【True Open Ear Headphones】 The Monster AC210 features a completely open-back design for ultimate comfort, allowing sound to embrace the ears.
【360° Excellent Sound Quality】 The Monster AC210 Bluetooth headset uses dual powerful 12mm dynamic driver units and modified PI composite beryllium diaphragms, as well as the 30mW thrust of the DAC sound card to make the sound more three-dimensional and concrete.
【Resists Hearing Loss】This open-back earplug avoids the most common health concerns of traditional earplugs because it never actually enters the ear. No pinching of the auricle, no pain, and no damage to hearing.
【Extra long battery life】Up to 6 hours of listening time (up to 30 hours when combined with the charging case)
These headphones also make a great Christmas or birthday gift, or a perfect gift for adults to exchange. If you have any questions, please feel free to contact us; our professional team will be happy to assist you.
