Testing, then testing again
The software changes and bug fixes are now complete.
We are in the final phase of testing to ensure it is 100% ready for commercial purposes (testing was reopened after our software changes and bug fixes were complete).
We are fully confident with the production version of the FS-X, in testing it is now consistently delivering over 100 dB in single mode whilst retaining a high level of bass, all without distortion.
A few comments about the ‘First Look’ units have raised questions on air escaping from the rear and the scratch-resistant coating. To answer this, all ‘retail’ units will have airtight gaskets. And all ‘retail’ units will be varnished with UV coating (the ‘First Look’ units were only spray painted), this will ensure they are harder wearing and more scratch resistant.
Fortunately (and unfortunately) when testing and testing, then testing a little more we uncovered a small but important bug that occurs under certain conditions. This bug has now been mitigated but we may need to drop a new, less important feature to avoid a further delay.
This is a bug in the Bluetooth chip which inappropriately detects low power and triggers the (new) audio and visual warnings when playing at max volume. This would occur when the battery level occasionally and momentarily drops below 3 volts (the Bluetooth shutdown voltage), triggering a BT shutdown.
We have mitigated this bug in the software, so that the audio quality is unaffected, but the audio and visual warnings for low voltage are still triggered and do not shut off. Since this is an internal function with the BT chip, it is not in our control. The chip company is looking urgently at a solution, but ultimately, as a last resort, we may have to switch off the warning function.
Once we have completed final software testing, we will be able to provide you with more pictures, videos, a specific timeline and we will resume reviews with professional bloggers and YouTube vloggers.
Your next update will be no later than a week from now, Wednesday 19th August.
All the best,
