32Bit USB C DAC AMP Headphone Adapter Portable Amplifier Male to Female 3.5mm Audio Cable Premium Sound Enhancer for Phones iPad Pro MacBook Switch PS5 Black

I usually do not write reviews unless I have a problem with a product. But these guys deserve the credit. Let me start by saying that I am a Audiophile, most of my earphones, amps and dacs run upwards of $1k a piece. So you can trust that I know what I am talking about, when I say this little chinese DAC is a winner for $20!I have plenty of HiRes DAC's that are better than this, sure, but none of them support the microphone on caller headset cables. I needed something inconspicous and portable that would allow me to use my microphone to make a call. This worked flawlessly on my Galaxy Note 10 plus and I was really surprised with the audio quality. For $20, I honestly do not believe you will find a better sounding USB-C DAC. I would say the DAC/Amp is even better than Samsung Galaxy's internal chips. Unfortunately Samsung is ditching the 3.5mm jack from now on, which is a huge mistake IMO, as it puts too much excessive wear on the USB jack for starters. Fortunately for us we atleast have a suitable substitute with this little winner.Not sure it will hold up, but even if it lasts for only a year, it is still a solid option for people who have 3.5mm headsets.I will be honest with this last statement. Wired headphones will always be superior sounding, BT earbuds are a scam, they cost allot more and make allot of sacrifices to run off tiny batteries. All of the best legit Hi-Res earphones are wired, 3.5mm or 2.5mm balanced. This will never change, for the same reason Audiophiles are still scouring the earth for old transistor tubes made in the 1950's. Old crumbly moldy boxed tubes that costed 5cents back in the day are being litterally faught over for hundreds of dollars a tube. The marketing hype fooled the masses into adopting the inferior solid state transistor chips, only the Audiophiles were the wiser. Shaking our heads in shame, as we see a similar mistake being marketed to the masses again in the form of "wireless". When it comes to Audio the old systems and analog technologies are still the best and will remain top dog for the foreseeable future. Just as the old Stradivarius Violin is still undisputedly superior to every synthetic composite or carbon fiber violin produced today. The wired premium earphone market is just now beginning to reach its potential, with AMAZING multi dynamic driver and balanced armature IEM's. There are hybrid disigns with internal crossovers that are being born now, that would blow your friggen mind! New exciting modular cables with well designed braids and alloys that are truly allowing the audiophile to have perfection in sound down to the smallest detail. Streaming services like Tidal that allow you to hear a STUDIO MASTER track of unlimited artists, simply by using a cellphone and typing in the band. There is a whole beautiful new world of sound emerging yet to really become a member, you need one simple thing, a friggin audio jack! You will find none of this in the tinny, single low quality driver, limited bandwidth blue tooth land of wireless earbuds. Wireless is just marketing trash, sure its convienient, but is it really?? How many times have you lost your BT, or forgot to charge it? I honestly dont really see the appeal of an inferior wireless technology, that is as hard on the wallet as it is on the body. Because as a Aircraft Electrician, I can tell you that keeping your brain sandwitched between two wireless transmitters is a VERY BAD idea, but that is a whole nother can of worms entirely.Until Samsung realizes its mistake and gives us back our beloved, future proof audio jack, I will be keeping this little slugger in my pocket. Everyone else can have their crappy wireless buds and brain tumors. Just buy one!

One sentence should tell you all you need to know about this DAC...It is actually capable of driving Sennheiser HD650s to a reasonably high output level. If that doesn't convince you that these are worth the measly price tag, nothing will. I'm serious about that. I own the HD650s and normally use them with my gaming PC and a Schiit stack (Magni + Modi combo). Obviously this little DAC plugged into a cell phone can't reproduce the volume or quality of that signal chain, but you will be shocked (as I was) that they can actually drive a 300 ohm can to a reasonable volume (from a cell phone). I say reasonable because it is by no means loud, but its loud enough and sounds fine if you feel like taking your cans on the road. Personally I don't, I have a set of Sennheiser ear-buds that I use with my cell phone at work and they sound just fine with this DAC. Better than they did with the old USB-C DAC that I had.I've only owned this for a couple weeks now so I can't speak to longevity (and that tends to be an issue with these) so this review may change. But for the money, I wouldn't be upset if they only lasted a year and needed to be replaced.

I have a new phone that doesn't have the 3.5mm jack and needed to purchase a USB-C adapter to plug my microphone into this new phone. After looking at a bunch that claim to be what I needed, none of them worked. This one was at the bottom of my list because of the price. But after the other models that I purchased never working the way they were supposed to, I decided that I'll get this one and return it if it didn't work.When it arrived I was first surprised that it came in an actual box, not just in a small plastic bag. This one actually had a foam lined box that had a cut out just for the adapter. This was looking promising. I took it out of the packaging, plugged it into my phone and microphone and started the video camera app. The app had recognized that I was using a USB microphone and had automatically selected it. Another pleasant surprise. I then hit the record button and started talking into the microphone.When I played back the recording I honestly thought that it wouldn't have recorded anything. But it did! I was happy with the device. I would recommend this USB-C to 3.5mm adapter to anyone who has a phone that doesn't have a 3.5mm socket and needs to plug in a microphone to record audio for video.Why a four star rating then? Well, the wire between the two ends of the device is rather thin. Had it been thicker and felt more robust, it would have been a five star rating. This thin wire doesn't make any difference in the recording quality, that is up to your microphone and the capability of your phone.Here is what I used for my set up:Phone is a Samsung Galaxy Note 10+, microphone is the Rode Video-micro and the video camera app is the full versions of FilmicPRO and Moment apps. I also tried it on the included Samsung video camera app and it worked.I don't know if this will work on other devices. I'm sure there are other reviews out there that can let you know if it works with your device. My experience is only on the Note 10+.Cheers!
