Polarized cycling sunglasses for riders who want their music or calls without plugging their ears, built around open-ear speakers that leave you aware of traffic around you.
Overview
The SP251 pairs TAC polarized lenses with a built-in Bluetooth 5.2 audio system, running two Hi-Fi speakers positioned at the front and rear of each temple. The open-ear design lets sound reach you without sealing off your ears the way in-ear buds do, so you can still hear traffic, other riders, and your own breathing while riding.
Touch controls on the temple handle calls, track skipping, and voice assistant access with simple tap and press gestures, so there's no separate remote or phone fumbling mid-ride. A 120mAh battery delivers roughly 5.5–6 hours of music or 5 hours of talk time, recharging in about 1.5–2 hours over a magnetic charging cable that clips on without needing to find a port.
The lightweight TR-plastic frame comes in at around 43g, with adjustable nose pads and curved temples for a secure, comfortable fit, and the frame includes a mount for a corrective-lens insert if you need one (insert sold separately).
Why You'll Like It
Open-ear audio design
Dual speakers deliver sound without blocking your ears, so you stay aware of traffic and surroundings while still hearing your music or calls.
TAC polarized lenses
Cuts glare and reflected light from roads, water, and glass for clearer vision in bright conditions.
Touch controls, no separate remote
Answer calls, skip tracks, and trigger your voice assistant with taps on the temple, keeping your hands on the bars.
Magnetic fast charging
A magnetic cable clips straight on for a full charge in roughly 1.5–2 hours, no fiddly port to align.
Lightweight, all-day build
At about 43g with adjustable nose pads, the frame stays comfortable over long rides rather than pinching or sliding.
Who Is It For?
This suits riders who want music or hands-free calls on solo rides without losing awareness of the road — commuters navigating traffic, or anyone doing long training rides who'd rather not deal with wired earphones catching on a jersey collar. It's equally useful for anyone who already wears corrective lenses, since the frame accepts a prescription insert.
Good to Know
Use the touch panel gestures to manage calls and tracks on the move — double-tap to play/pause or answer, triple-tap to skip, and a long press to power on or off. Keep the magnetic charging cable handy since a full charge takes under two hours and tops up quickly between rides.
