Why Styletto 5AX
Award-Winning Style Meets Clinical Performance
The Signia Styletto 5AX is the world's first Slim-RIC hearing aid — a device that transforms hearing care into a fashion-forward experience without sacrificing audiological excellence. Powered by the Augmented Xperience (AX) platform, it separates speech from background noise using dual-processing technology, giving you clarity in the conversations that matter most.
Augmented Focus™
Hear Every Word, Even in Noise
Augmented Focus™ uses a unique split-processing architecture to simultaneously enhance speech while suppressing background noise — without blending the two together. The result is a natural, layered soundscape where voices stand out clearly, whether you're at a dinner table, in a busy café, or outdoors on a windy day.
- Dual processor separates speech from background noise
- 8.1 dB SNR improvement in noisy environments
- Preferred by 8 out of 10 users in consumer studies
- Auto-adapts to 7 distinct sound environments
OVP™ 2.0
Your Voice Sounds Natural Again
Own Voice Processing (OVP™ 2.0) is a dedicated processing channel that analyzes and adjusts only your own voice in real time — completely separately from all other sounds. This eliminates the hollow, echoey quality that makes many hearing aid wearers feel unnatural when speaking, resulting in the most natural own-voice experience available.
- Dedicated own-voice processing channel
- 78% increase in conversational participation reported
- Works automatically — no manual adjustments needed
- Clinically validated in peer-reviewed research
Auto EchoShield
Clarity in Reverberant Spaces
Large rooms, tiled halls, houses of worship, and conference spaces create echo and reverberation that can make speech sound muddy and indistinct. Auto EchoShield automatically detects reverberant listening environments and applies targeted processing to reduce the smearing effect of echo — restoring crisp, clear speech intelligibility.
- Automatically activates in reverberant rooms
- Reduces speech smearing from echo and reflection
- No manual program switching required
- Works seamlessly alongside Augmented Focus™
AX Platform
Next-Generation Dual Processing
The Augmented Xperience (AX) platform processes 192,000 data points per second across two independent processing pathways — one for the foreground (speech) and one for the background (environment). These streams are fused at the output stage to create a rich, three-dimensional soundscape that closely resembles natural human hearing.
- 192,000 data points processed per second
- 95% improvement in group speech reception
- 32 channels with 16 gain handles for precise fitting
- Binaural Directionality III for spatial awareness
Direct Bluetooth Streaming
Seamless iOS & Android Connectivity
The Styletto 5AX streams audio directly from your iPhone (MFi) and Android (ASHA) devices — no intermediate streamer required. Take phone calls hands-free, stream music and podcasts, or receive TV audio wirelessly. The 2.4 GHz Bluetooth connection ensures a stable, low-latency audio experience throughout your day.
- Direct MFi streaming for iPhone (hands-free calling)
- Direct ASHA streaming for Android smartphones
- 2.4 GHz Bluetooth — stable, no dropouts
- StreamLine TV & StreamLine Mic accessories available
