ReSound Key 488 HP BTE
The ReSound Key 488 HP BTE is the top tier of ReSound's Key range. It pairs high-power behind-the-ear amplification with Bluetooth streaming, a combination that is usually much more expensive: it connects directly to iPhone and to Android phones supporting ASHA for calls, music and video. It runs on a size 13 battery and adds noise features aimed at speech clarity, without moving you up to a flagship platform.
What the Key 488 is
A plain look at what this model actually gives you, based only on its own spec sheet.
- Style
High-power behind-the-ear
A high-power BTE that drives real amplification for stronger hearing loss, in a case that sits behind the ear.
- Battery
Size 13 battery
Runs on the longer-lasting size 13 disposable cell.
- Streaming
Direct iPhone and Android streaming
Made for iPhone (MFi) plus Android (ASHA), so calls, music and video play straight into the aids.
- Noise
Impulse Noise Reduction
Clips sudden sharp sounds such as cutlery and doors, so they are less jarring.
- Music
Dedicated Music Mode
A listening mode tuned for music rather than speech.
- Spatial
Natural Directionality II
Helps you keep a sense of where sound is coming from while focusing on speech in front of you.
Who it suits (and who should look elsewhere)
An honest fit check, so the money goes to the right device.
- Good fit
Stronger loss plus connectivity
Best for a severe loss when you still want phone streaming, without paying flagship prices.
- Good fit
You want power and clarity in noise
The high-power BTE plus Impulse Noise Reduction suits people who need volume and cleaner speech in noisier places.
- Good fit
You listen to music
The dedicated Music Mode is a genuine plus if music matters to you.
- Look elsewhere
Mild loss, want the smallest aid
If your loss is mild and discretion matters, a RIE like the Key 362 or a custom CIC like the Nexia 4 will suit you better.
- Look elsewhere
You want the best speech-in-noise on offer
For the hardest restaurant and group situations, the flagship Vivia 9 or the Auracast-capable Nexia 761 go further.
- Reminder
It manages, not cures
The Key 488 manages your hearing loss and improves clarity. It does not cure the loss itself.

Key 362 RIE
The value streaming pick, in a lighter RIE shape for mild to moderate loss. Less power than the 488, but streams from iPhone and Android too.

Nexia 761 RIE
A much more advanced RIE with Bluetooth LE Audio and Auracast broadcast. Worth the jump if you spend time in cinemas, airports or auditoriums.
