well time to test "abroad" shipping ...
i wanted to upgrade my Fiio RC-BT bluetooth module for my FA1 and seeing they launched their UTWS1 modules ... i pondered ...
BT5.0 and no wire between the 2 modules (can act in a right master left slave or both master, which is TWS+ function ) use the QCC3020 Qualcomm chip ... but what the flying F, i get a "deja vu" heavy feeling

ok pricing, if i order on Aliexpress : 44chf~ if i order locally: 86chf and same 15-22 days delivery delay because "not in stock locally"
now for the "deja vu" (and that's a long term "deja vu" ... the BT20 is around since quite a while) ... TRN BT20 and the subsequent BT20S, same shape same specs same chip .... ohohohoooh ... (obviously taking them with MMCX connector)

pricing: 27chf~ a little search : reviews mostly good for both, check with Fiio : their UTWS1 is manufactured by TRN (seriously?) and they justify the +17chf (well not the +59chf for local ) by assuring they did tweak the chip for their specification (cross review attest the BT20S has a little bit more floor noise but barely noticeable)
now the wait game begin .... wish me luck
less tech ...

not a fan of white mask thus:
reusable silicon mask (facepiece is silicon), my workplace will reopen around 8th june and mask will be obligatory, i consulted with the competent organisme ruling norms for that in Switzerland and that mask fit the bill provided i use FFP2/N95/KN95 filter insert (i ordered 30 of them, given my workplace they should be ok for 1 up to 3 days per insert depending on frequentation)
N100 = KN100> N99 = FFP3> N95 = KN95≈FFP2> KN90> FFP1
KN95 masks mainly decrease over time, with an average reduction of 1.2% at 8 hours per day, and after 33-40 hours, it will drop to 90%, which is equivalent to the level of N90. It is recommended to replace the filter element within 1-3 days.
bad news ... i will have to shave ...
