Connected audio issues are rarely about a single feature.

They emerge in the moments between connections, during real customer journeys, and under changing conditions.

Nextgen focuses on the moments where connected audio products are most likely to fail.

Connection Reliability

Ensuring stable, uninterrupted connections across devices and environments.

Wireless earbuds connected to a smartphone
  • Pairing, bonding and reconnection
  • Multipoint and device switching
  • Bluetooth / Wi-Fi coexistence
  • LE Audio and Auracast journeys
  • Companion app and firmware interactions

Listening Experience Quality

Delivering consistent, high-quality audio without interruptions.

Headphones with audio waveform
  • Playback continuity and dropouts
  • Call-to-media transitions
  • Latency and synchronisation
  • Audio routing and channel consistency
  • State recovery after disruption

Software & System Resilience

Validating software updates and long-term stability across the entire ecosystem.

Connected device firmware update
  • Firmware and OTA update regression
  • Long-duration stability and endurance
  • Repeated customer journeys and stress testing
  • Cross-device and platform testing
  • Regional and product variant coverage
Our automated approach replicates real-world conditions to uncover intermittent issues, capture the right evidence and give engineering teams complete confidence.

Automated stress testing of real-world journeys

Replicate complex customer behaviour, repeated cycles and adverse conditions to expose intermittent issues traditional testing misses.

Deep, synchronised evidence

Correlate Bluetooth, RF, audio, video and system data to see the full picture and reproduce issues every time.

Faster issue resolution

Engineers get the right data to quickly understand and prioritise issues, identify the root cause and accelerate resolution.

Reduce risk and cost

Find problems earlier in development, avoid late surprises and reduce costly rework and warranty issues.

Scalable, reliable and always-on

Run automated tests 24/7 across multiple configurations, products and software versions.

What our customers say

“We’ve been able to accelerate our OTA delivery process, while the pre-flight testing gives us greater confidence in every release.”

Earbud OEM   |   QA Manager

From customer experience to engineering insight.

Our proven framework combines automated stress testing, synchronised evidence and engineering insight to find issues earlier and resolve them faster.

1. DISCOVER

Automated stress testing

Automated listening journeys replicate real-world customer behaviour under stress to uncover intermittent failures before they reach your customers.

  • Pairing & reconnection storms
  • Multipoint & device switching
  • Long-duration streaming
  • RF interference & coexistence
  • Firmware updates under stress

2. CAPTURE

Synchronised evidence

Capture all relevant data in sync so each issue has accurate context and can be reliably investigated and reproduced.

  • Bluetooth logs
  • RF traces
  • Audio measurements
  • Video recording
  • Metadata & system logs

3. RESOLVE

Engineering insight

Turn complex, intermittent issues into clear engineering insight so teams can fix the root cause and prevent regressions.

  • Root cause analysis
  • Faster debugging
  • Regression prevention
  • Release confidence
  • Better customer experiences
