Dudios Zeus Ace – TWS on a budget

Hello everyone!
After some times around on forums, i’ve been contacted by many people asking for TWS earphones advices. As i didn’t have any of em, i got contacted by Carrie on my social page, who offered me a sample of the Dudios Zeus Ace in exchange of a honest review.
Let’s get into the review, cannot wait to tell you how these Dudios Zeus Ace perform!

You can buy the Dudios Zeus Ace by clicking on the link at the end of the review!

Just wanna precise that my impressions are subjective and that listening experience can change depending on source, tips and so on.

Test were made on:
– Galaxy S7 Edge Smartphone
– AGPTEK M30B/Benjie S8 DAP with bluetooth connectivity

Technical specs:
IPX4: water splashing protection avoid IEMs getting damaged from light rain or sweat
Bluetooth 5.0
Maximum working range: 33feet/10m (no obstacles)
Standby time: 120 hours
Talk time: 4 hours
Earbuds charging time: 1.5 hour
Charging case Recharge headphones: 9-10 times (both earbuds)
Each earbud weighs 4.7g


Packaging is nothing special: carton box that hides the product, 3 different pair of tips and a USB cable to charge the Dudios charging case.


My experience with the Dudios Zeus Ace was great: connectivity is super fast with my S7 edge and even with my dad’s Mate20 Pro.
As soon as you disconnect both earbuds at the same time from the charging box, they connect each others and are ready to be connected to the smartphone. I’ve even tried going a bit far from the smartphone while having them in my ears and the declared maximum distance of 10 metres was quite precise. You can even use just one earbud at time without removing both from the charging station and that will result in a MONO sound with a single earbud.


Build quality is good. The earbuds are completely made of plastic with a button that features a led which displays different colors in different situations (battery status, connection status, charging status and so on). The button feels responsive and it’s easy to click, and can be used to play/pause, answer to calls, use the google assistant and more.
Battery stands up for a fair amount of time: my listening session ended up at 3.5 hours with high volume, so the declared playtime is a fairly precise (if you don’t use them at a high volume they will sure reach the 4hours). I have tried carrying them without charging the case for some days and i have reached near 8 charges with just one case complete recharge. A good result considering many times the advertised informations about battery aren’t true.


Comfort in my case is good, i have no problem wearing them, but if you have very small ears i would suggest avoiding these. I’ve tried swapping the tips with other tips i’ve got in my collection but i have to say the stock tips included with the product just feel great on the earbuds. Isolation is really solid and you won’t regret using them in the city. Plus, the IPX4 cert. is a good thing if you plan to carry these out: sweat and soft rain are not a problem anymore. I’ve tried them under soft rain and running: they still work well, confirming IPX4 certification.


Let’s get into it.

Now the critical factor that decides if something has to be tried or not: how do they sound? I mainly listen to EDM subgenres, from Dupstep and Future Bass to some more genres which represent a niche in the music market. I even like listening to vocal tracks (moreover from female singers like Sia) and sometimes Rock tracks. I always search for IEMs that have a little bit of emphasis in the lower region, and can sacrifice mids with some recession if they still sound clear and natural. I love vivid and sparkling highs if they’re not at a headache level. Soundstage has to be at least average with a bit of air.
V-shape signature is my favourite one.

Lows: lows are emphasized with great sub-bass extension and punchy deep bass. This is a common thing in budget earphones or in mass-targeted earphones, which result in a bassy earphone that matches the common “fun” taste. The low-end bleeds a tad in the midrange but not in a bad way.
I’ve noticed the low-end was having some distortion at high volumes in the first days, but this disappeared with some use. I think the driver just needed to settle a bit.

Mids: mids are recessed with some bleed from the bass region which gives a good amount of warmth. Female voices, on the other side, do not sound bad, with good results listening to Sia as well.

Highs: highs are not fatiguing at all. I have to say.. i always prefer much detail in this zone, and the Ace are not the most detailed earphones, but they carry out a good amount of energy that makes me forget i have more expensive pairs in my collection, even considering this is the first TWS i personally own, as the other ones were just borrowed from friends (like the Airpods).

Soundstage is a real surprise, so big! It is very expansive with above average height and width and average depth. Instrument separation is ok but i would avoid putting very complex tracks in these. Imaging is pretty good considering they’re TWS and that in this price range quite everything is just crap in terms of sound.

A little comparison with the Apple Airpods
Why am I making a comparison with the Airpods that cost like 150$?
Then, i wanna be sincere. The Dudios Zeus Ace are really surprising. Connectivity wasn’t so good in other products from chinese companies, and this is a big plus for the Ace.

Did it reach the super connectivity of the Airpods? Nope, they didn’t, but they’re sure at a good 80% of it. Trust me, it’s an awesome result imho.

Functionality? Airpods are a bit more well studied, but that’s ok considering the price.

Comfort? Airpods are always preferred but in my case, Dudios Zeus Ace win hands down: they fit well in my ears and the isolation is crazy compared to the Airpods which gave me just a very little sensation of wearing something in my ears without blocking outside noise if not increasing the volume.

Sound: mates, the Dudios Zeus Ace really show to Airpods what means sounding good.
The low-end is nicely extended in the Ace, making the Airpods a bad copy in terms of sound. Midrange is recessed but sound full with warm male voices and intimate female voices, something Airpods cannot really achieve. Upper-range is warmer in the Ace making these an absolute preference if you’re treble sensitive, while the Airpods have a little artificial boost in the upper end that gives some air without carrying out a real detailed experience.

Stage is much more expansive in the Ace, with better width, height and depth, making them more fun and engaging, something Airpods really cannot give me. Instrument separation is on par, while the Ace win in imaging.

Just saying: the Dudios Zeus Ace just destroys the Airpods in terms of price/quality ratio. They sound more engaging, more fun and have a warmer timbre which gives them another point against their super expensive “competitor” (which isn’t a competitor if we have to be precise, as the price range is totally different).


Dudios really surprised me. When i first got contacted for these i thought about someone who just wanted a good review for a common “bad” product. I had the chance to speak with Carrie that said he would have a sincere review of these even if i had more expensive product and i wanted to give Dudios a chance. Carrie wasn’t wrong: their product is really good and the price is great for what they offer.
If i’ll have the chance to advice a pair of TWS earphones to someone on a budget, the Zeus Ace will be my first choice. Plus, considering they’re somehow under Soundpeats, customer service should be good: practically a must have if you’re searching for TWS and you’re on a budget.

Big thanks to Carrie and Dudios for the review sample! Keep up the good work!

Dudios Zeus Ace




Build Quality


Comfort (subjective)







  • Great sound quality considering the majority of TWS in ear are just garbage
  • Awesome battery life: 3.5 hours average is good considering many competitors just stand up around 1hour
  • Lightweight, well built, responsive buttons
  • Good connectivity: bluetooth 5.0 works almost flawlessly
  • Price: killer value


  • Could be big for people with very small ears
  • Could carry out a bit more details, but i'm still happy
  • High competition in this price bracket: really hard to distinguish this product but i hope my review + other reviews on the web will highlight these TWS
