The poster doesn’t say what his use/requirement is. So this is difficult.
I don’t have a problem with music, and my aids (Phonak Marvel rechargeable) enhance my listening experience.
Where I have difficulty is TV, especially speech, my aids are connected wirelessly to the TV using the Phonak TV Connector, which can be connected to the TV using an audio cable, or a digital Toslink optical cable, this setup provides excellent sound.
I also have a pair of Senheiser HRD 195 headphones, with the rechargeable base unit. These provide L R balance adjustment, and a basic equaliser, which lifts the higher, above 2kH frequencies, and proves an acceptable listening experience.
On occasion, I use these when watching TV, on my own, with the TV sound off. If theTV sound is on, they suffer from ‘digital’ delay, which manifests itself as an echo, TV loudspeaker sound first, followed by headphone sound a quarter of a second later, and this renders them useless.
