JCALLY JM6 Pro USB C Type-C to 3.5mm Dual DAC CX31993 MAX97220 digital audio portable decoding amp Hifi DAC mobile headset adapter for iPhone 15 plus max Galaxy S23 Ultra Android phone(Silver Blue)

I have purchased a number of these DAC/OP Amp Dongles. They are inexpensive, sound excellent, and highly recommended. I use them with a variety of IEM's including Truthear Red Zero 2. Nice amount of power and clarity. Recommend.

I am seriously impressed. I really wanted one with the CS43131 chip which has slightly better specs but more expensive. I wasn't sure whether to get one with the added MAX97220 amplifier with output of 60mW at 32Ω as I heard the white noise might be more pronounced. I am happy to report I heard no objectionable white noise. I would say this has a clean sound. I tested both on my smartphone and computer and I am happy with the sound. My phone does have a 3.5mm jack and I can differentiate the sound profile. This DAC sounds louder thanks to the added amplifier which will benefit higher impedance earbuds. The volume with 3.5mm jack was plenty for me so I had to bring the volume down with this DAC. The cable is very flexible so no problem with stiffness. The usb-c plug was sufficiently snug and will not move around and disconnect easily. The ends are made of aluminum and I did not feel any kind of warming due to the higher power amplifier.

I purchased these to use with my first IEMs. The apple dongle adapter I was using on my Galaxy S25 sounded almost muted at full volume. With this dongle it allowed the full potential of my IEMs.

I was a little skeptical that a USB-C to 3.5mm DAC would make any real difference, but this JCALLY JM6 Pro surprised me. My lossless audio sounds noticeably clearer and fuller using this compared to a basic adapter. I plug my Beats Studio Pro headphones into it, and I can even take phone calls with everything connected, which was a nice bonus. For the price, it honestly feels like a great value. I took a bit of a risk based on a few reviews, and I'm glad I did. I've been using it almost every day for a couple of months, and it still looks and works like new. If you want better sound from your phone without spending a ton, this is absolutely worth it. Of note, there are probably other options for better sound quality, but from what I found, you're getting into studio-quality sound and, frankly, studio prices.

These little dongle DACs are impressive. For critical listening, they're not quite as good as a full-size dongle DAC, such as the Fiio KA17. But, if you're on the go, or your musical tastes don't benefit from critical listening, these are really all you need. They will override your phone's DAC and play through their built-in. In many cases, this will offer you better sound, as phones don't usually offer the best DACs. (Apple being the exception that proves the rule). Volume is still handled by your phone's volume buttons. They're all the same, basically. It's the chipset that matters. Construction as well as performance seem to be fairly equal among all of the models I've tried (I own 3 different makes). These will easily power most IEMs and portable headphones. Be aware, these devices use your phone's battery for power, so expect there to be some drain.

Works as it should, but just too well for my uses. The build quality and sound quality so far have been great. However, when adjusting the volume on my phone to compensate for the boosted loudness, it creates, all other sounds on my phone become excessively loud. So when using it, I have to be very careful of incoming calls or notifications being at unsafe volumes. I suggest only getting an amplified dongle if you have large hard to drive headphones.

I had been using a Helm DAC that seems like it had a weaker amp and I needed to crank the volume on my Galaxy S23 Ultra just to get decent volume on my Sony MDR7506 headphones (63 ohms). The JCALLY JM6 really woke the 7506's up. I only need to have the media volume at 3/4 to 4/5 to get some serious volume into my ear holes. Can't sense any noise when playing off of Tidal - whether it's quiet acoustic music, rock, electronic, etc. Connections were snug and solid and it seems well put together. It does seem like it is a bit more power hungry than the Helm DAC, but it's not bad and totally worth it. As long as it holds up to moderate use, I'll be a happy guy.

Great dac, works as expected, no fuss, no complaints
