What Is the Signia Pure Charge&Go IX?
The Signia Pure Charge&Go IX (Integrated Xperience) is Signia's flagship RIC hearing aid, first launched in October 2023, and it remains the brand's most advanced platform going into 2026. Its standout strength is handling group conversations with multiple speakers.
Signia's RealTime Conversation Enhancement technology uses five focus streams to track multiple moving talkers at once — think a family dinner table or a busy office meeting where several people are speaking at the same time. The new IX chip also delivers a better signal-to-noise ratio than previous generations, resulting in clearer sound in noisy and outdoor environments.
Key Features of the Signia Pure Charge&Go IX
- 48 processing channels for precise, personalized sound tuning
- Own Voice Processing 2.0, so your own voice sounds natural
- Up to 39 hours of battery life, including 5 hours of continuous Bluetooth streaming
- Universal Bluetooth connectivity — iPhone, Android, LE Audio, and now Bluetooth Classic on the newer BCT IX model
- Signia Assistant — an AI-based helper offering 24/7 sound customization and troubleshooting
- CROS and telecoil options available, making it suitable for single-sided hearing loss too
- A portable charging case that provides 3 additional full charges

What Is the Phonak Audéo Sphere Infinio?
The Phonak Audéo Sphere Infinio launched in August 2024 and became even more capable after the October 2025 "Infinio Ultra" firmware update. It was one of the first hearing aids to feature a dedicated on-board AI chip. This chip, called DEEPSONIC, works alongside the standard ERA chip to separate speech from background noise in real time.
Key Features of the Phonak Audéo Sphere Infinio
- Dual-chip architecture — the ERA chip plus a dedicated DEEPSONIC AI (deep neural network) chip
- 53x more processing power compared to previous Phonak models
- Spheric Speech Clarity — trained on 22 million real-world sound samples, able to extract multiple voices from any direction
- AutoSense OS 7.0 — automatic environment detection that adapts to whatever situation you're in
- Ranked #1 for speech-in-noise performance in independent HearAdvisor lab testing, with a SoundScore of 4.58/5
- Up to 10.2 dB of SNR improvement and a claimed 35% reduction in listening effort
- Up to 56 hours of battery in normal mode, but only 10–11 hours when running continuously in "Sphere mode"
Signia Pure Charge&Go IX vs Phonak Audéo Sphere Infinio: Detailed Comparison
1. Noise Cancellation and AI Technology
This is the biggest point of difference. Phonak's DEEPSONIC chip is a dedicated AI processor built specifically for noise cancellation, which gives the Sphere Infinio a real edge in extremely noisy environments — like a packed restaurant or a party — a claim backed by independent lab data.
The Signia Pure Charge&Go IX takes a different approach, focusing on tracking multiple simultaneous talkers and making sense of multi-stream conversations naturally, which is more practical for group settings like a dinner table or family gathering.
In simple terms: if your biggest struggle is a single, very loud environment (a concert, a crowded restaurant), the Phonak Audéo Sphere Infinio is the better fit. If you spend more time following conversations between several people at once, the Signia Pure Charge&Go IX is better suited to you.
2. Battery Life
Battery comparisons here are a bit nuanced because the two devices behave differently depending on how they're used:
- Signia Pure Charge&Go IX: a consistent 39 hours in normal daily use, whether or not you're streaming — battery drain is predictable.
- Phonak Sphere Infinio: up to 56 hours in normal mode, but when the DEEPSONIC AI chip (Sphere mode) is running continuously, battery life drops to just 10–11 hours.
If you plan to use the AI noise-cancellation feature throughout the day, you'll need to think more carefully about charging with the Phonak.
3. Size and Comfort
The Phonak Sphere Infinio's dual-chip architecture makes its body noticeably larger than a standard RIC hearing aid. The Signia Pure Charge&Go IX, by comparison, keeps a compact, sleek design that feels more discreet — a plus for anyone who wants a less visible hearing aid.
4. Connectivity and Compatibility
Both devices support Bluetooth streaming, hands-free calling, and app control:
- Signia's newer BCT IX version offers universal Bluetooth Classic connectivity, making it easy to pair with virtually any phone, Android or iPhone.
- The Phonak Sphere Infinio also supports hands-free calling on both iPhone and Android, but Auracast and LE Audio still aren't enabled as of mid-2026.
One important distinction — the Signia Pure Charge&Go IX comes with telecoil and CROS (single-sided deafness) options, while the Phonak Sphere Infinio ships without either. If you have single-sided hearing loss or frequently visit looped venues like theaters or places of worship, this could be a deciding factor.
5. Price Comparison
Based on typical US market pricing in 2026:
- Signia Pure Charge&Go IX: approximately $2,698 – $3,398 per pair
- Phonak Audéo Sphere Infinio: approximately $3,598 – $4,898 per pair
