The sound produced by the internal speakers can be increased or decreased in 4 levels with a maximum output of 82 decibels.
The configuration menu is fully voice guided and allows you to change some functions:
- RELEASE TIME
One of these functions is the release time that can either be slow or fast, whereas the slow one is used for indoor shots. Whereas the echo of the shots can create sound shocks.
- VOLUME BALANCE
Next up, is the volume balance between the ears which can be put on seven different settings. This is for example useful if you have hearing loss on your left ear, you can amplify the sound output of the left ear pad to regain your situational awareness.
- EQUALIZER & SILENCE MODE
Above an equalizer mode which are the 4 different sound levels we talked about earlier, this system also features a silent mode which shuts off the external microphones.
In total wearing the headset as it comes, gives you an SNR or signal-to-noise ratio of 28 decibels. If you require a higher reduction of decibels you can also wear earplugs underneath a headset which brings the total up to 39 decibels.
Remind that when it comes to volume every 3 decibels is a doubling of the sound energy. So 11 decibels is quite a lot. This is all good in terms of protection, but a problem that it usually brings along is that the output of the speakers is reduced too much as well. For this the system features an "ear plug mode", this enhances the speaker output by 6 decibels, so you can keep your communication and situational awareness with earplugs on.
The headset in total weighs 335 grams with batteries included. it can operate between -40 up to 55 degrees Celsius and it has an average runtime of 200 hours, but our supplier with much more experience says it can go even up to 300 hours.
7. COMTAC XPI IMPROVEMENTS COMPARED TO COMTAC XP
Besides these features the ComTac XPI has some improvements compared to its predecessor the ComTac XP (EU) or the ComTac III (USA).
- A better sealing of the battery compartment against moisture.
- A better sealing of the board against salt water.
- The removal of pressure points on the headband which are especially noticeable when wearing it underneath a helmet.
- It has an extensive voice guide menu.
- The volume of the connected radios can be changed and the microphone gain can be adjusted as well.
- With the ear plug modes, the volume of the connected radio is enhanced as well. They also added a silent mode where we talked about earlier which shuts down the external microphones.
Next up is the PTT.
8. PTT FEATURES
It has a button with a very positive feel that ensures you are transmitting even with thick gloves on.
The PTT has also been tested and approved for a minimum of 100,000 plugins with the J11 cable.
Now that we have covered all of this, let’s have a little demonstration of the headset. For this we recommend you to watch the video since this is an audiovisual demonstration. The demonstration itself starts at 9:48.
10. FINAL THOUGHTS
- The headset enhances your situational awareness allowing you to hear sounds you would normally not perceive and this while blocking explosions very well. This is obviously an advantage.
- It is very easy in use, reliable, tough and always offers a clear sound. We never had any issues with radio communications like calls not coming through or sending out.
- It is comfortable to wear for a couple of hours and would apparently be even more comfortable with gel cushions.
- The ComTac XPI is definitely a buy once cry once product since they are expensive but they will probably last you your lifetime.
