Spider X23 Open-Ear Headphones

The Spider X23 uses bone conduction technology to transmit audio through the cheekbones while leaving the ear canals open. Weighing 23 grams with a flexible memory-titanium frame, they suit runners, cyclists and outdoor workers who need situational awareness during long sessions.

Adjustable Strap and Earplugs Included

An adjustable strap lets wearers secure the frame for different head sizes. Silicone earplugs are also supplied; inserting them blocks ambient noise when the user wants isolation instead of awareness, effectively giving two listening modes from one device.

Bluetooth 6.0 Wireless Limits

Bluetooth 6.0 provides a 33-foot range and 60-millisecond latency for stable streaming. The 10-meter practical range means walls or interference can reduce coverage, and the 10-hour battery requires a two-hour recharge after a full day of use.

Questions about this item

Will the 23 g titanium frame or the adjustable strap need replacing after daily runs?

The memory-titanium frame is built for long-term flexibility and the adjustable strap is designed to fit different head sizes without wear, so neither component typically requires replacement under normal use.

What stops the 10-hour battery from lasting a full workday of calls and music?

Continuous streaming at high volume or frequent microphone use will draw more current and can reduce the 10-hour operating time before a 2-hour recharge is needed.

How warm do the 13 mm drivers get and does the open-ear design stay quiet after hours of playback?

Bone conduction drivers run cool against the cheekbones, and the open-ear cavity keeps sound leakage low without generating noticeable heat during all-day wear.
