Review: The smooth little brother...... - If you are a fan of Questyle products, then you will love this product. If the m18i and the M15i are the big brother ess based dacs, then this M15C is the little brother that packs a punch. If you just want something very easy yet engaging to listen to, if you are not necessarily an audio file but you want to give your headphones the best shot at presenting music to your ears then get this dongle. The sound coming out of this thing was so smooth and Rich. In many ways it very much reminds me of a cheaper version of the IFI audio go bar. (without the xbass or xspace.) When I tried to compare it to some of the other dongles in my possession to be honest I found myself just listening to music losing Myself in how great it sounded. Is it as analytical as some of the other ones no it's not but it's more engaging and Musical than some of the other dongles.. Ka13, 15 and 17. Ru7, go blue, go bar just to name a few. I found myself getting lost in the music way more than I do some of the other products that I've owned. To me this was very important because for once as opposed to listening to my new details to figure out what separates this from that, I lost myself to just listening to the music. When a product does that to you you know you got a winner. So if you just want something that plays music well that will make your head Bob to the beat of the song or where you can hear the weight of the vocals in an acoustic track then please give this dongle a try. Side note I realize that headphone pairing with some of these dongles people don't always talk about but I'm going to talk about it real quick. If you are an owner of Meze audio products to be truthful this dongle well none of the ones that I mentioned to be honest pair well with their headphones. I have tried them with the 99 Neo and classic and I found that they did not sound great with any of the dongles that I have in my home including the IFI audio Gryphon. Any other headphone I think pairs great . From hifiman to Audeze. I tried the M15 with the he 4xx, he6se v2, Ananda Nano, audeze lcd-gx, and many more including iems, and they all sounded wonderful. So at that price I encourage you guys to give it a try. You won't be disappointed.
Review: The Questyle M15C is a Must-Have... - Having a love for multiple genres of music almost my entire life, I kind of stumbled upon the vast world of In Ear Monitors and their components. Owning three generations of Apple AirPods and recently understanding both the limitations of Bluetooth music fidelity as well as the potential harmful effects of WiFi lead me to the benefits of wired IEMs. Knowing that streaming from my iPhone 17 Pro Max would be essential to my setup, I also understood that a phone is a just phone. A simple Apple dongle can convert the signal but that alone doesn't have adequate power to push fidelity to the next level. This is where the Questyle DAC Amplifier is indispensable. I was immediately blown away by the fullness of sound that this devise provides. Staging and clarity are dramatically exemplified even on 'standard' gain (my preference is generally 'high' gain). Highs, mids and bass levels are spot-on without being too saturated or over-exemplified. Small, compact, portable, and high build-quality are the hallmarks here. Needly to say, I'm very satisfied with the M15C. (My setup: Fosi Audio IM4, okcsc dongle, Tripowin Zoe cable)

### ⭐⭐⭐ Audio quality is good, but has some issues that may be potential dealbreakers for some consumers
*by R***Y on January 21, 2025*

I bought this DAC/AMP to pair with my Xenns Mangird Tea Pros on Cyber Monday. After almost 2 months of using my IEMs with this DAC/AMP, I can provide some of my thoughts and experiences: - The audio quality when it comes to just music is superb, there is nothing that I can notice that is wrong. - Most of the issues I came across arose when I used them with my portable Apple products such as my iPhone 16 Pro and iPad Pro -- I have no experience with issues on MacBooks and Android devices as I do not own any of them. - I have also used this DAC/AMP on my Windows PC and have not had any of the issues that I had with my iPhone and iPad. - Being on voice call with other people while listening to music through this DAC/AMP at the same time was impossible for me on my iPhone and iPad -- the voice call would take priority and the music just turned into crackling noises. - There have been countless incidents where the DAC/AMP completely disconnects audio from my iPhone and/or iPad, causing me to have to unplug and replug it into my device -- I don't know why this happens, but I suspect it to either be something wrong with Apple's new Type-C port, or that the wire that comes with the DAC/AMP has some underlying problems; all-in-all, it's an annoying and frustrating issue, but I can personally live with it for the time being. - I saw another review on this DAC/AMP talking about how there is popping when it comes to this DAC/AMP; I can personally vouch for that, but the thing is I have only come across this issue while using this DAC/AMP to watch YouTube -- a small but noticeable popping noise every time a YouTube video was paused, and it happened every few seconds. I've had my fair share of issues with this DAC/AMP, but ultimately I think it's an okay DAC/AMP for the price.
