Baru pasang Cardo Spirit after ding-dong so long reviews saying low sound quality, not loud etc and all, but I made the pucahse with low expectation, just for the sake of having Cardo (app, support, firmware update).

Pasang dekat my LS2 Infinity 2 Carbon (interesting helmet...), it has Cardo intergration, so has the correct cutout location at the cheek pad insert, has a cavity prepared to put the wires/connectors in. I hate boom mic, looks like org ambil order dekat MekD, so i tried the other mic, placed it beside the cheekpad.

Lo and behold, speaker is so fucking loud (im setting it at 20% only), sounds OK and pretty acceptable. Bass hilang masa moving but that is sound principle saja pun. Jgn la compare with wired higher end IEM or headphones (been there, done that, so I come prepared with experience), but it is totally acceptable, like the stock FREE earphone you get with buying iPhone or Samsung back then.

Mic was suprisingly good, ive made few calls, on the bike, going 80kph and ppl said i sounded normal and was suprised to learn im talking to my helmet, while riding. Now can join online meeting while ular, haha!

Keep in mind, ini open helmet ooo
