On business travel for the first time since January 2020, prior to covid it was a regular occurrence. I always love selecting music on different stages of travel - waiting in the airport, up in the sky, on trains and walking in the city after work... or indeed like right now, in my hotel room.
I brought IE900 with foam tips for isolation in noisy environments on the go and IER-M9 for relaxing in my room. IE900 is an almost daily driver anyway but first proper revisit to IER-M9 in a while - fallen in love all over again, I get completely lost in them and outside of single DDs, the best coherency I've heard in any IEM. When I got Traillii I debated selling some others to include IER-M9, definitely not going anywhere now!
