SPORT True Wireless

The only common thing between the WF-1000XM5 and the Sennheiser Sport TWS is that both are TWS headphones; the similarities end there. While the XM5 has ANC, this Sennheiser model does not have ANC, and apparently, 'Focus' and 'Aware' states can only be achieved by changing the tips. You should compare XM5 with Momentum TW4. I heard it's noise cancelation is not as good as XM5 but but it would be a fairer comparison in terms of sound isolation

Dude I have waaaay cheaper 6 y.o. bluetooth earbuds with battery life as good as on the first day (Sennheiser CX Sport, Lypertek Z3). The battery degrading this quickly is definetly not just physics (it's chemistry actually). You can make batteries that last longer. That is so weird that people would just accept that they just fail after a while. Also with the rise in populartiy of many IEMs wearing out a cable is also not an issue anymore, since cables are easily removable. Wainting to see that happen on standard cable earbuds though.

Agree on the sound. And performs very well in wet/sweaty conditions. But the battery life is dismal after 2 years, barely lasting an hour. Also, it’s a bigger earbud so it feels bulkier in my ear but has never fallen out. I do love the aware mode that lets you hear sounds in your environment, like traffic or wildlife or passing runners/bikes.

I’ve been using sennheiser sport true wireless for almost two months now and I’ve had no issues with them. I go for a four to five miles run and they stay in my ears. I do cardio and weights in the gym and the stay in my ears. I used to use my AirPods Pro 2 for those activities but now I use the senn sport more often. I have regular size ears and i sweat regular as well. Good luck to you.

I can tell you what not to get. I hate my sennheiser sports true wireless earbuds. They were alright for a while but now the right bud only charges to 20% so it dies on every run lol so frustrating.
