They are still very good headphones but I just want them to connect. ### 1/5 — Add support to MW65! *2024-01-21, version 2.0.6* Please add support to MW65! ### 1/5 — Will not connect to MH40 Wireless *2023-12-17, version 2.0.6* Not sure what the issue is here. Headphones paired to my iPhone fine, and the app cannot discover them. Very disappointing ### 1/5 — Expensive garbage *2023-12-07, version 2.0.6* The MW08 earbuds lasted all of a year before the ANC just started loudly hissing. The wireless charger stopped wireless charging after only a few months so this company is getting better at making garbage. The app is basically a useless landing page that tells you it’s connected and allows you to change from ANC off to ear shattering hiss, their version of ANC. For the several months it worked correctly the sound was great but not significantly better than a Sony or Bose. If you want a nice looking product that doesn’t work by all means spend the $400. ### 1/5 — Cannot connect to mw08 *2023-11-29, version 2.0.6* The app could see the earbud, but could not connect to it. Indeed it had never connected to it since the bud was bought new several months ago. ### 1/5 — Blank screen *2023-11-21, version 2.0.5* Even after reading all the negative review, I installed the app to regulate the overkill base of the MD08. The app freezes upon install ### 1/5 — Why No MW07 Plus Support? *2023-11-07, version 2.0.5* Not sure why the app doesn’t support these earbuds. Wanna fill us in? ### 1/5 — Will not connect with MH40 wireless headphones *2023-11-01, version 2.0.5* Simply does not work. ### 1/5 — Doesn’t even connect to the MW50 *2023-09-15, version 2.0.5* $600 headphones, no app support. No ability to customize the sound. Would not buy from this company ever again. ### 1/5 — What happened *2023-09-15, version 2.0.5* The connect app no longer connects to my MW08S I keep hitting confirm and the app just hangs. I’ve deleted and reinstalled a few times ### 1/5 — Won’t even connect to my headphones *2023-08-05, version 2.0.5* I have the MH40 headset that’s paired with my phone but never can be found or connect to this app. If there are firmware updates how am i to get them? ### 1/5 — Will not recognize connected headset *2023-05-20, version 2.0.4* MH40 - Literally connected and listening to Spotify right now. App cannot detect it. Tried all the basic troubleshooting, even reset headphones to factory settings. The app even asks what kind of headset I have, and has instructions for connecting the MH40. Absolutely useless app ### 1/5 — Can’t even connect to supporter headphones *2023-04-03, version 2.0.4* I have the MH40 wireless headphones. They connect to my iPhone 14 Pro just fine via Bluetooth and the headphones themselves sound great. But this app is not a good look for M&D. Following the directions in the app, the app cannot find the MH40’s even though they are connected to the phone. ### 1/5 — Is this app working ? *2023-03-11, version 2.0.2* My mw07 plus are plugged via the Bluetooth of my iPhone 13 Pro and they work perfectly. However the Master and Dynamic app does not detect them at all ....very poor tooling ... ### 1/5 — App won’t recognize earbuds CURRENTLY PLAYING MUSIC *2023-02-24, version 1.0.14* Awful app, horrible connectivity, not even worth the functionality that it barely adds. ### 1/5 — Won’t connect *2023-01-27, version 1.0.14* The app recognized my new MW08 but won’t connect “connection timeout.” I did everything support asked and nothing. I replaced them for a new pair and same issue. New iPhone with latest firmware and iOS. Really frustrating for earbuds over $300. I’m also experiencing weird batter issues where it shows yellow without hardly any use and red after just medium use (far less than red is meant to indicate). I haven’t had either pair long enough to know how much actual charge they’re giving but the indicator suggest I always need to charge them which is annoying. ### 1/5 — Sooo incredibly bad *2023-01-10, version 1.0.14* Like, impossibility bad. App works like it was designed by middle schoolers for a project. A public middle school in the inner city. ## Most critical reviews (10 lowest-rated) ### 1/5 — App just doesn’t work *2025-09-25, version 2.0.9* Looks cool, doesn’t work. Can’t change any settings for my mw09s, says it’s connected, just won’t allow me to change any settings. It worked for the first day, now it just doesn’t. People pay a