Really impressed!!!! (Lightning connector version)
I bought the lightning connector version to use it with my iPhone and my Sennheiser HD-58x.
To tell you the truth I wasn't expecting much and had this been more expensive I probably wouldn't buy it. Boy was I wrong...
First of all the built quality is excellent, the connectors feel solid and the little cables attached to them don't seem flimsy. Playing Tidal masters from my iPhone through this cable-dac to my Senns 58x brings a solidity to the sound that I hadn't heard before.
It definitely sounds to me more warm than the stock iPhone dongle. The mid-bass and lower frequencies have way more punch, texture and definition. The good thing is that the midrange that the Sennheisers are known for, is still there unadulterated. The higher frequencies are a little bit rolled off (at least this is what it sounds like to me) which in turn makes this little cable-dac sound a little dark but this is actually the sound I prefer in general. I stay away from the analytical presentation whenever I can.
Now I am waiting for another Drop of this cable-dac so I can buy one more to have as a backup.

Improves audio quality!
I'm really impressed with these I'm using my ETY ER4SR for these and it makes them sound even more neutral compared to my standard headphone jack which does get a tad louder but it's also a birighter sounding DAC and puts a but more emphasis on the low end(my phone is the Moto G Stylus)

A step up from Apple dongle
Nice solid build and flexible soft braided cable that feels pleasurable to the touch. Sound quality is a step above the Apple dongles, but the price is too high IMO. The only thing that irks me is the popping and static when removing or inserting headphone jack. This dongle will not replace your more expensive ones, such as my Lotoo PAW S2 which I adore as it makes my 6XX dig deep and sing with authority.

Very impressive USB-C Adapter
Phone: Oneplus 6T
Adapter: USB-c to 3.5 mm
Definitely an interesting adapter for some good quality audio! Very good quality and very well built with the interwoven cables. The adapter really enhanced the audio experience and I would definitely recommend if you're looking for a high quality adapter!

Hayabusa7Glad you mentioned having the 6T, as that's what I'm using. Just might have to check these out.

Pryor0nFireThe 6T has a built in DAC, you just need a passive cable. I'm not sure how it compares to the one in this cable, though. (just noticed this was over a year old, oh well).

No improvement over Apple adaptor
Build quality and look is ok. Sound is arguably slightly clearer than the apple dongle but brings a hardness to treble and generally less refinement. Not worth the money.

Improved sound (Lightning), sketchy build quality
iPhone XS - side-by-side comparison with Apple dongle.
Using Shure SE215 IEMs, expanded bass, mid-highs improved. More clarity (less muddy) and mildly expanded soundstage. Approx 20% improvement over the Apple dongle (subjective).
K7xx had similar performance improvements but noticeably better volume level.
Braided cable looks cool and visually seems like it’s solidly assembled, BUT...
There is a significant lack of retention strength of the headphone cable jack in the 3.5mm female side. Extraction force can’t be more than 1-2 Nm. No noticeable “click” upon insertion. Tried 3 diff cables to compare, all the same. Not sure how long before the jack will start to fall out on its own. Disappointing. Will likely return the product.
The lightning end seems solidly connected to the iPhone, so at least that is ok.

CR31Hopefully I won't have this problem. This is going to be my solution for better tunes in my 09 civic. Via a 3.5 mm aux cable. Thank you for the review.

The description lies! At least for iPhone users.
The description reads:
“With this hardware, MK2 adapters can decode audio up to 32 bits at 384 kHz”
but when I go to the website it says:
“Supports High Res audio transmission- internal Realtek DAC is able to decode files up to 16 Bit/ 48 HZ music”
I confirmed this when I plug it into my iPhone and check my stats on Amazon HD it still says 24/48k. I think this is a huge over site on Drops end and now I’m wondering what other products they let lie on their site.
Build quality is still good but it’s not a significant upgrade over the standard dongle.

If it worked as intended I would replace my current pixel 2 dongle.
Unfortunately I get static when using this DAC with my phone and pc. I cannot recommend this product.
EDIT: I do use this in my car on occasion, it is a great sounding DAC I still don't know why i have static on occasion.

A pricey meh
Honestly the sound quality ain't bad at all, yet the user experience is pretty bad in general staring with the fact that it wont dettect if your headphones/iems/headset... are connected or not wich can seem like a little dettail but for the price could have been included, the building quality is fine I guess, but the little cables and the structure that is not aluminum feels somewhat cheap, cables tend to get messy in the pocket or even when moving it arround a bit, it is still quite resistent as I have some little "oh no my phone is falling" incidents and it holds it pretty nicely. To sum up, it is nice in sound quality and even amps a little bit some iems that may have a "low base volume" but it could have been more for the price both in software/interaction as in build quality since a little plastic arround the cables would have been a big difference.

Don’t waste your time or money (*Lightning Version)
It allows you to connect your wired (3.5mm) headphones to your phone at best and at worst you just wasted over 30 dollars on something that isn’t even heavy enough to be used as a paperweight and it sounds worse than an Apple 3.5mm to Lightning adapter. Sure it gets the job done, in that it will connect wired headphones to your phone (iPhone 15 Max in my case), but honestly I barely noticed any difference when compared to a basic 3.5mm to lightning adapter paired with the DAC inside of my phone when compared to this adapter & its external DAC. if anything I think the existing internal iPhone DAC might sound slightly better. It’s for sure more convenient. So don’t waste your money, if this was more than $30 I might go return it, but to pack it up and ship it back isn’t worth my time and effort with Los Angeles traffic being what it is. So If you’re going to get an external DAC & adapter combo like this one for $30+ you might as well get yourself a better dongle for $20-$30 more as it will provide you with extra power and better sound. This is honestly one of the most disappointing purchases I’ve made to date at drop.com. (I’ve owned many products sold by Drop and a few that were developed in conjunction with Drop; Focal Elex, HD58X, HD6XX, Edition XX, THX 789 Amp, Grace DAC, PC38X, …) Most of these products I have loved, or at least liked/enjoyed, but this thing is going straight into the trash can where it belongs. I haven’t been this disappointed in a drop.com purchase since the HD8XX and its ridiculous sticker “damping” that completely ruined the magical soundstage and treble the HD800S had when paired with a decent tube amp for music or when just gaming in general. I know Drop didn’t design these or collaborate with the company, but surely they must test a product before selling it to their customers. I can’t imagine anyone hearing this and saying “That’s a clear improvement over an iPhone internal DAC. Our customers will love this and gladly pay $35 for it.” If someone said anything even close to that after hearing this DAC / adapter then they should be fired immediately.
I apologize for the long-winded and clearly negative review, but I’m hoping my experience with this product can stop at least 1 person from making the same mistake that I did by wasting hard-earned money on something that is nothing more than electronic waste that will surely end up in a landfill.
P.S.
I’m still a “fan” of Drop.com, but they need to do better in the future if I am going to keep coming back in the future. (Prime example beyond this item is their own FOCAL x DROP ELEX headphones that are currently selling for hundreds less on headphones.com {$699 on Drop.com | $499 on Headphones.com} ) Their prices aren’t even competitive on their own gear anymore?!?? And they don’t bother to price match like other sites.
