Design and Comfort

The YOSINT GT27 earbuds have a lightweight plastic build with an open ear design that rests the speaker module gently on the top of the ear rather than sealing in the ear canal. The open ear design helps reduce ear fatigue during prolonged listening sessions compared to in-ear models.

Each earbud weighs only 4.5g making them comfortable for long term wear. The ear hooks are adjustable and do a good job of keeping the earbuds stable during activity. The IPX7 waterproof rating means they can withstand sweat and splashing water.

True Open Ear Headphones

The YOSINT GT27 headphones feature a completely open design, allowing the earbuds to be gently placed on the top of the ear. Unlike traditional wireless earbuds, the open-ear design eliminates the need for inserting the earbuds into the ear canal. This unique feature ensures that your ears remain comfortable even during extended listening sessions and prevents any soreness or damage.

Traditional Headphones vs. Bone Conduction Technology

Traditional headphones, including in-ear and over-ear designs, rely on sound waves traveling through the air and entering the ear canal to produce sound. In contrast, bone conduction headphones, like the YOSINT GT27, use vibrations that bypass the outer and middle ear, directly stimulating the inner ear’s cochlea. This unique approach allows users to hear sound while keeping their ear canals open, making them ideal for situations where environmental awareness is crucial, such as outdoor activities or certain work environments.

Air Bone Conduction Technology

Unlike conventional bone conduction headphones that use vibration sounding methods, the YOSINT GT27 Open Ear Wireless Headphones adopts air conduction technology. This principle avoids uncomfortable vibrations and ensures that your ears feel comfortable, even after long hours of use.

Bluetooth 5.3 & Latest Bluetooth Chip

The YOSINT GT27 Open Ear Wireless Headphones utilizes the most advanced Bluetooth 5.3 technology, providing a stable and efficient wireless connection. With the built-in Bluetooth chip, you can enjoy clear audio without any disruptions. The headphones also feature noise and echo cancellation, ensuring crystal-clear phone calls and immersive music playback. The audio processor with DSP enhances the bass sound, delivering a truly captivating sound experience.

One-Step Pairing & Touch Control

Pairing the YOSINT GT27 Open Ear Wireless Headphones with your device is effortless. Simply open the charging case, and the headphones will automatically connect to the last paired device. The touch control functionality allows you to answer or hang up calls, play/pause music, skip tracks, adjust volume, and access other functions with a simple touch on the earbuds. The intuitive controls make it convenient to manage your audio playback without reaching for your device.

Hi-Fi Stereo Sound

Equipped with graphene-coated drivers, the YOSINT GT27 Open Ear Wireless Headphones provides superior sound quality. The headphones deliver crystal-clear audio, deep bass, and a finely tuned sound signature that immerses you in your favorite music.

Battery Life

Battery life is a highlight with up to 8 hours of continuous playback per charge. The compact charging case provides an extra 4 full charges for up to 32 hours total. The case displays the exact percentage of remaining battery to avoid unexpectedly running out of power. A quick 10-minute charge can provide up to 2 hours of playtime.

Water Resistance

The IPX5 water resistance rating means the YOSINT GT27 headphones can withstand sweat, rain, and splashes. They are suitable for using during workouts and running without damage from moisture. However, they should not be submerged underwater. The water protection combined with the stable fit makes them ideal for active lifestyles.

Use Cases

The open design of the YOSINT GT27 Open Ear Wireless Headphones makes them ideal for use during activities like exercising, walking, hiking, biking, and running where situational awareness is important. Users praise them for allowing them to hear traffic and nature while still enjoying their music.

They work well for phone calls with their built-in mics and wireless connectivity. The IPX5 water resistance also enables using them during workouts involving sweat without damage.

While the open earbuds do leak sound, they can still be suitable for quiet office use if volume is kept moderate. However, the lack of noise cancellation limits their effectiveness in very noisy environments like commuting.

User Feedback and Value Analysis

With over 1,500 Amazon reviews, the YOSINT GT27 headphones have received largely positive feedback from buyers. The average rating is 4 out of 5 stars. Many reviewers praise the comfortable fit and open ear design that prevents ear fatigue during long listening sessions.

Sound quality and battery life also receive positive marks, especially considering the budget-friendly price point. Reviewers mention the GT27 provides good value for those looking for an affordable open ear headset.

Overall though, reviews indicate the YOSINT GT27 Open Ear Wireless Headphones perform well for casual listening and active use.

Frequently Asked Questions

Q: What is the difference between air conduction and bone conduction headphones?

A: Both air conduction and bone conduction headphones are designed to leave your ear canal open for situational awareness. However, they transmit sound vibrations differently:

  • Air Conduction: Headphones like the YOSINT GT27 rest just outside your ears and transmit sound vibrations through the air. This is still audible to those around you.

  • Bone Conduction: These headphones send vibrations directly through your cheekbones to your inner ear. Sound leakage is minimized, making them better for crowded environments where you need to keep your audio private.

Q: How is the sound quality of the YOSINT GT27 Open Ear Wireless Headphones?

A: The YOSINT GT27 Open Ear Wireless Headphones feature Hi-Fi stereo sound with graphene-coated drivers, promising clear audio and a good amount of bass. However, open-ear designs generally don’t offer the same depth and richness as in-ear headphones, especially in noisy environments.

Q: Are these headphones good for workouts and running?

A: User reviews suggest that the YOSINT GT27 Open Ear Wireless Headphones stay in place securely during physical activity. Their open-ear design is also beneficial for runners and cyclists who need to stay aware of their surroundings. Keep in mind that sweat might affect connectivity, as some users have reported this issue.

Q: How do I switch the voice prompts between Chinese and English?

A: According to the instructions, double-tap either earpiece when the headphones are not connected to your phone to switch languages.

Q: Can the YOSINT GT27 Open Ear Wireless Headphones be paired with a smartwatch?

A: If your smartwatch supports Bluetooth pairing with audio devices, it’s likely to be compatible with the YOSINT GT27 headphones.


  • Charging and Maintenance: Use the included charging cable with the case for optimal charging. Regularly clean the contact points on both the earbuds and inside the case with a soft cloth to ensure proper charging.
  • Connectivity: Keep your device within Bluetooth range to avoid signal interruptions. If you experience connectivity issues, try re-pairing the headphones to your device.
