Phonak and ReSound are both leading brands with strong speech-in-noise performance and phone connectivity. Phonak (Sonova) offers the widest range including premium flagship models. ReSound (GN) has a broad range from budget Key to advanced Vivia. The better one is the one that suits your loss and lifestyle in a trial.

The direct answer

Neither Phonak nor ReSound is universally better. Both make excellent, well-supported hearing aids. Phonak, from Sonova, has the broadest range and a strong reputation for speech in noise. ReSound, from GN, has a wide spread from budget to advanced lines and a long record in phone connectivity. The right choice depends on your audiogram, ear shape, lifestyle, phone and budget, and is best decided in a side-by-side trial.
