What Audiodo does
Audiodo is a Swedish audio software and algorithm company headquartered in Malmö that develops hearing-based audio personalization technology for the consumer headphone, earbud, and portable audio player markets. Its core technology combines a 3-minute Pure Tone Audiometry hearing test with psychoacoustic modeling and real-time compensation algorithms that adapt audio output to each user's unique frequency sensitivity profile, achieving a claimed 95% accuracy. The portfolio comprises six SoC- and DSP-embeddable solutions: Personal Sound (the flagship personalization algorithm), Equalizer, Audiosphere (spatial audio with four presets), Personal Transparency (PSAP-style hear-through), Personal Hearing (OTC hearing assistance), and Shield (WHO/EU EN 50332-compliant volume capping). The ASPEN low-level SDK enables integration across iOS and Android companion apps using BLE and Bluetooth Classic.
The company operates a pure B2B technology licensing model with no direct consumer sales. Revenue is generated through royalty-bearing licensing agreements with consumer audio OEMs that embed Audiodo's algorithms in their hardware and activate them through their companion apps. The partner portfolio spans 10+ brands across price tiers — mass-market (Nothing, CMF by Nothing, Skullcandy, Tribit, Fresh 'n Rebel, Meizu) and premium audiophile (Noble Audio, PSB Speakers, Astell&Kern, Nuarl, Nocs) — supported by chip-level alliances with Qualcomm, BES (Bestechnic), Bluetrum, Airoha, and Knowles. Audiodo has accumulated more than 2 million user hearing profiles across 15+ product models, providing a proprietary data asset for algorithm refinement. The company is privately held, has 11-50 employees, and maintains field-sales offices in Shanghai, Seoul, and the Netherlands alongside its Malmö headquarters. Leadership includes CEO Jan Weber and co-founders Roger Martinson and John Philipsson.

Audiodo competitors and assessment
Company assessmentDirect peers
- Dirac: Swedish audio software company Dirac provides digital audio optimization (room correction, soundstage, bass enhancement) integrated into headphones, earbuds, automotive, and home audio. Competes with Audiodo in OEM audio software licensing, particularly for spatial audio and sound enhancement features.
- Sonarworks: Sonarworks offers SoundID, a sound personalization technology licensed to headphone and earbud brands, based on user preference and hearing profiles. Like Audiodo, Sonarworks is a B2B audio personalization company targeting the same OEM partner channel with comparable SDK/App integration into consumer audio products.
- Mimi Hearing Technologies: Berlin-based Mimi Hearing Technologies builds hearing-based audio personalization software embedded in consumer earbuds and headphones (e.g., Skullcandy, Cleer, Doppler Labs). It is the closest direct competitor to Audiodo, offering a near-identical proposition: a quick hearing test, a personalized hearing profile, and SoC/SDK integration into OEM mobile apps.
Broad incumbents
- Apple: Apple offers Personalized Spatial Audio, Adaptive Audio, and Hearing Test features in AirPods Pro 2 and iOS 17+, built around individual hearing profiles. Apple is both a potential competitive threat to Audiodo's OEM partners and a benchmark for what personalization features consumers expect.
- Bose: Bose is a major incumbent consumer audio brand whose CustomTune technology calibrates sound to individual ears in products like the QuietComfort Ultra Earbuds. Bose represents the kind of vertically integrated competitor that may displace third-party personalization providers like Audiodo in flagship-tier products.
- Sennheiser: Sennheiser's consumer audio division (now Sonova-owned) competes in premium headphones and has explored personalized sound features. Represents both a potential Audiodo partner in the audiophile tier and an incumbent competitor with in-house audio engineering capabilities.
- Sonova: Swiss hearing aid giant (Phonak, Unitron, Sennheiser consumer audio) and major player in the OTC hearing aid category post the FDA 2022 rule. Sonova is the most consequential potential incumbent competitor in Audiodo's OTC hearing aid pivot (Personal Hearing), with deep audiology and regulatory infrastructure.
- GN Hearing (Jabra Enhance): GN Hearing's Jabra Enhance line competes directly in the OTC hearing aid category Audiodo is targeting with Personal Hearing. GN brings established audiology IP, FDA-cleared devices, and established retail channels that Audiodo's consumer-electronics distribution does not yet match.
Emerging players
- Creative Technology (Super X-Fi): Creative's Super X-Fi technology personalizes spatial audio based on head/ear mapping and ships in Creative headphones, earbuds, and as an SDK. It is a partial-overlap competitor focused specifically on the spatial audio dimension of Audiodo's Audiosphere offering.
- Ossic: Ossic developed 3D audio calibration software for headphones. While the original hardware company is no longer operational, the broader category of HRTF-based personalization startups reflects the same trend Audiodo serves — niche players attempting to commercialize individualized spatial audio at consumer scale.
