I bought a pair of Master & Dynamic MW07 wireless earbuds, I totally love every aspect of them. However, I have connection issues with my iPhone 8+. When listening to music or watching video (YouTube Music/YT), the music/video just stops playing randomly. Sometimes 5-6 times in one song! I've even experienced that issue on a phone call once or twice. If I forget the device from the bluetooth list, and then re-pair it, it works fine for a while. Have anyone experienced something like this?
I've had no issues whatsoever with the MW07s using my MacBook Pro or windows gaming laptop. I feel this is some issue using them with the iPhone 8+ only...

Did you get the Plus or the older MW07? I just bought the plus and it's seamless with my XS MAX. I was concerned about the lack of AAC but there must be some kind of digital upscaling as an A/B test with the AirPods pro still revealed the MW07+ as the clear winner in sound quality, although slightly below in ANC.

Got the MW07 without the plus.
Is the bluetooth chip in iPhone 8 weaker in any means compared to newer iPhones or my 2019 MacBook Pro?
Just received a call today at the office and thought I should try out the MW07, 5 seconds and it started to disconnect/reconnect all the time (a couple of inches from my phone).
Just after, I listen to music from my MBP for 2 hours without issues. Really annoying. Even tried my girlfriends wireless headphones yesterday and it started to behave the same...
Just get the feeling that the MW07 is not the issue here. I could even walk past the connection range when using my MBP, then go back again and everything worked flawless.

About the sound quality, clearly much richer sound then the AirPods Pro. But that doesn’t help much when I can’t use my phone with them.

Two possible concerns, first is that MW07 old version only supports Bluetooth 4.2, not 5, which is supposed to be more stable. Apparently, iPhone 8 plus specs list support for Bluetooth 5. I did see some reviews of the original MW07 that complained of stutters.

Next thing to try before giving up, make sure you don't have other Bluetooth devices connected to your iPhone. I have 3 wireless headphones I use with my iPhone and I've found the connections can get unstable if I don't manually "disconnect" the devices I'm not using. By this, I mean going into the iPhone settings and selecting "disconnect" (don't need to unpair them). I'll also turn off my other Bluetooth headphones (except my smartwatch). Maybe that will help.

So you mean that Bluetooth 4.2 isn’t really enough to use as phone headset? In that case, I’m super bummed. I bought the non-plus because I didn’t feel that I needed ANC, and the fact that they where $160.

Still, the iPhone must have a much worse Bluetooth chip then my MBP. Otherwise they should have worked as good as with the computer?

I guess it would be good to try use them with a other/newer iPhone.

If you don't need ANC, go for the MW07 GO -- it's another new product for only $199 and here in the states currently on sale for $179. They have the same SQ, BT 5.0 but no noise cancellation and the mic is worse (if that matters). However, they're lighter and were on my short list. If I didn't want the ANC, I would have gone for them.

From what I understand, the older model just suffered from these issues and with iPhone it's only SBC anyway so not the best codec.

Oh OK. Thanks for the info, I’ll check with B&H if I can return them then.

UPDATE.

I actually resolved most of the problem today (I think).
I seems like my MacBook Pro have interfered with the connection even when in sleep in my bag.
I had the described problem as usual today on the subway omw to work, figured it couldn't hurt to try disable the bluetooth on my MBP (which then was in my suit case). Guess what, it then worked seamless all the way to work. I seems like I very much need to "forget" the headphones on my MBP after every use to have it work with my iPhone. This is kind of annoying, but it is OK. I rarely use them with my MBP anyway.

However, still have issues at crowded places with a large amount of active bluetooth devices, for example at the gym. At least now I can use my headphones when I commute.
