OhO Smart Glasses MP3 Bluetooth Sunglasses - Open Ear Audio

In this review of the OhO Smart Glasses, the bottom line is simple: these Bluetooth sunglasses are aimed at active users who want music and calls without isolating their ears. The single biggest reason to buy is the built-in open ear speaker system paired with Bluetooth 5.3, which lets wearers hear audio and surroundings simultaneously for safer outdoor use. The glasses feel like a wearable audio device first and sunglasses second, with transitional lenses for indoor reading and outdoor sun protection.

Key Features

• Bluetooth 5.3 chipset: Provides lower power consumption and stable wireless connections so the sunglasses can play audio for long periods.
• Up to 7 hours battery life: A single charge supports extended listening and hands-free calling during workouts or commutes.
• Open ear speaker system: Lets you listen to music and take calls while remaining aware of traffic and surroundings.
• Transitional polarized lenses: Offer impact resistance, 100% UV protection and change from clear indoors to light grey outdoors for versatile use.
• Voice assistant support: Hands-free access to Siri, Google Now or Cortana for calls, directions and quick voice control while on the move.
• Dual device pairing: Can connect to two phones at once so you can manage calls from either device without re-pairing.

Who It's For

These glasses suit runners, cyclists and commuters who need hands-free audio and situational awareness during outdoor activity. The open ear design means users who dislike earbuds or need to hear ambient noise will appreciate the tradeoff of less in-ear isolation for increased safety.

They are less suitable for listeners who demand deep bass or complete audio privacy, since open ear speakers will not deliver the sealed soundstage of in-ear or over-ear headphones. Also, people who need prescription lenses should consider models that accept prescription inserts or dedicated audio frames.

Pros & Cons

Pros

• Open ear speakers provide safe situational awareness while listening to music or taking calls.
• Bluetooth 5.3 chipset and USB-C charging support up to about seven hours of continuous playback.
• Transitional polarized lenses block 100% UV and switch from clear to light grey for indoor/outdoor use.
• Voice assistant and dual-device pairing make hands-free control and multi-phone setups convenient.

Cons

• Open ear audio sacrifices deep bass and full isolation compared with in-ear or over-ear options.
• Not a bone conduction design, so audio leaks may be noticeable in very quiet environments.
