I haven’t worn the Beyond so I can’t comment. The Evoke is their latest technology with added features (SoundSense Learn for one) but I don’t know if the sound has been modified. Widex is known for the performance with music and are very popular with musicians.
I wore the Oticon Alta2 Pros for the last three years and the Evoke are superior to them in every respect but they really stand out with music. the Alta2 was thin, lacked fullness and warmth and was very weak on the bottom end. There is world of difference with the Evoke. Link to my write up below.
