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.

Very useful. The range is a little bit on the low side, and it doesn't reconnect automatically after it goes out of range.Other than that it works well and the battery last a long time.

Installation was easier for the shoei helmet than for the hgc.An excellent intercom, with clear and powerful sound. We can talk clearly to each other on the highway at high speeds without interruptions. The battery life is very long. overall very happy and extremely well packaged, safe and fast delivery.
