Retevis RB85 long range two way radio features a DNN noise reduction module with an AI chip, eliminating ambient noise for clear communication in noisy environments. Its high power ensures extended range and reliable signal in crowded or rugged areas. It's widely used in noisy factories, warehouses, schools, restaurants, racing venues, etc.
Retevis RB85 noise reduction walkie talkie has a built-in noise-canceling chip, which can achieve deep learning of more than 400 million voice data samples, including 200 million foreign language voice samples. After the intelligent noise reduction is turned on, the noise reduction chip detects the noise according to the current environment. The noise reduction chip outputs a reverse noise sound wave to eliminate the noise so that the signal receiving end can only hear clear human voices.
This bundle includes Retevis EEK019 AI active noise cancelling 2 way radio headset, which filters out ambient noise, delivering clear human voice communication. It features a magnetic clip, double PTT buttons (large for gloves), and a 180mAh rechargeable battery lasting up to 60 hours. The earpiece also comes with a USB-C charging port for easy recharging. The detachable C-type ear hook fits both ears and can be replaced with other accessories.
Enjoy long-range communication of up to 2.5 miles (approximately 4 km) in open areas with high power output. (Please note that range is for reference only.) The radio also has a detachable antenna that can be replaced with another high-gain antenna to reach further.
Retevis RB85 rugged 2-way radio features a durable shell, is resistant to shock, vibration, extreme temperatures, and water splashes, and continues to function normally even after a 2-meter drop.
A 2000mAh battery provides up to 72 hours of standby time. Conveniently charge your two way radio or batteries with the included USB charging base.
Utilize the 9-level VOX feature to adjust sensitivity according to your environment. Higher levels increase sensitivity, allowing you to receive even weaker signals outdoors.
This radio features both local and remote alarm functions, enabling you to prepare for emergencies and request assistance from your partner.
There are anti-slip patterns on the sides and back of the RB85 two way radio, which can help prevent dropping your walkie talkie.
Noise reduction two way radios are needed for a variety of reasons. They help reduce background noise and interference from other radio signals, which can be distracting and disruptive to radio conversations. They also help improve the clarity of radio transmissions, making it easier for users to understand what is being said. Finally, noise reduction two-way radios can improve radio reception range and reliability, allowing users to stay in contact over greater distances.

This is a really nice radio, after two days with this radio at work and using on a repeater I can recommend this radio. The range has doubled on both repeaters and simplex and the clarity is top shelf. The only thing I would change and strongly recommend is getting a better tuned antenna for the frequencies you use. I’m using a smiley sma-F antenna and honestly I think the antenna looks perfect on the radio .The charger is USB and you will need an adapter or something to plug it in to but I think it’s safe to say everyone already has this I’d love it if retevis made it to where I could plug a usb cable in to the battery instead of having a charger base like my Radiodity GS-5B in the picture.
I was able to communicate with my other user in an urban environment. Both users were able to communicate through the radio in 2 different scenarios. Scenario 1: We were not within the line of sight, 10 blocks apart from each other, standing by the window with tactical antennas extended all the way out. Scenario 2: Radio comms were made inside an office building, 10 stories apart from each other, while 1 person is riding in the elevator and the other user stayed inside the office. Good product! The product feels sturdy in hand! I'd definitely recommend this to others!
I fly hot air balloons and I use two way radios to communicate with my ground crew. The sound is crystal clear. I didn’t need the earpieces or for them to be waterproof so I bought the less expensive ones. They are lightweight and not at all bulky. You won’t be disappointed!
Excellent radios, we use them in theater for comunication between House Manager Stage Manager.
Range is really good and it is wireless great quality
This is a winner GMRS radio ! Was easy to program with CHIRP, fits your hand comfortably . The receive and transmit are very good. Getting into my local GMRS repeater over 20miles away with the supplied antenna (will be putting a SMILEY antenna on them) . Not getting the full 10 watts out, but well over 6.5 . I've had Motorola, Harris and other commercial rigs, this radio can hold its own, NO special programming cables or antenna connectors needed... A little more pricey than others but I think it was worth it.
These radios work great, clear audio and great distance
