TRN BT20S Bluetooth IEM Module


Be the first to review this product

Bluetooth module which runs Bluetooth 5.0 and runs both aptX and AAC codecs (works well with both Android and iPhone iOS)!

The TRN BT20S is a superb TWS true wireless bluetooth module for your MMCX IEMs!

An awesome upgrade to the previous TRN BT20 version, the BT20S is upgraded with aptX + AAC codecs with Qualcomm's QCC 3020 chipset, has longer playback time of 8 hours, has a textured surface to reduce slip from your hands, a nano coating to improve water resistance (allowing it to be used for sweat intensive sports), and DSP noise reduction!

*do note this may not work well with IEMs with larger power consumptions.

If we carry the earphone you use, we can test them out for compatibility.

Alternatively, you are most welcome to our showroom to test!
