The Sentry ProSeries Deluxe Folding Headphones are robust, convenient and functional. A great combination for travel, work and leisure. The wireless option (power and connectivity) is ideal. The black and silver is understated and sleek. They’ve been opened and they’ve sat around for a while. But they’ve never needed as he likes his wired set for home and his ear-buds for his phone when out / travelling.
