SENTRY OSH are over-ear Bluetooth headphones with active noise cancellation, an adjustable ergonomic fit, and up to 22 hours of playback for everyday listening and travel.

These SENTRY OSH headphones combine -20dB Active Noise Cancellation, Bluetooth 5.3 connectivity, and a foldable, travel-friendly design to deliver a balanced feature set at an accessible price. They include on-ear controls, a built-in microphone for calls, USB-C charging, a 4-foot aux cable for wired use, and a protective carrying case. Whether you commute, work from home, or travel, these headphones are tuned to reduce distraction and extend listening time between charges.

How effective is the noise cancellation for commuting and office use?

The SENTRY OSH uses Active Noise Cancellation that reduces ambient sound by up to -20dB, lowering mid- and high-frequency distractions such as conversation and city noise. ANC performance is targeted to make voices and typical background hum less intrusive without introducing heavy processing artifacts.

• -20dB ANC for mid/high frequency reduction
• Passive noise isolation from over-ear cushions for low-frequency damping
• Can be used with ANC off to save battery or with wired aux for full signal

How long will the battery last and how quickly does it recharge?

SENTRY OSH provides up to 22 hours of continuous playback on a full charge from its 400mAh battery, suitable for long workdays or round-trip flights. Charging uses USB-C and takes about three hours to reach a full charge with the included cable.

• 22 hours typical wireless playback per full charge
• 400mAh battery capacity with approximately 3-hour full charge time
• USB-C cable included for faster, standardized charging

Can I control music and calls without reaching for my phone?

Yes — tactile on-ear buttons let you adjust volume, skip tracks, answer and end calls, and toggle ANC. A built-in microphone supports hands-free calling; Bluetooth 5.3 provides reliable connectivity up to about 30 feet from the paired device.

• On-ear controls for play/pause, track skip, and call management
• Integrated microphone for voice calls and virtual assistants
• Bluetooth 5.3 with ~30 feet range and no app required for pairing

Are these headphones portable and comfortable for long wear?

The headphones feature an ergonomic over-ear design, adjustable headband, and fold-flat hinges so they collapse into the included carrying case. Soft ear cushions reduce pressure for extended listening sessions and the bi-fold design keeps them compact in bags.

• Adjustable headband and soft over-ear cushions for comfort
• Bi-folding mechanism for compact storage in the carrying case
• Includes 4-foot aux cable for wired use when battery is depleted