premium for your products but you can’t even make a reliable app? Terrible. Can’t even switch ANC on and off, a heavily advertised feature is now unavailable to me. 350 dollar ear buds, ridiculous ### 1/5 — Never connects *2025-02-01, version 2.0.9* MD 65 will never connect to this all. No idea what the battery level is at etc. ### 1/5 — App Doesn’t Work *2024-12-13, version 2.0.7* $699 headphones and I cannot connect to this app to save my life. Ive done all the trouble shooting and nothing. I updated firmware thru the Neurable App and still can’t connect. I am able to connect to devices but not the app. What the heck Master & Dynamics. ### 1/5 — The app is generic. *2024-11-04, version 2.0.7* The app’s offerings do not match the price point of the product. Awful. ### 1/5 — Why? *2024-09-25, version 2.0.7* So I downloaded this to update the firmware on my m&d headphones and it couldn’t detect the headphones and it’s so infuriating because the headphones are good quality but the app is not ### 1/5 — No Bang For Your Buck *2024-08-24, version 2.0.7* This app is way too basic. $400 should be elite software. No EQ controls. ### 1/5 — Boo *2024-06-05, version 2.0.7* Still waiting for MW 65 compatibility 2 + years later 🙄 ### 1/5 — Dot make this mistake too!!!!!! *2024-05-15* I was thinking I was the only one but I read the reviews and that happen to another person, I buy a Mg20 bape the never work well I normally if that happen with another companies they replace your headset with master and dynamic you lost your money. They don’t help me with the headset and I lost my money I don’t recommend buy products of this company save your money and look another options ### 1/5 — heinously bad *2024-05-15, version 2.0.7* god there’s not even anywhere to start this app is just pure garbage. 4 year olds could develop something better. connection issues all the time with my MWO8s, transparency and cancellation barely work half of the time, and on top of that the headphones only connect when they want to. terrible app, overpriced terrible product, and just an overall horrendous experience wirh Master & Dynamic. expected so much better from a company such as them. ### 1/5 — APP is Useless MD08 *2024-02-12, version 2.0.7* Had the headphones for a year or so and can never connect to the app. Why bother. Seems to be a problem for over 2 years and still can’t fix. See the same thing in every response. Please reach out. How about fix your app. ## Most praised reviews (10 highest-rated) ### 5/5 — Great app *2025-01-30, version 2.0.9* The app works flawlessly with my MW09s. The Bluetooth management menu makes it super easy to connect to other devices, and I love the custom EQ! ### 5/5 — Blown away *2023-11-19, version 2.0.5* I just got this from the Mercedes f1 team and I thought this would be a horrible par of headphones but it was surprisingly good. ### 5/5 — Great since updates. *2023-03-02, version 2.0.0* Since updating, I have had a great experience. Good job M&D team! ### 5/5 — Great at getting the job done *2021-12-09, version 1.0.10* I saw reviews that the app couldn’t connect to headphones or that there was no EQ but when I opened it up the app connected to my headphones right away without me having to find them. The EQ also works great and it’s really nice to have that customization option. It’s also good to have this app for any firmware updates. ### 5/5 — Simple yet Essential *2021-12-08, version 1.0.10* Great app for essential software updates, Bluetooth connection, etc. No complaints! ### 5/5 — MW08 *2021-06-03, version 1.0.5* If you love a true wireless long lasting battery, high end theater quality sound. Well my friends you found the headphones for the job. Not to mention the app has some very cool functionality for custom setups. Sexy app! Thank you M&D for making music that much better! ### 5/5 — Great app *2021-05-26, version 1.0.5* Really useful companion to the headphones, which I love! ### 5/5 — Simple connection *2021-05-26, version 1.0.5* Despite some of the other reviews I had no trouble setting things up, was a simple process and haven’t had any trouble since. ### 5/5 — Seamless & Simple *2021-05-26, version 1.0.5* Works like a dream ### 5/5 — Brilliant *2021-05-26, version 1.0.5* So good to see an audio brand spend as much time and effort on their app as they do their products - easy to use and looks beautiful. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
