The same item details list impedance 32 ohm, driver 10 mm, Bluetooth range 20 m and latency 60 ms, which conflict with the maker page or repeat the values on TOZO A1 listings, so no other value is taken from that listing.5Regulatory filingfccid.io/giteki/220-JP8106Read 21 October 2026Japan Giteki certificate 220-JP8106 of 2024-09-26 to Shenzhen Worgo Technology Co., Ltd. lists T13064 with nine other T13 model numbers, so T13064 is a real TOZO model code.
