Bluetooth
The feature that defines these two models. A phone or a tablet joins the same ears as the intercom and the radio, which is what an officer's seat usually needs and a crew seat usually does not.
507 only
Built & serviced in Lemoyne, PA — by firefighters, since 2009
500-Series wireless
The fully-loaded 500-Series headset: DECT7, Bluetooth, radio transmit, and stereo listen-through, in convertible or under-helmet wear.
Bluetooth is the whole difference. Both models transmit on a connected radio, both carry stereo listen-through, both run 24 hours, and both are rated 24dB. The 507 adds Bluetooth for a phone or a tablet and lists at $1,045 against $945. If no one at that seat needs a phone in their ears, buy the 505.
FHW507.V2 converts easily between overhead and under-helmet wear, so one headset follows a firefighter from the cab to the roof. UHW507.V2 is dedicated under-helmet. Same electronics, same price, same features — this is purely how the headset sits on the head.

Product overview
The 507 models are the top of the 500-Series: everything the platform does, with Bluetooth. That last part is what usually decides the seat. An officer who needs to take a phone call, run a tablet, or bridge a device into the crew's audio wants a 507. A firefighter who only needs the intercom and the radio does not, and the 505 saves $100 a headset.
Everything else is the 500-Series platform. DECT7 gives high-definition audio between crew members instead of the compressed, clipped sound that analog produces once the pump is working. Stereo listen-through feeds the scene back into the cups — the pump, the saw, the officer standing beside you — without breaking the hearing protection seal, and its volume is independent of intercom and radio volume, so it gets set once per firefighter and left alone. Radio transmit lets that position key a connected radio, and any 500-Series headset can also be direct-wired to a portable radio with a FIRECOM portable radio adapter cable.
The difference between the two 507 models is wear, not capability. FHW507.V2 converts between overhead and under-helmet; UHW507.V2 is dedicated under-helmet. Both list at $1,045.
Headsets are a component, not a system. See the WB505R.V2 wireless base station for the in-cab side, 5000-Series digital intercoms for radio and auxiliary integration, and the 505 models or the 503 crew headset for the seats that do not need Bluetooth.
What these models do
The 507 pair is the complete feature set. These are the capabilities that separate it from the rest of the line and the ones it shares with it.
The feature that defines these two models. A phone or a tablet joins the same ears as the intercom and the radio, which is what an officer's seat usually needs and a crew seat usually does not.
507 only
Key a connected radio straight from the headset, so the position that owns the radio traffic is not reaching for a handset while doing something else.
Two microphones feed scene audio into the cups so a firefighter hears the people and equipment around them without lifting a dome. Listen-through volume is independent of intercom and radio volume.
FHW507.V2 converts easily for either overhead or under-helmet wear. UHW507.V2 is dedicated under-helmet. Same electronics and same price either way.
FHW / UHW
All 500-Series wireless headsets carry a 24dB noise reduction rating. Sirens, an unmuffled exhaust, and a pump at working pressure stop being the reason a message gets missed.
All 500-Series
Lift a headset off the charging cable and it powers up and connects within six seconds. A full charge carries 24 hours of talk time, which covers a long incident without a battery swap.
All 500-Series

Headsets are configured with the FIRECOM Configuration Utility, so features can be enabled, disabled, and standardized across a fleet instead of set headset by headset.

Before you request a quote
At the officer's seat, usually yes — a phone call, a tablet, or a device patched into the crew's audio is a real part of that job. At a crew seat it is usually money spent on a feature nobody will use. Most departments buy a mix: 507s where the phone matters, 505s everywhere else.
Only how it is worn. The FHW converts between overhead and under-helmet; the UHW is dedicated under-helmet. Identical electronics, identical features, identical $1,045 list price.
Yes, with the FHW507.V2. FIRECOM's convertible models convert easily for either overhead or under-helmet wear, so a firefighter carries one headset instead of a cab headset and a fireground headset.
For intercom, no — the wireless side needs a WB505R.V2 base station. For radio, yes: any 500-Series headset can be direct-wired to a portable two-way radio with a FIRECOM portable radio adapter cable, which is how crews stay on dispatch once they are away from the apparatus.
