Reviews NICEHCK | NICEHCK NK1 MAX Adapter Cable CX31993 Decoding Chip MAX97220 OP-AMP HiFi Portable Type-C 3.5mm DAC Amplifier Silver-Plated Wire – Real User Experiences

I previously had a JA11 DAC that didn't work well, but I decided to buy this one as an 'upgrade.' The build feels solid and high quality, and it looks even better in person. I've had no issues with noise or sound quality at lower volumes. It works great with my Android 15 phone and Debian laptop, running perfectly at its specs and staying cool. The USB-C connector feels strong, and it comes with a nice plastic cover for the USB-C plug and a converter that matches the overall design. On my laptop, I drive my Crinicle Daybreak IEMS, which have an impedance of 20Ω and a sensitivity of 105dB/mW. I usually set the volume to about 10%, and that's plenty! I appreciate the added AMP chip, and there's no concern about it being too powerful. Thanks to the seller!

Thanks for the quick delivery! The sound quality is really clear. I'm considering getting another one, but I'll see how it holds up over time.

The sound is great! I haven't received the new earphones yet, so I just tried connecting with Apple EarPods, and I think I can notice a difference, but I’m not sure. I'm excited to try them out once the Doonu Titan X arrives!

The cable arrived earlier than expected. The output power is quite high, and it significantly boosts the volume of my music when played through this cable. I’m not entirely sure what it can drive, but personally, I never use more than 30% volume on my vk4. In my opinion, the sound quality is good. However, I’m not sure if the vk4 is particularly sensitive, because I can hear a faint static noise when pausing a track—this lasts for a few seconds before the music goes completely silent. This might happen when the phone stops sending power through the cable. I’ve tested it with three different phones: a Samsung Note 10+, a Poco F5, and a Samsung A25, so I don’t think it’s a device issue. Overall, this is an excellent product with impressive build quality. I’d definitely recommend this cable and would buy it again if needed. Thanks to the seller for the great product!

I’ve tried many adapters from various brands, both cheap and expensive—including the original Apple one. I’m using an iPhone 17 Pro Max, and the issue is that when I use an adapter, I don’t get HD quality audio input from the microphone. If I want to sing karaoke on certain apps or record high-quality audio, this is quite surprising—because this adapter works better than any other adapter I’ve tried; in fact, the sound is even much clearer. This adapter is truly a gem! Thanks to the seller! I’ve tested it on my iPhone 17 Pro Max, and it works perfectly without any glitches!

Super fast delivery, amazing sound quality, and Apple Music recognizes it, letting you enjoy music at 24 bit and 192kHz. It feels really premium to the touch and is made with great materials.

Previously, I had a faulty JA11 DAC, likely due to a quality-control issue. Eventually, I bought this one as an 'upgrade,' even though it was about 10% cheaper. The design is solid and of high quality; it looks even better in person. I haven’t experienced any background noise or sound distortion at low volumes. It works perfectly on my Android 15 phone and on my Debian laptop. It performs exactly as specified, and it feels completely cool to the touch. The USB-C connector feels very sturdy. It comes with a plastic cap for the USB-C plug and a USB-C-to-USB-A adapter that complements the rest of the product nicely. On my laptop, I’m using Crinicle Daybreak IEMS headphones with an impedance of 20Ω at 1kHz and a sensitivity of 105dB/mW at 1kHz. I don’t need to raise the system volume above 25%, and I usually keep it around 10%. I think having a proper AMP chip is really great—and if you’re worried about it delivering too much power, I can assure you that’s not a problem at all. Thanks to the seller!

I've tried a bunch of different adapters, both cheap and pricey, including the original Apple one.

This speaker is very beautiful and matches my Xiaomi Redmi 13 phone perfectly. The sound amplification is great— I only need to set the volume to around 70% to hear clearly enough. Thank you to the seller!

I received it in five days. It was packed with other items but was in perfect shape. I can't wait to hear how it sounds!

It arrived relatively quickly. I really liked the aesthetic, which is why I bought it. This dongle has enough power for basically any IEM and a good portion of headphones. It feels well-built, and while the cable is just okay, it gave me enough confidence. It's a bit large to carry in my pocket and can sway a bit when plugged into my headphones while I'm out, but that's fine. It seems neutral enough that I don't mind the sound signature.

I just connected it without much thought and used it, but after purchasing and hooking it up, the noise disappeared, and the bass became richer. Not sure if it’s because of the device or the connection, but it’s a good surprise!

I bought three prx 용세 베놈 nki max to try out, and I’m not sure if they’re better than my Buzz 3 Pro... But when I use them, the sound definitely gets louder!

I bought it because it looked cute. It seemed a bit tricky to get the sound out of it, but I'm excited to keep trying until I get the hang of it!

Great quality product. It works perfectly with my laptop, and the audio sounds clear without any static. The cable feels nice to the touch and is strong and durable.

Great product! However, with Android devices, these dongles with extra opamps can be pretty loud for IEMs since some Android smartphones have limited volume control, making it hard to adjust the sound in small steps. The lowest volume can be too loud. This limits their use with more affordable Android smartphones that lack fine volume control. I’m thinking about switching to an iPhone for better audio control while listening.

