Design

The Kaibo Flex has an open-ear design with the transducer resting on your cheekbone to send audio using bone conduction technology. This allows you to listen to music or take calls while still hearing ambient noise around you, unlike regular earbuds that block outside sound.

The headset itself is lightweight and flexible to fit comfortably on your face. The materials feel durable with rubberized finish and aluminum alloy frame. It comes in black, blue, or red color options.

Audio Quality

With bone conduction headphones, sound quality is a bit different than traditional headphones. The Kaibo Flex produces clearer mids and highs than competing bone conduction models, though the bass response is lighter. Overall, the audio comes through crisp and detailed, albeit not as robust as over-ear headphones.

The open-ear design does allow in ambient noise which can distract from your audio. But this compromise allows you to remain aware of your surroundings, which is the main draw of bone conduction headphones.

Features

  • Touch controls: Tap to play/pause music or answer calls
  • Bluetooth 5.2 provides stable wireless connection
  • IP55 sweat and water resistance rating
  • 8 hours battery life, up to 28 hours with charging case
  • Quick charge gives 1 hour of playtime from 5 minutes of charging
  • Wireless charging dock for convenience

Use Cases

The Kaibo Flex bone conduction headset is ideal for activities like:

  • Running or biking outdoors - hear traffic and people around you
  • Working out at the gym - be aware of people around you
  • Walking the dog - listen to podcasts but still hear the environment
  • Driving - hear navigation prompts without blocking your ears

The open-ear design makes them great for situational awareness compared to regular earbuds. Though audio quality compromises make them less ideal for dedicated music listening sessions.

User Feedback Analysis

The Kaibo Flex bone conduction headphones have received mixed yet largely positive reviews from customers.

On the upside, many users praise the innovative open-ear design that allows you to seamlessly blend audio and external ambient noises. This enables situational awareness during activities like running, biking, and walking the dog, unlike traditional headphones that block outside sounds. Users mention a feeling of safety being able to hear their surroundings while listening to music.

Comfort is another common positive, with the lightweight flexible headset fitting securely on most head shapes. Those with smaller heads do note the headset can feel loose at times. But overall, customers find the Kaibo Flex comfortable for extended wear.

In terms of sound quality, reviews indicate clear and detailed mids and highs coming through the bone conduction transducer. However, bass response is noticeably lighter given the open-ear design. Many customers accept this sound trade-off for the ability to hear ambient noises. But for serious music listening, they tend to still prefer traditional headphones.

On the downside, some users report connectivity dropouts and intermittent audio cutouts. Finding the optimal position on the cheekbone for best sound quality also requires some trial and error. At higher volumes, sound leakage can occur. Noise cancellation is mediocre for filtering background sounds during calls.
