This beige CO-3-Kit from Point Source Audio is an entry-level headset microphone with a 4-pin cW-style Hirose connector for Audio-Technica wireless transmitters. It is designed for speech reinforcement in presentations, church liturgy, lecturing, and other applications where the speaker requires a hands-free microphone solution.

The kit features an omnidirectional microphone in a low-profile headset that is worn on the left ear. A reversible dual-ear mic clip is included that provides more secure positioning, if desired, and allows the mic to be worn on the left or the right ear. The omnidirectional polar pattern offers a forgiving 360 degree pickup pattern. The fixed-boom design reduces speech-popping sounds and voice overloads by conveniently placing the mic near the mouth and keeping the capsule away from potential clothing and fabric noise. The kit also includes a storage case, cable clip, and 6 windscreens for the CO-3 microphone.

The forgiving omnidirectional pickup pattern makes the headset easy to wear and is well suited for use low to moderate noise environments.

A rigid boom with a fixed length offers a sturdy, unobtrusive, and low-profile design. This makes the mic and headset barely noticeable, especially from a distance.

Related Questions and Answers

Q: 1. How would you adjust the shutter speed on your camera while using this flash (YN685)? I have a D600 camera. Thank you.

A: Generally, the shutter speed would need to be at or below the flash sync speed of your camera body. In the case of the D600, you would need to be at or below 1/200th.

Q: 2. Can we trigger Yn-560-IV using this flash?

A: The YN-560 IV has an optical slave trigger so it can be set to fire when any other flash goes off in the same area. It's slave can be set to ignore pre-flash common when operating YN685 in TTL. But there is no RF communication between the 2 units.

Q: 3. Can you confirm the type of port used for the external battery? Is it actually a Canon style port?

A: Yes it is a canon style port.

Q: 4. I have several YN560-IIIs with a 560-TX controller. Great system. They work with my Sony A7iii. Now I want to add some HSS. Any idea if the YN HSS will sync with the Sony?

A: Unfortunately, Yongnuo does not have any TTL flashes in their lineup compatible for use with Sony's TTL automatic flash system that would provide High Speed Sync capabilities with Sony cameras.

Q: 5. will any external speed light battery compatible with canon work with this flash?

A: Being that this flash uses the same HV port as Canon speedlites, you could use an external battery pack as long as it offers a CZ type cable such as those from Quantum, Lumedyne or Bolt.

Q: 6. Will these work using an older Photogenic powerlight 375 with a Canon 7D or a 5Ds camera?

A: The Vello Freewave LR would not be compatible with the older Photogenic Powerlight 375 monolights due to their higher sync voltage.

Q: 7. Can I fully control the speed light settings from a Yongnuo YN-622N-TX wireless controller mounted on camera?

A: Yes, it is compatible and you can control from the camera the flash with the YN-622But the flash you picked is for Canon and the correct 622C is, Yongnuo YN-622C-TX E-TTL Wireless Flash Controller for Canon B&H # YOYN622CTX MFR # YN-622C-TX

Q: 8. I have canon 80d if i buy 2 yn 685 flashes then which trigger reciver i need to buy?

A: The best solution is to buy the Yongnuo YN685 Wireless TTL Speedlite and Wireless Flash Controller Kit for Canon Cameras plus one additional YN685 (for Canon). The Flash Controller included in the kit does a great job of controlling the pair of YN685s. The YN685 flashes include the radio receivers (built in), so you do NOT need additional YN622 transceivers.

Q: 9. Can I control multiple (say 3) off camera YN-685s, with just using YN-622C-TX and without requiring all of them on YN-622C receiver?

A: You don't need the YN-622C receiver to control these flashes. They have the radio receivers built into the flash.

Q: 10. i have D7100 and want to buy YN68 will it work with D7100 CLS system, or should i need YN622 tx ?

A: My understanding is that the D7000 series CLS system uses the popup flash for controlling the external flash. (Popup in Commander mode, external flash in Slave mode) The YN685 is controlled via radio signals, not optical /light/popup-flash. The protocol ( language ) used by the radio signals is Yongnuo-only, so you need a Yongnuo transmitter attached to your 7100 hot shoe. The YN-622N-TX is transmitter only (with LCD for setting flash outputs/ratios and mode), while the YN-622N can act either as a receiver or a transmitter (but lacks the TX's LCD capabilities).
