4. Testing Methodologies

4.1 Functional Testing

Functional testing was conducted to ensure the basic features of the product worked as expected. We developed test cases for the following scenarios:

• Bluetooth pairing with various devices

• Audio playback, call functionality, and microphone quality

• Volume controls and touch sensitivity

• Battery life testing (standard use, heavy use, standby)

• IPX7 water resistance tests (submersion in 1 meter of water for 30 minutes)

4.2 Performance Testing

Performance testing measured the responsiveness, stability, and endurance of the product. Metrics included:

• Latency in Bluetooth connectivity

• Audio clarity at varying distances (up to 10 meters)

• Consistent playback over long periods (4+ hours)

4.3 Usability Testing

Usability testing focused on user experience, ensuring the product was easy to use and comfortable. We collected feedback from a sample of 20 users:

• Comfort during extended use

• Clarity of touch control instructions

• Ease of Bluetooth pairing

4.4 Durability Testing

Durability testing simulated long-term usage and harsh conditions. This involved:

• Repeated dropping from a height of 1 meter

• Water exposure tests

• Stress tests for battery degradation after 50+ charge cycles

5. Test Results

5.1 Summary of Results

Test	Pass/Fail	Issues Detected
Bluetooth Connectivity	Pass	None
Audio Quality	Pass	Minor distortion at maximum volume
Battery Life	Pass	10% faster drain during heavy use compared to specification
Fit and Comfort	Pass	User feedback: comfortable, but slight ear fatigue after 5 hrs
Water Resistance	Pass	None
Compatibility Testing	Pass	None
Durability Testing	Pass	None

5.2 Issues Identified

1. Audio Distortion: Slight distortion at maximum volume when used with certain Android devices. The root cause appears to be device-specific.

   • Resolution: Firmware update planned to equalize audio performance across devices.

2. Battery Life Deviation: The battery drains 10% faster than the advertised 6-hour playback during heavy usage (high volume, frequent calls).

   • Resolution: Optimization of power management in the next firmware update.
