Hoco EA4 Cloud Open True Wireless Earbuds
Description
The Hoco EA4 Cloud Open are True Wireless Stereo (TWS) earbuds featuring an Open-Wear Stereo (OWS) design. Unlike traditional earbuds that seal the ear canal, the EA4 rests near the ear, using air conduction to deliver sound. This ensures the user maintains full awareness of their surroundings (situational awareness) while enjoying music or calls, making them ideal for outdoor sports, commuting, and notably, for comfortable use during sleep. They feature a clean, ergonomic design and leverage the latest Bluetooth standard for stable connectivity.Order from T-Tech or visit our shop at Shop- (New)06, 1st Floor, Shah Amanat City Corporation Super Market, Chittagong, Bangladesh.

FAQs
| Question | Answer |
| Do the Hoco EA4 have Active Noise Cancellation (ANC)? | No. As open-ear earbuds, they are designed to let ambient noise in for safety/awareness. They do not feature ANC. |
| Are they bone conduction or air conduction? | They are Air Conduction headphones, meaning they transmit sound through the air directly to the ear, but do not vibrate the cheekbones like bone conduction models. |
| Are they good for running/workouts? | Yes. The open-ear design enhances safety by allowing you to hear traffic, and the IPX5 rating makes them highly resistant to sweat and water. |
| What is the call quality like? | They feature a built-in microphone and are generally reliable for clear voice transmission, but they do not typically include advanced AI-based ENC (Environmental Noise Cancellation) found in higher-end models. |
| Can I summon my voice assistant? | Yes. They support summoning your device’s voice assistant, such as Siri, via the touch controls. |
