good headphones for metal detecting
Experienced diggers and treasure hunters pay close attention to the compatibility of headphones with metal detectors. Many modern manufacturers produce standardized and fully compatible accessories, but they are quite expensive.
There are important criteria for choosing wireless options for a metal detector. They make it easy and simple to find a suitable model of auxiliary audio equipment for use with search devices.
Response speed. Ideally, it should be zero. With Bluetooth, latency occurs more frequently, and this difference can be critical.
Operating frequency range. Standard indicators range from 20 to 20,000 Hz. Such headphones will transmit all frequencies audible to the human ear.
Water resistance. The higher it is, the more reliable the devices will perform in extreme conditions. The best models in a sealed case can even withstand direct exposure to heavy rain or hail.
Sensitivity. For working with a metal detector, it should be at least 90 dB.
Continuous operating time. The longer the headphones can function without recharging, the better.
Noise isolation level. It is better to choose models in which footsteps or voices can still be heard. Complete noise isolation would be excessive.