Big thanks to your team for the quick service and awesome product. Absolutely love the mint green shade! Super happy, cheers from Bea in Australia.

Works really well. Boosts volume and sound quality. It's a bit heavy on the bass, which is nice to know.

Works great with my mini PC and smartphone, definitely recommend it for 3.5mm jack HiFi earphones, the DAC chip is fantastic!

This product really impressed me. I have a 5th series sound card from the Canadians (A5), and I think this dongle sounds even more interesting.

This product offers great value for money. It's not perfect, but it's still an amazing price. I currently have the Shanling UA3, Simgot DEW4X, Tenchijin Space, and KiwiEars Allegro Mini, and I feel satisfied with my purchase. I bought it for under 10,000 won and was pleasantly surprised by the neutral sound quality, which is quite decent. It’s definitely clearer than the Simgot DEW4X and has better output than the Shanling, resembling the Tenchijin Space closely, while being almost identical to the KiwiEars Allegro Mini. The sound is well-balanced, not too bland, and has a slight V-shape to it. As a portable option, its value is impressive. While it may feel slightly less than the mentioned portables, the quality compensates for it. It's certainly good enough to pair with earphones below 100,000 won, and for those above that price, you might want to explore other options. Using it with models like the KiwiEars Quintet, Tenchijin Origin, and Simgot Supermix4 gives a slightly less satisfying experience, but it's still perfectly fine with FiiO's bass-heavy models, KiwiEars Melody, Dolce, and Simgot EW100 and 200. Overall, it's an excellent choice for casual use or as an entry-level option since it's so budget-friendly.

The sound quality was just what I expected. There was an issue with the product, but it got sorted out. Totally recommend it!

The sound quality and product quality are really great. I'm super satisfied as it works perfectly with my Xiaomi phone.

The sound is great! I haven't received the new earphones yet, so I just tried connecting with Apple EarPods, and I think I can notice a difference, but I’m not sure. I'm excited to try them out once the Doonu Titan X arrives!

The product looks great and is just as described. When I connected it, the sound quality was good, and it definitely serves its purpose. I would recommend it.

The output is really great. It's not just about the volume, but the HE400SE headphones can deliver a strong sound even at lower levels. The design is decent, and the build quality looks sturdy. I can easily spot the two chips, which gives me confidence in them.

The kz saga combo is pretty nice. There's some fun in setting up a mix with the budget vocal tracks.

The best thing I bought! From the material to the performance, anyone with a 3.5 headset or headphones must have this; it really improves your experience. I've used it with my headset and my IEM.

The KZ ZST-X earphones do have a little bit of white noise when the music stops, but it’s not a big deal. With the KZ EDX Pro X, there's no noise at all. The sound quality is way better than just plugging into a smartphone. I'm happy with them!

Surprisingly great sound quality! The durability is solid too. It doesn't lack bass, and it doesn't sound muddy. It has a strong sound with a wide staging feel. Even cheaper earbuds like the zsn pro2 deliver impressive performance.

Super quick service! Only took 6 days from when I ordered. Wow! A+ for this one. I wish all experiences were this easy!

It's got a nice edge without going overboard, and it really bounces back! I definitely recommend it. It does its job well!

It looks great and I've been using it with my Xperia 5 IV. Thanks to the amp chip, the sound pressure has increased a bit, and the maximum volume is much better, resulting in a more relaxed sound. It's really good and provides a nice sense of security as an external DAC.

great DAC, really improved the audio quality with flac music, and it sounds awesome with the kz zs12 pro 2.

excellent build quality, the sound is flawless, a pronounced V shape, mid frequencies drop a bit depending on the headphones, more than enough power and volume, great product with a USB C to USB A adapter included

awesome dac, great sound and build, really clean background, no hissing even with sensitive iems, I totally recommend this one.

You can really get the best results for this price. I've tried another product before, but the 97220 amplifier definitely improves the output.

Works great! No noticeable color issues or distortion. My letshuoer s12 pro sounds twice as loud now. It also looks really cool!

This product has incredible sound quality! Even at the highest pitch, it doesn't hurt my ears. When connected to any device, the sound transforms into an exceptionally high-quality experience. The technology is amazing; it truly feels like royalty in sound. I was pleasantly surprised while connecting it to my new phone. The audio effects change to high tones, creating a powerful emotional impact throughout my body. It's an incredible product that feels like a dream to own. The world is truly amazing, and we are all connected to this beautiful earth!

This item has great sound quality and is an amazing deal. If you're unsure, go ahead and buy it! Why not hit that buy button? I highly recommend it.

This is always a cost-effective option, and this time it's a solid all-in-one piece that's durable enough for regular use.

This device REALLY enhances the sound a ton! It's amazing, I didn't even think it would be this awesome, now I can't connect my headphones without it! The sound is louder and better quality than directly from my PC or phone.

This DAC really enhances high-end frequencies and brings a nice brightness to the mids. The bass is solid too, doing a great job with the lower end. Plus, it looks great and the USB adapter that comes with it is a nice touch.
