Very good transparency mode with very little latency. Usually the noise cancellation doesn’t allow you to have a conversation with someone but if you just double tap the left earpiece it will amplify surrounding sounds allowing you to hear what’s going around you. You can use this even while listening to music. The headphones a very tightly fixed within your ear as well. I have played basketball with them for 3 hours and I didn’t even need to fix them in place once.
