User questions & answers

Question:	Is the "one size" option the dual unit version? the model number in the technical details indicates a single unit but dual units are pictured
Answer:	2
Question:	Will this connect (mesh) with other bluetooth brands, or only sena? Thx in advance for your answers
Answer:	Hi, All of the CARDO current range can pair via the Bluetooth intercom.
Question:	How does this work with sena 20s
Answer:	This package when I ordered it is for the 4+ which has the JBL speakers. This is what you want as they are better audio quality. It should say JBL on each speaker mesh
Question:	Is this sena 30k-01 (dual) the same as a sena 30k-01d
Answer:	The Freecom 4+ Duo (notice the +) comes with 2 sets of 40mm JBL speakers. You can also order them separately from the Cardo website for about US$50.
Question:	Is it only 100 Meters
Answer:	You get an universal mount that sticks on the outside of the helmet and than you run the lines for the speakers and microphone through the side under the cheek pads into their places. You have to have in your helmet 2 dimples that the speakers would sit in (under the cheek pads in the area around your ears).
Question:	Having pairing issues, does this pair with more than one device? Also if it freezes up how do I reset it
Answer:	20 if you grind it to 16 it will be more like an Asian grind
Question:	How many riders can connect
Answer:	Wusthof Gourmet knives are laser-cut stamped knives, produced from high-carbon stain-free steel. Wusthof Classic are forged knives, heat-molded from one piece of specially tempered high carbon stain free steel. In other words both the materials and the process to make the Classic are more expensive, so the finished product is more expensive. Both lines offer knives that will provide years of use with proper care. If you've not personally held these knives I would strongly recommend doing so before making your purchase.

User questions & answers

Question:	Does it work on a half helmet
Answer:	You can mount it on a half helmet but I'm not sure how well this can work. Some half helmets don't cover your ears, which will make it difficult to hear since the earphones are supposed to mount inside the helmet right where your ears would be. Also, you microphone will be completely exposed whereas on a full-face helmet, the microphone will be inside the helmet and blocking some of the wind noise. Hope this helps.
Question:	Is Amazon an Authorized Reseller of this item? The manufacturer will not honor the warranty from a non-authorized reseller
Answer:	The item seller is "David's Tools," not Amazon. You'd have to ask "David's Tools" if they are an authorized retailer.
Question:	Can 3 of us use these at the same time and all 3 talk to each other? Is there a push to talk, or is it live all the time
Answer:	Hi, yes 3 can use at the same time. I used with 4, and think that's the max. Also it's live, once you turn on its live, just talk. My bike is fairly loud and it works great.
Question:	Is this item waterproof
Answer:	It is water resistant, I've gotten drenched in the rain more than once and it is fine. It is not waterproof. Mine accidentally got submerged, game over.
