Maximum Noise Isolation, Comfortable / Secure-Fit
The Model X is a byproduct of countless designs to ensure universal fitment for various ear shapes and sizes.  The nozzle length is purposely elongated to be inserted deep into the ear canal and the round and compact earbud body allows it to fit ergonomically in the concha. This allows secure yet comfortable universal fitment without needing additional ear hooks or guide.  Deep insertion of the nozzle results in maximum noise isolation up to 23dB.

Advanced Sound Model X User Guide


It took a few days before I could reliably get the right earphone to pair reliably when removing it from the case. Things seem to have stabilized and now pairing is quick. The bluetooth range is good also, I can walk all over my apartment and not loose connectivity. I'm not an audiophile, but the sound quality is fine for podcasts and music. Occasionally the left and right get out of sync listening to a podcast, but only momentarily.

My only complaint is the tips. I normally use foam and the included foam tips were all the same size and too small. It would have been nice to get 3 sizes of foam tips, but I see they're not even for sale yet, only a 6 pack of size small is available. The silicone tips aren't great either, but at least 3 sizes were included.


For the past few months, I've been using the Samsung Gear IconX as my "truly wireless" earbuds/workout earbuds. Instantly after putting these on, the sound quality is overall fuller with richer bass. That alone made switching over easy.

What's crazy about the quality, is the size it comes in. When I first picked up the Model X, I was shocked at how light they were. I don't even realize I'm wearing them, honest. Their carrying case is small, much more compared to the Samsung's case. Also, the buds sit in my ears securely without any uncomfortable ear hooks like the Samsung buds yet still stay in throughout workouts and even basketball shoot arounds. They allow me to focus on my workouts and music without worrying about them falling out.

The only things I can say I miss from my pair of IconX are the ability to listen to ambient sound and easier pairing. While I love the isolation that comes with Model X, it can be useful in the city to be able to maintain awareness of your surroundings while still wearing both buds. It's also convenient that the Samsung pairs with either left or right bud individually and pairs faster. I like that they pause when you remove them from your ear, but that is something I can live without.

Overall the ADVANCED MODEL X gets a 9/10 from me


after backing these little things on the initial indiegogo campaign a fews months ago the package landed on my desk this morning. As a user of ADV sound product is was sure the build quality and packaging was not going to dispapoint. on opening the package you are greeted with the charging case + the 2 buds.. i must admit my initial expression was "WOW! that's smaller than i expected!!" the charging case is small, how small? a couple of MM fatter than the apple airpods one if you lie them flat on a table a hair taller and a fraction less wide. all in all the initial impression of the case was good. 
so i popped the buds into the case and left them charging for a good two hours till all the lights were off. Pairing was a little problematic first time round with an iphone X running IOS 12.2 but we got there in the end. 
sound quality is good the sound stage is nice and base is present and warm but not overwhelming, mids and highs sound crisp and don't screech so long as you get a good seal from the incredibly TINY tips ... man I’ve never seen them that small ever! 

All in all and at this price point I can safely says that ADV sound have done it again! A decent wireless airbud + case for half the price of many others!

Great job guys!!


These are fantastic. Sound quality comes close to the Sennheiser MTW. Fit is excellent and has a low profile. Touch controls respond better then the Senn’s. The model x performs much above their price. Really nice tw earphones. Great work ADV.
