Botesty Sound lris 3.5mm Wired Headphones

The Botesty Sound lris is a wired over-ear headset with a 3.5mm connector and a 4.9ft tangle-free nylon cord. A built-in microphone on the cable supports hands-free calls and online learning. The foldable design aids storage and transport for daily use.

Suits 3.5mm devices only; no USB or Lightning

These headphones connect solely via a 3.5mm jack, so they suit smartphones, tablets and laptops that retain that port. Volume is controlled on the device, not the headset. The microphone is not supported on desktops or certain laptops, and some adapters will not pass the mic signal.

40mm drivers with 40 ohm impedance

The 40mm driver units present a 40 ohm input impedance and deliver a 20Hz frequency response with 110dB sensitivity and signal-to-noise ratio. Passive noise cancellation comes from the over-ear cups. The microphone shares the same 40 ohm impedance and 110dB ratings.

Questions about this item

Does the 3.5 mm plug require a separate headphone and microphone port or a single combined jack?

The 3.5 mm connector is a single plug; microphone function depends on the device supporting a combined headset jack — desktops with separate ports and some laptops will not enable the mic.

Will the 40 mm drivers and 110 dB sensitivity work properly with an older smartphone that has a 3.5 mm jack?

Yes — the 40 mm drivers, 40 ohm impedance and 110 dB sensitivity are designed for standard 3.5 mm outputs found on older smartphones and tablets.

How can I confirm the headset is delivering the rated 20 Hz to 20 kHz response after plugging it in?

Play a frequency sweep test track; you should hear continuous output down to 20 Hz and up to the upper limit without distortion at normal listening levels.
