Good call. Better to get something now that’s proven vs waiting for something that may not be any better. The TN is A-OK in my book, and I’m sure you’ll be pleased as long as you don’t have unrealistic expectations (both with ANC and with the sound). The ANC is miles better than their full size headphone implementation, but it’s no Bose ANC. The sound is better than other Bluetooth IEMs I’ve heard, but it’s no CA Andromeda. They’ll be more than good enough for the gym IMO.
