SENTRY Over-Ear Bluetooth Headphones ANC 22-Hour

SENTRY OSH are wireless over-ear headphones with active noise cancellation up to -20dB, 22 hours of battery life, on-ear controls, built-in microphone, and a compact carrying case.

These SENTRY OSH headphones blend focused sound isolation, simple Bluetooth V5.3 pairing and a travel-friendly design to deliver everyday listening without fuss. They target commuters, remote workers, and travelers who want strong mid-to-high frequency noise reduction, straightforward controls, and long playback between charges. No companion app is required — pairing and basic functions are managed with on-ear buttons and standard Bluetooth protocols.

How effective is the active noise cancellation for commuting and flights?

The SENTRY OSH uses an active noise cancellation system tuned to reduce up to -20dB of ambient sound, especially mid and high frequencies such as chatter and cabin noise. This level of ANC greatly lowers distractions in crowded environments while preserving the clarity of your music or calls.

• ANC performance: up to -20dB reduction in mid/high frequencies
• Passive isolation: snug over-ear cups block additional background noise
• Designed to keep vocals and instruments clear while reducing ambient hum

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

A single charge provides up to 22 hours of continuous use from the built-in 400mAh battery, suitable for a full day of commuting or multiple long flights. When the battery is depleted, a full recharge takes about three hours using the included USB-C cable, which is a convenient modern standard for travel adapters and power banks.

• Battery capacity: 400mAh for extended playback
• Playback time: up to 22 hours per full charge
• Charging: USB-C cable included, full charge in ~3 hours

How easy are they to use with phones, tablets, and laptops?

Pairing is fast and app-free thanks to Bluetooth V5.3, providing stable connections up to about 30 feet. On-ear controls let you adjust volume, skip tracks and answer calls without unlocking your device, while a built-in microphone handles hands-free conversations.

• Bluetooth V5.3 for reliable wireless range (~30 feet)
• On-ear buttons for volume, track control and call management
• Integrated microphone for clear voice calls and meetings

Are they comfortable for long listening sessions and travel?
