Cardo Spirit HD Duo 通信系統雙包

If you just want to listen to music while riding and not spend too much this is a great product. Build quality is really good and it was easy to install. My helmet already had the holes for the speakers ready tho. Sounds really really good imo, and very convinient to use. Google assistant or whatever you have works as well so you can ask it to put a specific song, call someone or whatever you want without taking out your phone.

Now, the intercom feature is gonna be great if its for you and your backpack. The sound quality is pretty good and it filters most of the noise from the wind, engine and so on. But the range isnt great, usable if you're riding pretty close, you don't have to be tailgating the other person but as soon as you get separated a bit you lose the connection. 100-200m is pretty reliable id say, further from that depends on the terrain and traffic around you I imagine. But this is how the product is advertised as well so im not taking away stars for that, im just mentioning it so you know what you're buying.

Very good sound, very good volume - loud even at high speed, good battery. Love it.

Great entry level intercom, very handy use, good sound quality and affordable price.
