Joysico YS4 Open Ear Headphones 14mm 3.5mm 26g

Open-ear headphones for all-day wear

Joysico YS4 open-ear headphones rest on the outside of the ear, leaving the canal open. The 14 mm drivers and flexible ear hooks provide a secure fit without clamping pressure. Weighing 26 grams, they suit users who find in-ear buds uncomfortable or who need situational awareness during outdoor activities. A 3.5 mm plug connects directly to compatible devices.

3.5 mm wired connection limits device compatibility

The headphones use a 3.5 mm analogue connector with no wireless capability. They work natively with laptops, consoles and older phones that retain a 3.5 mm jack. Newer smartphones, tablets and ultrabooks that only offer USB-C or Lightning ports require a separate adapter, which is not included. The wired design also means the cable can snag during vigorous movement.

14 mm drivers tuned for clarity, not bass

The 14 millimetre dynamic drivers deliver 95 dB/mW sensitivity at 16 ohms impedance. The supplier states the sound signature is balanced and clear but explicitly not suited for heavy bass enthusiasts. Microphone sensitivity and signal-to-noise ratio are both rated at 95. Buyers prioritising deep low-end response should look elsewhere.
