Esperanza EH147K In-Ear Headset with Microphone, Wired, Black

For clear calls and rich music on the go, the Esperanza EH147K in-ear headset pairs a built-in microphone with a comfortable silicone-tip design. Unlike basic earbuds, it includes an in-line control for volume and call management, while the 10 mm drivers deliver balanced sound from 20 Hz to 20 kHz. The 1.2 m cable with 3.5 mm TRRS jack works with smartphones, tablets, and laptops that have a standard audio port.

Highlights

• Built-in microphone with -58 dB sensitivity for hands-free calls
• In-line control for volume adjustment and call answer/end
• 10 mm dynamic drivers with 32 Ω impedance and 105 dB sensitivity
• Closed acoustic design reduces ambient noise
• Soft silicone ear tips in multiple sizes for a secure fit
• Universal 3.5 mm TRRS connector for wide compatibility

In daily use

Plug the EH147K into your phone, tablet, or laptop and you are ready for music, podcasts, or conference calls. The in-line control lets you adjust volume without reaching for your device, and the microphone picks up your voice clearly even in moderately noisy environments. The closed design helps isolate sound, while the lightweight build and silicone tips keep you comfortable during long listening sessions.
