Isymphony Series 3 nrg3.0gbk Wooden In-Ear Headphones 3.5mm

Handcrafted Bubinga wood in-ear headphones

The Isymphony Series 3 FBA_nrg3.0gbk uses real Bubinga wood housings with 8mm dynamic drivers to produce deep bass and crisp tones. A 3.5mm plug connects directly to computers, laptops and phones without any charging requirement. Active noise cancellation helps reduce ambient sound during commutes or study sessions. The set includes 12 ear tips, a waterproof travel case, cord clip and carabiner for portability.

Plug-and-play with tangle-free cord

Insert the 3.5mm jack into any standard aux port and audio plays immediately; no drivers or power are needed. The tangle-free cable resists knots, while an inline remote provides volume control and call handling. A built-in microphone with approximately 3K ohm impedance supports hands-free calls. If the jack does not seat fully, sound may cut in one ear; ensure the connector is pushed in completely.

32 ohm input impedance matches portable sources

The 32 ohm rating allows the headphones to reach adequate volume from phone, laptop or tablet outputs without an external amplifier. Lower-impedance sources drive them cleanly, while higher-output devices will not cause distortion. Buyers who need wireless freedom or a USB-C digital connection should look elsewhere, as this model is purely analog and wired.
