BOSE A20 HEADSET LEMO 6 PIN PLUG W/ BLUETOOTH ELECTRET MIC
Excellent product. Excellent service.
Best headset and best service on the planet!!!
I purchased a LEMO plug Bose after purchasing and using a Lightspeed Tango headset for 7 months. Although the Lightspeed offered good ANR performance I had no idea how much better the Bose would be for my airplane with a geared engine. My motivation for purchasing the bose was the Lightspeed is difficult to get the ear cup location just right, it feels bulky. It didnt seem like I could adjust the headset to fit. From a comfort standpoint, the Lightspeed does have a slight edge with the soft ear pads and less clamping force. But I believe the less clamping force reduces the passive noise reduction. The major reason for seeking a different headset is do not like the microphone and side tone of the Lightspeed. Both in transmit and intercom, the lightspeed is not clear and seems to have a delay. Back to the Bose, it is worth every penny and wiring the LEMO jack was straight forward- Im very glad I did it.
I fly in a Skyhawk a lot and have used a DC Pro X for the past two years. The Bose headset is a bit more money, but has at least twice as good noise cancelation and better Bluetooth controls. Both headsets work very well though and I highly recommend buying the best headset you can afford.
this headset is second to none very clear super sound and the blue tooth works so good that everyone thinks i am in the office
Don’t waste your money. After 5 hours of flying, my ears really hurt from the pressure of the cups. And this is the third time I’ve had to replace the foam filled ear cups, as the elastic cloth holding the foam cup to the headset keeps tearing. Bose may be known for high end audio equipment, but they have much to learn about aviation headsets.
Yes, the battery box for the Lemo version of the Bose A20 will accept the included AA batteries. This will allow the batteries to power the ANR if the headset is being used in a Dual GA equipped aircraft with passive adapter part # 11-08741. No additional battery box is required.
Yes, the Bluetooth feature will stream both music and phone calls to your headset from your device (ie, iPhone, iPad, Android, etc).
Six pin Lemo is the connection plug style. This type of plug is a single connector, and uses aircraft power to activate the ANR. This differs from the more common dual GA plug style, in which there are two male plugs that go into the aircraft jacks and requires AA batteries to run the ANR.
The batteries will only be used in the instance that the LEMO connector stops supplying power. The headset will always use ships power if available, and resort to the batteries as a backup. They can also be used if an adapter, Part # 11-08741, is used to use the LEMO Style headset in a airplane equipped with dual GA female jacks.
Unstretched the coiled portion is approx 14-75 inches. It can be stretched over 6 feet.
