Editorial note
The 4smarts Harmony headphones stand out for their immersive audio experience, thanks to a frequency range of 20 to 20,000 Hz and a sensitivity of 96 dB, allowing for full enjoyment of music and podcasts. Their in-ear design ensures prolonged comfort, making these headphones ideal for home use or on the go. Additionally, the Plug and Play functionality simplifies installation, enabling quick connection to various devices without hassle. However, some drawbacks deserve to be highlighted.
