VR goggles Esperanza EMV300 — 3D compatible, adjustable focus, lenses Ø40 mm, phone size 3.5–6", spacing 55–72 mm

These head-mounted VR goggles let you watch 3D films and play VR games on Android or iOS smartphones with screen sizes from 3.5" to 6". The headset uses 40 mm aspherical lenses and offers adjustable lens distance and interpupillary spacing to reduce distortion and provide a clearer, more natural 3D image. The casing holds phones with widths from 60 mm to 80 mm and heights up to 160 mm, and includes a sliding front lid to allow use of the phone camera for augmented reality applications. The face pad is made of synthetic leather filled with elastic foam for a comfortable fit, and adjustable elastic straps keep the headset firmly on the head. Ventilation openings and side slots provide access for headphones and a charging cable.

Advantages

Aspherical 40 mm lenses reduce visual distortion and improve perceived depth, while adjustable lens distance (up to 10 mm) and adjustable interpupillary spacing (55–72 mm) allow personal tuning for clearer viewing. The sliding front lid enables camera use without removing the phone from the case. Synthetic-leather padding with elastic foam increases comfort and allows wearing with spectacles, and elastic straps ensure a secure fit.
