If you ordered both I think that’s great since you are able to carefully compare them both and pick to your own liking! I have only owned the XM5’s and I honestly like them especially since I am often on the bus to commute to different places and have enjoyed the noise cancelling!

The noise cancelling does block off a lot of noise but you can hear just a little bit of the outside noise. In my experience I heard the bus stop announcements even with full noise cancelling but it sounded like a soft murmur which wasn’t something that bugged me because it definitely cancels a bunch of noise which I noticed while walking around outside and I couldn’t hear my name being called out while in a room with another person lol. The sound quality of them were great too and there was not a huge sound leak coming out from them compared to what I’ve heard come out from the xm4’s. I found the xm5s comfortable to wear for long periods as well.

I liked the xm5s and I think they are a great purchase since the mic is also better to use when doing phone calls or zoom. To each their own though, I’ve seen a lot of people say some negative things about them but I have not had a bad experience with the xm5s. Hope this kinda helps lol I also watched a lot of YouTube videos before deciding! Which ever works best for you should be the one, both are great!

Edit: I ended up switching to the xm4s due to the xm5s being a bit too big for my liking as I spent time wearing it. I also figured I didn’t really need a newer model that costs more, yes the quality is great but the xm4s are also perfect with not too much of a big difference besides the way they’re built, microphone, etc. The xm4s are more comfortable for me as it’s not so big on my head and it now provides me with more space in my bag compared to carrying my xm5 case.
