新一代带遥控麦克风的助听设备
2-in-1 Remote Microphone & TV Streamer: The compact mini-transceiver can be clipped to a speaker’s lapel in a noisy room (capturing voices clearly up to 100 feet away) or connected directly to a television using a 3.5mm audio cable to stream crisp TV dialogue straight to the headset.
16ms Ultra-Low Latency: Utilizing rapid digital sound transmission, it achieves a nearly instant 16ms response time. This ensures that lip movements on a television screen or face-to-face conversations match perfectly with the audio, eliminating annoying echoes or sync delays.
16dB Digital Noise Reduction: Intelligent sound suppression filters out background rumble, clattering, and ambient environmental distractions while isolating and elevating human voice frequencies.
Ergonomic Open-Ear Design: Instead of placing pieces deep into the ear canal (which can cause ear fatigue and isolation), the Liber uses a lightweight, open-ear headset design. This allows for comfortable all-day wear while keeping the user naturally aware of their immediate surroundings.
Dual-Mode Bluetooth 5.3: With a single click of the "Mode" button, users can instantly switch from Hearing Mode (amplifying the remote mic) to Bluetooth Mode for answering cellular phone calls or streaming music.
Straightforward Volume Control: Features 9 sequential levels of volume adjustment, allowing users to quickly and easily scale the total audio amplification up or down to suit their environment.
Fast-Charging Battery: A quick 1-hour charge via USB-C provides up to 10 hours of continuous operational runtime.

Edward Walker
Comfortable After a Few Days
They took a little getting used to at first,
especially adjusting the volume, but after a few days I got comfortable. Now I wear them regularly when I need them.

Robert J
Finally Following Conversations Again
I’ve been dealing with mild hearing loss for a few years now, especially in group conversations. I finally decided to try something more affordable before going the full medical route. These have been a very good solution for me. I can actually follow conversations again without guessing half of what’s being said.

Charles
A Noticeable Difference in Daily Life
These are my first hearing aids, so I don’t have much to compare to, but I can say they’ve made a noticeable difference. Conversations are clearer, and I feel less frustrated during the day.

Richard Evans
Easier TV Listening at Home
I use these mostly at home and when watching TV. They’ve reduced the need to turn the volume up so high. My family definitely appreciates that. Comfortable enough to wear for a few hours at a time.

Steven Harris
Hearing Softer Voices Again
The biggest difference for me is being able to hear softer voices again. Before, I was missing a lot unless people spoke loudly. These help bring that back in a very natural way.

Donna
Hearing My Granddaughter Clearly Again
I can finally hear my granddaughter clearly when she talks to me. That alone made this worth it. It’s a small change, but it means a lot to me.

Kevin White
Clearer Conversations Every Day
I mainly use these when watching TV and during conversations with my wife. The clarity is noticeably better. It’s not perfect, but it’s a big improvement compared to before.

Michael T
Better Than Expected
I wasn’t expecting too much at this price point, but I have to say I’m pleasantly surprised. The sound is clear enough for daily use, especially for TV and conversations. It struggles a bit in noisy places, but overall very usable.
