There’s connection for 3.5mm audio and 2.5mm balanced audio and USB C. I connected a pair of TIN HI-FI T2’s via the 2.5mm balanced audio jack and there was definitely an uptake in volume and clarity. The TIN T2’s have always been a cracking pair of IEM’s but now they’ve been given a shot of audio viagra.
