How important is talking on a mobile phone, listening to music on your phone, watching TV, etc? I’ve tested both and Signia’s Bluetooth accessories for connecting to your phone, computer, TV are not the best. This may be important if you want to record or listen to music via your hearing aids.
With Phonak, you also have to make sure the audiologist sets up a music program with Soundrecover and any compression or noise reduction turned off to give you a clean sound. You may also want the audiologist to boost the bass frequencies to give you a fuller sound for music. Many of the default settings have been optimized for speech clarity vs music.
I prefer Phonak but you need to test both. Don’t be afraid to try other brands too.
