The product had a lifespan of only a few months, as now, after a full charge, it discharges within ten minutes, resulting in the high-intensity sound notification "battery low" interrupting your sleep.

Good construction quality as a fabric, good sound quality, fits the forehead very well and is comfortable, good battery life but the side where the controls and headphones are, if you sleep on your side, it kills you with pain.

Excellent for its price, I didn't expect it to work so well. Easy connection via Bluetooth with the press of a button, very good sound. Perfect for listening to music during sleep or for meditation. One negative aspect is the thick fabric of the mask, it would be perfect if it was thinner. 5 stars for the price-quality ratio.
