① This data was the result of a test that was conducted using OpenMove paired with iPhone 7 (version: ISO12.3.1).
Test conditions: Paired OpenMove with iPhone 7, adjusted to the standard EQ mode, played the white noise file with a 44.1kHz sampling rate and 24bit depth in wav format through the IOS music player, and set the volume to around 80% of the maximum volume.
Test content: OpenMove battery was fully discharged and then charged to 100%. The audio file was played until the headphones stopped playback. The duration time was counted as the continuous playback time of the headphones.
The test result showed that the OpenMove had a continuous playback time of up to 6 hours. In actual use, battery life depends on device settings, environment, usage, and many other factors.
②IPX5: This rating applies to items that are protected against ingress from jets of liquid.
Test conditions :
a) OpenMove was placed on a testing table.
b) A strong jet was used to project water in all directions of OpenMove.
c) The inner diameter of the jet was 6.3mm, and the water flow was 12.5L/min.
d) The distance between the jet and OpenMove was between 2.5m to 3m, and the duration time was 3 minutes.
After the test, OpenMove functioned normally.
IP5X: This rating applies to items that are protected against ingress from dust.
This was tested using a 1.0 mm access probe and by inspection to ensure any dust that enters would not interfere with the part’s functionality.
1. Testing on access to hazardous parts: Used a metal wire of 1.0 mm to probe some hazardous parts such as gaps of the shell.
2. Testing on the entry of solid foreign objects:
a) OpenMove was placed in a dustproof box with talc powder floating in the box. The amount of talc powder was 2kg per cubic meter of the test box volume.
b) The talc powder was filtered through a metal square-hole sieve. The diameter of the metal wire was 50μm, and the mesh size was 75μm. The amount of talc used was 2kg per cubic meter of the test box volume and the material was used within 20 times.
c) The duration time was 8 hours.
After the test, there was no dust deposit inside the shell of OpenMove, and OpenMove functioned normally.
③Compared to the 6th generation, the 7th generation has higher waterproof standard and 50% less sound leakage.
