If you want sunglasses that double as open-ear headphones for music, calls and voice assistants, choose vtyvty Audio Sunglasses; if you need a protective locking shell for a Beats Powerbeats Fit charging case, choose Generic Secure Lock. These two products do not compete for the same job — one is wearable audio, the other is a case accessory. The choice comes down to whether you are buying something to wear or something to protect what you already own.
• vtyvty Audio Sunglasses — biggest strength: Bluetooth 5.0+ audio, a built-in mic, voice assistant access and UV400 lens protection in a single ~35g frame, with up to 8 hours of playback.
• vtyvty Audio Sunglasses — biggest trade-off: The open-ear design deliberately lets ambient sound in, so it will never isolate you the way in-ear buds do, and there is no display or GPS.
• Generic Secure Lock — biggest strength: A front locking switch that helps keep the cover closed, plus soft TPU protection, a carabiner and a cleaning pen in one kit.
• Generic Secure Lock — biggest trade-off: It is a cover only — it adds no audio, no battery and no function to your earbuds beyond physical protection.
• Choose vtyvty Audio Sunglasses if you want to listen, talk and stay aware outdoors without earbuds.
• Choose Generic Secure Lock if you already own Beats Powerbeats Fit earbuds and want to keep the charging case safe and shut.
The vtyvty Audio Sunglasses (model C11) are a pair of rectangular black sunglasses with speakers built into the frame. The lens carries UV400 protection, which the spec sheet describes as blocking 99% of UVA/UVB rays. Where the audio side is concerned, you get Bluetooth 5.0+ connectivity to a phone or tablet, a high-quality microphone for hands-free calls, and one-tap access to Siri or Google Assistant. Controls are physical buttons rather than touch surfaces — a deliberate choice, since it means volume, playback and call handling happen precisely instead of by accidental tap.
What makes this category interesting is the open-ear approach. Because the speakers sit outside your ear canal, you keep hearing traffic, footsteps and conversation around you. That is the whole point for commuting, driving, cycling, running or hiking, where blocking your ears is a genuine safety trade-off. Battery life is listed at up to 8 hours of continuous playback (it varies with volume), with roughly an hour to charge over USB-C. At about 35g, the frame is built to be worn all day, and the package includes the sunglasses, a Type-C cable, a protective pouch and a manual.
Generic Secure Lock: Who It's For
The Generic Secure Lock is a clear orange protective cover made specifically for the Beats Powerbeats Fit charging case. It is a case accessory, not a device. The headline feature is the front locking switch, which helps hold the cover closed and reduces the chance of the case popping open in a bag, pocket or carry-on. If you have ever pulled a charging case out of a backpack and found the lid hanging open, that switch is the reason this product exists.
The shell is soft TPU, chosen to absorb everyday scratches, bumps, dust and minor drops while staying flexible enough to fit and remove easily. Cutouts are positioned so you can charge without taking the cover off — a small detail that matters daily. For carrying, a carabiner clip lets you hang it from a backpack, handbag, belt loop, keyring or travel bag. There is also a multifunction cleaning pen with a fine tip and a soft brush for clearing dust out of the small gaps and surfaces where earbud cases collect grime. The kit includes the protective case, the carabiner and the cleaning pen.
Who should buy it? Powerbeats Fit owners who carry their case loose in a bag, clip gear to a backpack, or want the case to stay shut and stay clean. It suits commuters, gym-goers and travellers especially. The clear orange finish is also a practical choice if you want to keep the case's look visible rather than hiding it behind an opaque shell. Who should skip it? Anyone who does not own Beats Powerbeats Fit earbuds — compatibility is specific — and anyone hoping this does something functional. It adds protection and a carrying method, nothing more. It has no electronics, no battery and no audio role. And remember: it protects the case, not the earbuds themselves.
Side-by-Side: Which Should You Choose?
• Best for listening on the move → vtyvty Audio Sunglasses. Bluetooth 5.0+ audio, an open-ear design and up to 8 hours of playback make it the only one of the two that plays anything.
• Best for eye protection → vtyvty Audio Sunglasses. UV400 coverage blocking 99% of UVA/UVB is a core spec; the lock offers no UV function.
• Best for protecting your earbuds case → Generic Secure Lock. Soft TPU plus the front locking switch addresses scratches, dust, bumps and accidental opening.
• Best for carrying gear hands-free → Generic Secure Lock. The carabiner clips to bags, belt loops and keychains; the sunglasses are worn, not clipped.
• Best for keeping things clean → Generic Secure Lock. The included cleaning pen with a fine tip and soft brush handles dust in tight gaps.
• Best for all-day wear comfort → vtyvty Audio Sunglasses. At roughly 35g with a lightweight frame, it is designed to sit on your face for hours.
• Best for charging convenience → a tie, in different ways. The sunglasses use universal USB-C, while the lock's precise cutouts let you charge the case without removing the cover.
In my opinion, most people searching these two names together are actually deciding between "audio I can wear" and "protection for audio I already own" — and those are different purchases. If I had to pick one as the more broadly useful buy, I would take the vtyvty Audio Sunglasses. It does a job on its own: music, calls, voice assistant, UV400 lenses and up to 8 hours of playback in something you simply put on. The Generic Secure Lock is genuinely good at what it does, but it only matters if you already own Beats Powerbeats Fit earbuds and want the case to stay shut and clean. Buy the lock as an accessory; buy the sunglasses as the product.
No. The vtyvty pair is a wearable audio device with Bluetooth, a mic, UV400 lenses and up to 8 hours of playback. The Generic Secure Lock is a TPU protective cover for a Beats Powerbeats Fit charging case. One is worn; the other protects what you already have.
Do the vtyvty Audio Sunglasses block out noise like earbuds?
The spec sheet lists it as specifically designed for the Beats Powerbeats Fit charging case, so treat compatibility as that model only. It includes a carabiner clip and a cleaning pen, and the front locking switch helps keep the cover closed during travel.
Decide by the job: choose the vtyvty Audio Sunglasses if you want to listen, call and shade your eyes; choose the Generic Secure Lock if you need to protect a Powerbeats Fit case. Since neither data set includes pricing, check the current price on Amazon before you buy.
