HOCO EQ4 Wireless Open-Ear Headphones with Air-Conduction Technology

Wireless open-ear headphones with air-conduction technology

Enjoy comfortable, wireless music listening with these modern, over-the-ear Bluetooth headphones! Thanks to the open-ear design, the earbuds don’t completely block your ear canal, so you can still hear sounds from your surroundings while using them. They’re the ideal choice for sports, walking, driving, working, or everyday use.

The device uses Bluetooth 5.3 technology, which ensures a stable connection, fast pairing, and low power consumption. The earbuds support the most important Bluetooth protocols, such as Headset, Hands-free, A2DP, and AVRCP modes, making them convenient for both phone calls and listening to music.

Air-conduction technology, comfortable open-ear design

The earbuds use air conduction technology. This means that sound is not transmitted through a rubber earbud inserted into the ear canal, but is instead delivered in a more open, comfortable way. As a result, it remains comfortable even during extended use, while still allowing you to hear important sounds from your surroundings.

The over-the-ear design provides a secure fit, so the earbuds stay comfortably in place even when you’re on the move.

Long battery life and a practical charging case

The earbuds feature a high-capacity battery. Each earbud has a 110 mAh battery, while the charging case has a 500 mAh battery. A single charge provides up to 12 hours of talk time or music playback at 80% volume, with a standby time of up to 300 hours.

The charging case can be charged via a Type-C connector, allowing for quick and convenient recharging. The charging case takes approximately 2 hours to fully charge, while the earbuds take about 1.5 hours.

Automatic Power-On and Pairing

Using the earbuds is extremely simple. When you take them out of the charging case, they automatically turn on and enter pairing mode. When you place them back in the case, they automatically turn off and begin charging. This ensures a convenient, fast, and energy-efficient user experience.

The device supports lead-follower earbud switching, voice assistant activation, track skipping, and playing and pausing music.
