Hi-Res Lossless Music CX Pro USB C to 3.5 mm Audio Adapter HiFi 32bit 384KHz CX31993 Dongle Headphone Amp USB C DAC Compatible with iPhone 15 Pro Max Plus, Galaxy S23 Ultra, Pixel 7 iPad Air Mini

I was having issues with my new phone not having a 3.5mm jack. Most usb-3.5 connectors gave poor sound quality. This one solved the problem

stops all noise and perfect audio quality

Well made great price.

This is one of 6 CX31993 dongles I've purchased. A couple of those were also CX31993/MAX97220 DAC/dongles. It's also the first one I bought and I fell in love with it. That started the hunt for the best CX31993 dongle.The quality appears top-notch. No flaws spotted on the connector housings, jacks or gold-plated connectors. The twisted wire cable looks nice, seems strong and is nice and flexible.The sound on it is amazing. The soundstage is wide for sure, but it's also deep, and picking out individual instruments, voices, percussion and details are easy. It also has a great sense of "air" throughout; the sound is never congested.I don't know what's more amazing, the fact that this great sound comes from such a small package, or that this great sound comes at a cost less than a meal for two at a fast-food restaurant!Of all the dongles I own, and the chips that power them, the CX31993 is my favorite so far (for sound qualities mentioned above). This cable's implementation of the chip is as good as any, and actually sounds better then any of the other brands I've tried. What's the reason? I dint know - cabling? Materials used? Whatever it is, it works, and at this price, it's a no-brainer. Get it!NOTE: The manufacturer has a newer model of this DAC/dongle listed, with gray connectors, sturdier looking cable and, at this time, a couple of bucks cheaper, but to me it does not sound as good as the one in this review.

Lasted a little under a year, but was solid while it was operating.

I reviewed this DAC by listening tests, inspecting the USB traffic, and profiling with an oscilloscope. Yep, it does receive 384kHz at 32bits, although you may be hard-pressed to find audio recorded at that quality.The signal appears quite clean when viewed on the oscilloscope-the filtering is good, notably better than the same from my T480. The Thinkpad's output is my personal baseline for consumer audio, and this manages to beat it, so it earns the check in my book.The sound feels bright but not aggressive, has a and the adapter can throw a LOT of bass before starting to feel muddy. It has a slight V-shaped curve, (1.2dB Stdev) which means the listening experience is pleasant, but it doesn't alter the sound much.The adapter comes in a metal tin surrounded by cheapo foam. I can't complain, it got here in one piece. I'm happy that it's not that terrible stamped plastic that hurts your hands almost as much as the environment.The housing feels nice (it is real metal) although the cable feels floppy and unprotected. I added some heat-shrink tubing to hopefully serve as stress relief, but if it does break before I lose it, I don't think I'll be particularly upset. The value is good, it's definitely worth the $12 that I paid for it.

TLDR; no matter how good this sounds, doesn't justify the inadequate build qualityI'm really disappointed to have to give this a poor review as I was really enjoying using this with my Koss KSC75's connected to my phone for the few weeks before it stopped working. Based on the audio quality, this could have been a five-star review however the braided wires are too brittle and broke in less than a month. Despite doing my best to be careful with it, storingnit in a protective case when not in use, the wiring is not rugged enough for day-to-day use while on the go. The wiring isn't properly reinforced and supported where it enters either connector, so its regularly stressed at a sharp angle under its own weight leading to failure.For the price though, might still be worth plugging into a desktop PC as a cheap, higher bitrate, alternative to the onboard soundcard. Added a lot of detail and texture to game audio.The male-USB-C and female-3.5mm connectors themselves seem just fine. I would happily update my review and purchase another if they sold this same DAC chip and connectors with wiring that was up to the task.

I bought this adapter so I could listen to audiobooks on my Pixel 7, which lacks a stereo jack. For the first couple of weeks this adapter worked great. The sound quality was good and it worked with my phone and earbuds. Then one of the stereo channels started dropping out unless I wiggled the adapter just so. After a week the other channel started dropping out as well, rendering the adapter useless.I got it replaced through the seller's support which, credit where it's due, was fast and professional, not even requiring me to ship back the damaged part. The replacement worked fine for a couple of weeks, confirming that this was not an issue with my phone or my earbuds, but then entered the same failure pattern as the original adapter: one channel started dropping out unless the adapter was wiggled, and then the other as well. At that point I gave up on this model of adapter and ordered one from a different manufacturer.
