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)

Short version: Absolutely perfect lossless sound on AKGs and Bose over the ear headphones while plugged into iphone 15 pro max and iphone 17 and other apple products. God they sound good when streamed with Apple’s lossless option. Long version: Who needs to know more? Well… we all base our decisions on numerous input. So here goes. There are a number of options with the DAC CX31993 & MAX97220. Many similar in the customer rating. After narrowing down the ratings to over 4, I then looked at how many ratings there were for each adapter and eliminated any of the choices that were under 100 reviews. Then narrowed it to the two with high ratings and over 200 reviews. Reading through each review posted, on both positive and negative. Then chose the JCALLY JM6 Pros. Had never heard of the brand before this. Just wanted to try them out. About the adapter: These make you feel like you are sitting in the studio where the music is being mixed. They sound like the day they were recorded. But, you have to have excellent headphones to take advantage of what it is capable of playing. What that means is, the song sounds as if you were there when it was made. Not a bunch of lost bits that muddy the sound. For example, I have a pair of really cheap $10 Sonys for light work that doesn’t need to be crisp. It also means you need to have a recording that hasn’t been transferred from device to device repeatedly, where bits could be lost or are streaming on a low quality. Be careful what you ask for though, because you learn which songs weren’t mixed well. In one of the Queen songs, “I want it all” I could hear a noise from when the guitar was added in the middle of the song for a solo. It was really harsh. It looks and feels durable. Colors are as represented. Have only tried it on apple products directly into the C connector. Did not use any adapters and used a limited number of headphones, because most of those I have are bluetooth. Functions properly with no need to do anything but plug it in to headphones and the device connector. Just turn the music on and it works fine with no additional work needed. There was plenty of power in the included MAX97220 to use in our studio monitor gold AKGs. In fact, did not have to turn the volume the whole way up to get quality sound. Told my recording musician and hypercritical audiophile spouse about them and what a pleasure it was to listen to assorted music. Thinking spouse would find something negative to say about the JM6 Pro USB C Type-C to 3.5mm Dual DAC CX31993/Max97220 adapter. Instead he was quite pleased with the device and asked for the link. The only negative was that you do not get the 3D spacial auditory experience that some of the bluetooth connections offer. Unfortunately, I do not have any powered spatial sounding headphones that allow you to connect via wire. I use the song “Baba O’ Reilly” by The Who to test that functionality on new headphones. You do get stereo sound without any issues though. That being said, there is some loss on all my bluetooth options (apple airpods 3 and 2, Bose Quiet Comfort in several models), which muddies the sound just a bit. Advantage goes to the adapter though for clean, crisp lossless sound. Will have to check to see if anyone has plug in sound with spatial options. I read some of the reviews that mention a different type of headphone I had not heard of before. Going to research those. The price of $17.99 full price I paid seems cheap when compared to the ridiculous amount of money spent on some of the headphones out there. And they sound better than any bluetooth headphones I have ever heard/purchased from the crispness of the sound. Finally, I do not like sticking earbuds in all the time. They have to be cleaned regularly and do block the ear canal. Which can lead to ear infections when there are trapped little infectious critters. Which means I have to regularly disinfect the earbud where it goes into the ear and that can be tricky business with the air pods. As they are not the least bit waterproof.

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.

The quality of sound compaired to listening over bluetooth on my Sony XM5s is amazing. From my knockoff XSTs to my Truthear X Crinacle Blue2s, this thing sounds amazing. I'm no audiophile. I'm just experimenting to see if i can hear a difference. The JM6 adapter on my Galaxy s23 Ultra really allowed me to see that there is better sound than what bluetooth can offer with LDAC enabled. I have the following BT audio gear: Sony WH-1000XM4, Sony WF-1000XM4, Sony WF-1000XM5, Samsung Galaxy Buds Pro (gen 1). I'm listening to CD quality audio, HiRes digital audio, and supposed HiRes streaming. I was also using the PowerAmp EQ app to find tube the sound. There was no night and day difference between using the adapter with wired IEMs and listening over bluetooth, but there was a difference. Imagine listening from the front row while a band plays live. Then, imagine doing the exact same thing, but there is a thick stage curtain between you and the band. Not enough to fully muffle the sound, but enough to muddy it noticeably. This is the level of audio difference i was hearing. Don't take my word for it. It's cheap and returns are easy. Just give it a try. Also, if you have never heard it before, try listening to some 8D audio. You can just search YouTube for it. It will completely change your understanding on what sound stage is and how capable 2 channel audio can be.

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.

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.

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.

I was reading/watching a lot of reviews of different DACs and decided to purchase this one, and I'm super happy with the purchase. I have been using the DAC for the last 10 days with Beyerdynamic DT 770 Pro (80 ohm), and I want to share my experience. -It definitely has enough power to boost the Beyerdynamic. I'm usually at about 75% volume. -The sound is good to my ears. -The USB C and headphone jack connectors are solid. -It doesn't get warm. -It's small and convenient to walk around with. For warranty/return reasons, I have bought it here on Amazon for 21€, but I saw that on other platforms, one can get it much cheaper.

Non avevo grandi attese, ma questo "mini dac" aiuta tantissimo a migliorare il suono ascoltando da una fonte come un telefono. A parità di volume, il suono é molto più aperto e presente, senza quell'impressione di essere ovattato. Ho notato la differenza usando delle buone cuffie, ma anche con modelli più basici si avverte. Consiglio l'acquisto!

Bought these along with Zero: Blue 2’s - for PC gaming/discord/youtube/music. First time using IEMs and this dac was recommended many times through reddit posts. Works as intended. Delivered quickly to Aus.

L'ho collegato ad un MiniPC con "Linux Mint 22.2" (kernel 6.14.0-36) ed è stato immediatamente riconosciuto come scheda audio esterna con le seguenti caratteristiche: Synaptics CX31993+MAX97220 HiFiAudio, driver: hid-generic,snd-usb-audio,usbhid. Le capacità di conversione da analogico a digitale del "JCALLY JM6 Pro" arrivano fino a 384 kHz/32 bit. Una capacità esuberante rispetto alle normali necessità di ascolto di un brano audio, che per i CD è di 44,1 kHz/16 bit. Io uso OBS Studio per registrare qualiasi cosa arrivi al PC, come per esempio i video di Youtube. Il "JCALLY JM6 Pro" trasforma in analogico i bit che arrivano da Internet ed invia il segnale audio agli altoparlanti. OBS Studio digitalizza a 48 kHz/16 bit il segnale audio in uscita e registra i bit su un file audio/video in formato mkv. Con ffmpeg posso estrarre il solo file audio in formato m4a. Nonostante i due passaggi consecutivi attraverso il "JCALLY JM6 Pro" è incredibile la qualità audio dei file ottenuti. In uscita al "JCALLY JM6 Pro" ho messo le cuffie over ear ad alta risoluzione "Philips Fidelio X2". Miracolo! La spazialità ed il dettaglio dell'audio che sento in cuffia sono supremi.

Really powerful dongle combo dac/amp, especially for the price. No audible distortion at all, can drive almost all IEM's and most headphones. Also has a really nice cable, but it is a bit stiff though. Only unfortunate thing is that it only comes in 2 colors. If you are new to the audiophile world, OR you are looking for a new dongle dac, then I definitely recommend this one.
