About this item

  • 【OWS True Bone Conduction 】Unlike traditional air conduction that blocks your ear canal, our OWS true bone conduction technology transmits sound through temporal bone vibrations, keeping your ears completely open. This not only eliminates ear canal pain but also allows you to stay aware of your surroundings during workouts or commutes, ensuring auditory safety. The exclusive directional sound transmission structure effectively contains sound leakage, keeping your listening private and secure.
  • 【0.8g Ultra-Lightweight】Each earbud weighs just 0.8g and is crafted with a memory titanium alloy ear hook and skin-friendly medical-grade silicone for a light, comfortable fit. The ergonomic ear hook design ensures a secure and stable fit for various ear shapes, staying firmly in place even during intense activities like running and workouts—perfect for all kinds of sports.
  • 【IPX5 Sweat-Resistant】Featuring a water-resistant coating and sealed construction, these earbuds stand up to heavy sweating and accidental rain. However, please note: they are not designed for underwater use. Avoid direct rinsing, submerging, or wearing them in the shower to maintain the product's performance and longevity.
  • 【Bluetooth 5.4】This open ear earbud is equipped with advanced Bluetooth 5.4 technology, ensuring that you can easily connect to your mobile phone, tablet or other devices. This Bluetooth bone conduction earbud offers faster and more stable performance, with stable transmission within 10 meters. You don't need to worry about signal loss or delay issues. The smooth connection allows you to enjoy music and calls seamlessly
  • 【Intuitive Touch Controls & Portability】Enjoy simple and convenient control with responsive touch-sensitive earbuds. Play/pause, skip tracks, and answer calls with a quick tap. The built-in microphone ensures clear communication whether you are on a call or using a voice assistant. Its portable design makes the headphone easy to carry, suitable for a variety of occasions, whether sports or daily travel is very convenient

Stylish and Secure for Gym Workouts

AndyLeuDecember 21, 2025✓ Verified purchase

The design is sleek and stylish. These are perfect for the gym because they stay securely in place even during intense workouts. However, I’d suggest keeping the volume at a moderate level; at high volumes, the vibration becomes noticeable and can be a bit uncomfortable for the ears Read more

Ok for sleep noise but the battery life isn't great

Jason PJanuary 9, 2026✓ Verified purchase

Bought these for sleep masking noise. They work pretty well at 50%+ volume. They're fairly comfortable even side sleeping. Though the battery life is consistently about 4-5 hrs ... nowhere near long enough to make it through a good sleep. Sound quality isn't anything like even a low end pair of headphones or earbuds. Case is nice, magnetically holds the earbuds in. Charging lights are ridiculously bright, annoyingly so I think. Light weight. I had to pair each earbud separately... not sure if that's expected but its also a negative in my opinion. Read more

Hurt my ears

They hurt my ears. They just didn’t fit right. It may just be me, but I could not use them. Read more

Good sound and comfortable fit

ConstanceOctober 23, 2025

I’ve been using these headphones for a while now, and they’ve worked really well for my daily walks and casual use. The sound is clear and balanced, not too heavy on bass, but pleasant for music and podcasts. I really like the open ear design, it lets me stay aware of what’s going on around me, which feels safer when I’m outside. They’re lightweight and comfortable to wear for long periods without causing pressure on my ears. The battery lasts a long time, and the waterproof feature adds convenience if I’m sweating or caught in light rain. Connecting to my phone is quick and easy, and the controls are simple to use. The fit could be a little more adjustable, but it still stays secure enough during movement. These are solid, comfortable headphones that perform well for everyday listening and light workouts.

Home office

derekOctober 29, 2025

I often wear these headphones for video meetings while working from home. Open-back headphones are not completely soundproof, so I can still hear my kids when they call me. The sound quality is clean, the voice is clear, and it is not dull when worn for a long time. The lightweight body made me almost forget it existed. The battery life is strong, so you don’t have to worry about running out of power even during multiple meetings a day. Read more
