Great product overall, shipped really fast. The tune is also pretty good for its price. in terms of feel, it may start to hurt small ears around the earlobe depending on how you wear it but yeah.

Wonderful little budget single DD IEM!

I think as far as an introduction to the hobby, there are few IEMs I would suggest over the Chu 2 DSP. There's a lot to love about the sound, but I think the simplicity of the DSP cable and applying an EQ from the app elevates the experience. I would say the tune out of the box is warmer than it is bright but you can select one of the options in the app to change the graph significantly. While new users may not want to do this right away, having the option to grow into makes these a stellar first choice for an IEM in my opinion. The tips and cable provided are honestly fine by my standards, but tip rolling is highly suggested as everyone's ear is different. I have many higher end IEMs that I would honestly say these are not *much* worse than. These certainly do well at their price range, and can provide a complete experience without the need of a dac or any 3rd party tips/cable adjustments.

Pretty good for the price

So I’ve had mine for over a week now and used them daily. I can say that they’re pretty good at their price range, but I’m only talking about the buds/drivers here, because the CDSL cable is pretty bad. Main issues are popping and frequency issues. Pops appear out of nowhere just after plugging the cable and I have to unplug it and sometimes I have to repeat the process for several times to get the pops to stop. I know it’s the cable because I have tried the products separately. The cable has the same problem with any other IEM that I have ( TRN MT5, Qingluan Z4 and other ) while the buds don’t seem to any problem at all. I love the buds, they are very slick and offer a nice sound. I’m just disappointed with my cable and that’s it.

Great Headphones, meh cable

Great Sound quality and clear. Cant go wrong with them since they are really good for this price. You can even use the cable for other 2 pin IEM. 2 Stars less because the cable somehow got broken in a few months so be careful with that. But cleared it up with Linsoul support. Overall good IEM for even better Pricing.

Amazing pragmatic device

This is like 2 in 1 - pretty good tuning without the cable but the cable can bring it to another level and the cable can be used with other iem improving them

Dac/Amp is nearly as excellent as the Chu

With Feaulle H570 tips this is better than the champion ~100$ headphones with perfect desktop dac/amp at both music and gaming.
I have to 3% peroxide wash the removable filters of vapor deposited wax after a month and a half.
Have not tried the software.
The trick of these chu are ultra low distortion so you always discern it added deliberately or not NTO the mix, not the transducer.
NO SNAPS CRACKLES OR POPS out of this dac/amp. The cable feels very good in hand and looks fine, very low microphonics. Just the right length. Draws no attention. Mic is a little low.
Much superior to a dongle for walking with.
Isolation is more than average.

Does this come with a microphone?

Linsoul Audio

Hi there!

Yes — the DSP version of Moondrop CHU II does come with a built-in microphone in the USB-C cable.

If you prefer to use them without the mic, you can always swap to a plain cable, but by default the DSP bundle includes mic + inline controls.

Fit, connections and your order.
