls) 5/5 for me especially in this price range.

Good everything, except cable

Everything on the Chus is amazing. The sound is nice and neutral and the fit it pretty nice, however, the cable is disappointing. The non-detachable cable is fine but the stiffness and kinkyness of the cable is a hassle. It's hard to wrap it and it can be annoying. I also had to use the silicone ear hooks because without them, the cable would not stay over my ear. However, everything else on the Chus is great! The neutral sound is nice, but some percussion noises can be a bit harsh, but over all, good soundstage. The build quality is also really nice (excluding the cable). The main selling point, however, are the eartips. with the Chus, you get Moondrop's springtips (12 bucks on their own). These are great and definitely better than moondrop's old stock tips. Overall, although the cable isn't the best, this is definitely worth the buy, but mainly for the tips.

Amazing Neutral

The mids sound correct, overall amazing as heck.

Very good

Great neutral sound. Not very comfortable for me because the cable won't stay in place and no detachable cable. I find the 7HZ Salnotes Zero better for the same price and detachable cable. The Moondrop chu has better tips, it's a good deal for the price of the tips alone.

Extremely satisfied

I had several iems. Chu are my favourite, I always smile listening to them, they do all week dynamics are ok voices are comunicative bass is enough, just listen to the inner soul of the music at a ridiculous price. I don't find them fatiguing in the highs at all the sound is warm with the correct energy in the highs as in the real life, I'm a musician. The little metallicity you can feel at the beginning disappeared with the burn in. I used with different tips, narrower bore, to increase bass, and the cable noise is a problem only if you run with them, but better then etymotic.but for this problem they give you removable plastic arch to fix the cable over your ears. I'm curious about 7hz SALNOTEs zero now but Chu is a must have for me.

Shipping FAQ

Which countries do you ship to?

We are generally able to ship to most countries via Express Shipping, and many countries via Standard Shipping. You may clarify this with our team to check whether Standard Shipping is available to your country.

We cannot ship to addresses that are "PO boxes or APO/FPO".

*Note: Generally, we can only do Selected Shipping to India and Russia. We can only do Express Shipping to Africa, Argentina, Hawaii, Kuwait, Mauritius, Montenegro and Sri Lanka, to name a few.
This may be subjected to changes due to unpredictable issues such as Covid, war, and etc.

How much does shipping cost?

We have two shipping methods - Standard Shipping and Express Shipping.

Standard Shipping is free for most countries, while Express Shipping is 15-35USD depending on your country. If your order is over 270USD, Express Shipping is free*. 

*This applies for most countries. However, large items such as headphones and desktop DAC/AMPs (e.g. HarmonicDyne G200, MUSICIAN MDP-2, and etc.) are excluded.

Shipping fees exclude import taxes or processing fees that may be applicable for your country. Linsoul is not responsible for such fees. Should you refuse to pay the tax/customs fees, shipping fees will still be deducted from the amount paid for the two-way freight charges. The cost of the freight charges may be more than the amount reflected on your order due to tax and other miscellaneous fees.

Some parcels claimed to be “returned to the seller” may be destroyed by the post office or customs officers when buyers refuse to accept their parcels or fail to pay for their taxes. No refund will be processed for such cases.

Standard Shipping via YunExpress is a tax-inclusive option for some countries. However, Linsoul will not be responsible for additional administrative or handling fees charged by your local courier company or customs. Please kindly check this with your local customs.

For certain remote areas, there may be additional charges via Express Shipping. We will contact you if there is a need to make additional payments. 
Please contact us before placing an order, should you have any queries regarding shipping.  

How long does it take to receive the order after it is placed?

For in-stock products, your order will be shipped within 3 working days. You may check with our staff regarding the in-stock status of any products. 

Customized items will take a longer time. Please contact our staff for more information.

On normal non-sale days, once your parcel has been shipped out:

  • For Standard Shipping, it takes about 2-4 weeks for items to be delivered after shipping out. For some countries, it might take up to 2-3 months, depending on your country, its customs and other factors.* The duration for transit is something beyond our control. Linsoul will not be making refunds for such cases. Please consider an upgrade to Express Shipping or keep the waiting time in mind.
  • For Express Shipping, it takes about 3-7 days for items to be delivered after shipping out.

*Note: Timings might be affected due to festive seasons or other unforeseen circumstances

    • Wrong address or phone number provided by recipient
