Classroom Timer Com

I use the product daily in my high school classroom. It works great. I like the timer feature on this model. It's good for timing discussion times between students, etc. For some reason, the students think the green laser is especially cool.

Fits perfectly in the classroom.

We have been using these in a k-5 classroom setting. Never had a problem.

At first I was concerned about having to navigate a user interface each time I wanted to use my RS-232/Com-3 which by the way is missing on many new computers. In 5 minutes, I had loaded and configured Keyspan which operates in the background after config- downloaded all of my waypoints from my Garmin GPS and had the points up on GoogleEarth in a jiffy. (Used EasyGPS free download; don't forget to config EasyGPS for Com-3)

This product is used both with the Clear-Com wired IFB (TR-50) and with the Clear-Com wireless IFB receiver (PRC-2). It is the right connection type for these two products. This headset can be used with any Clear-Com 4-pin XLR connection with an adapter available by a third party (may be custom). Also, this headset can be used with any HME DX Wireless beltack if you get the HME HSI6000 adapter (to get from mini-din to 2.5 mm) and a third party 2.5 mm to 3.5 mm adapter (several available). For the other people that provided low ratings because it was not the correct headset, it is not fair to mark down the product just because you bought the wrong one!

I'm purchasing these to replace 30-year-old Clear-Com headsets. The mic sounds good and overall audio quality is good. And these are fairly comfortable wearing them for long periods of time.

Light and airy! Don’t even know they’re there. Excellent sound quality and clarity as well. I have the Open Run and Open Com as well. The Trifecta of audio! And they look great and have a small profile.

We have several of these deployed and the Com Port Retention makes life easier for our clients - and we've never had a failure. So we are quite happy with this product.

used in an 18,000sq Ft. event space in San Francisco. I was completely blown away with its performance, range, and clarity. Wow factor! I've been in production for 20 plus years and have used half a dozen different Com systems over the years. Wired systems always tend to have a ground hum or some interference issue. Older clear com systems, wired or wireless, same. The wow factor for me with this Hollyland set up was that I couldn't find a note of interference in this event space. Why is this amazing? This event space is inside a mall in the heart of downtown SF, has 8 wireless mics, over 20 High powered Cisco Meraki AP's, movable air walls, a hallway that wraps the space, and the control room is inside a soundproof booth enclosed in glass. The brain and antenna booster were installed in the control room, on house power, and routed through the Black Lion power conditioner (not sure if this helped?) When used with the antenna booster (extra $150), I walked every part of the venue from the coat check closet to the bathrooms (farthest points) and had no drop out or loss of audio fidelity. I don't even use the mute button, I simply move the mouth piece up and down. The belt packs on a full charge lasted over 8hours! To compare this system to a Clear-Com system simply isn't fair. The Free-speak II beltpack is over $2,000! The brain unit is over $11k ! Pros: -affordability -ease of use- plug in and turn on and it works -battery powered option for base station (batteries not included) -belt packs have internal rechargeable batteries! -amazing coverage and clarity -well made and fairly comfortable -expandable with another base station over short or long cat5 run -soft pouch for each headset- and extra ear piece covers included! Cons: -having to hold the mute button to talk (I don't use this feature. I leave live and mute by lifting headset mic into the up position and talk by moving it back down) -does not come with a carrying case
