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.\u003c\/p\u003e\n\u003cp\u003eTouch 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.\u003c\/p\u003e\n\u003cp\u003eThe 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).\u003c\/p\u003e\n\n\u003ch5\u003eWhy You'll Like It\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eOpen-ear audio design\u003c\/strong\u003e\u003cbr\u003eDual speakers deliver sound without blocking your ears, so you stay aware of traffic and surroundings while still hearing your music or calls.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTAC polarized lenses\u003c\/strong\u003e\u003cbr\u003eCuts glare and reflected light from roads, water, and glass for clearer vision in bright conditions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTouch controls, no separate remote\u003c\/strong\u003e\u003cbr\u003eAnswer calls, skip tracks, and trigger your voice assistant with taps on the temple, keeping your hands on the bars.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMagnetic fast charging\u003c\/strong\u003e\u003cbr\u003eA magnetic cable clips straight on for a full charge in roughly 1.5–2 hours, no fiddly port to align.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLightweight, all-day build\u003c\/strong\u003e\u003cbr\u003eAt about 43g with adjustable nose pads, the frame stays comfortable over long rides rather than pinching or sliding.\u003c\/p\u003e\n\n\u003ch5\u003eWho Is It For?\u003c\/h5\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\n\u003ch5\u003eGood to Know\u003c\/h5\u003e\n\u003cp\u003eUse 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.\u003c\/p\u003e\n\n\u003ch5\u003eTechnical Specifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame Material\u003c\/strong\u003e: TR Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLens Type\u003c\/strong\u003e: TAC Polarized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBluetooth Version\u003c\/strong\u003e: 5.2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery Capacity\u003c\/strong\u003e: 120mAh\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMusic Playback\u003c\/strong\u003e: Approx. 5.5–6 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTalk Time\u003c\/strong\u003e: Approx. 5 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandby Time\u003c\/strong\u003e: Approx. 60 hours\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCharging Time\u003c\/strong\u003e: Approx. 1.5–2 hours (magnetic charging)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: Approx. 43g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIn The Box\u003c\/strong\u003e: Glasses, magnetic charging cable, protective case\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eAdditional Information\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: China\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImported By\u003c\/strong\u003e: Do Good Co, 223, Laxmi Plaza, SAB TV Road, Suresh Nagar, Andheri West, Mumbai, Maharashtra -400053, India.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNet Quantity\u003c\/strong\u003e: 1N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustomer Care Address\u003c\/strong\u003e: 291, 10 Main, 5 Block, Jayanagar, Bangalore - 560041.
