If you want open-ear comfort and awareness for teaching, choose OpenRock Pro Open Ear; if you need noise-cancelling earbuds and a Bluetooth transmitter for travel, choose Avantree Relay. For teachers moving between a classroom, a commute, and personal listening, these products serve very different needs: OpenRock is built around wearing earbuds while staying aware of your surroundings, while Relay is a travel-oriented audio bundle designed to bring wireless listening to an airplane’s headphone jack.
• OpenRock Pro Open Ear: Around-ear hooks leave the ear canal open, and its battery is rated for up to 19 hours per charge, with 27 more hours from the case. The trade-off is that it does not provide noise control.
• Avantree Relay: Pairs a Bluetooth transmitter with ANC earbuds, including a transmitter that can connect to two pairs of Bluetooth headphones. The trade-off is that its defining travel feature depends on a 3.5 mm audio source, and the Relay transmitter itself is not meant for phones, TVs, musical instruments, or real-time monitoring.
• Choose OpenRock if you want open-ear listening, long stated battery life, and awareness of nearby sounds.
• Choose Avantree Relay if you want to use wireless headphones with airplane entertainment and reduce surrounding noise with the included ANC earbuds.
OpenRock Pro Open Ear is for someone who wants sound without inserting earbuds into the ear canal. Its silicone hooks sit around the ear, and the open-ear design is intended to preserve awareness of nearby sounds. That combination makes it a natural fit for teachers who may want audio during a planning period, a walk, or another moment when staying alert to their surroundings matters. It is also designed for sports and outdoor activities, with an IPX5 water-resistance rating.
The battery figures are a standout: up to 19 hours of listening and call time at 70% volume from a charge, plus a further 27 hours from the case. The product also lists a dynamic driver, TubeBass bass enhancement, Bluetooth 5.2, and four microphones with cVc 8.0 call noise reduction. Those details point to a feature set for everyday listening and calls, rather than a bundle centered on connecting to in-flight entertainment.
The trade-off is equally clear: OpenRock does not offer noise control. Its open design is useful when you want to hear around you, but it is not the pick for shutting out engine noise or a busy room. If you are searching for sleep headphones for teachers, consider what this product actually offers: it is an around-ear open-ear design, not a sleep-specific headband. And if your main goal is active noise cancellation, Avantree Relay’s included earbuds are the closer fit.

Avantree Relay is a two-part listening setup: a Bluetooth transmitter and the Avantalk Infinity NC earbuds. The transmitter plugs into a 3.5 mm audio jack, such as the one used by in-flight entertainment, then sends audio wirelessly to Bluetooth headphones. It can connect to two pairs of Bluetooth headphones, which gives it a practical use when two people want to listen to the same source.
The included Infinity NC earbuds add active noise cancellation using a six-microphone system. They also support aptX Adaptive, LE Audio, and Auracast compatibility, with use described for compatible phones, PCs, TVs, and public Auracast broadcasts. That makes the earbuds more flexible than a travel-only accessory, though compatibility depends on the device or broadcast in question. For a teacher who travels and wants to watch a film on a plane with wireless earbuds, this bundle has a clear purpose.
There are limits to keep in mind. The Relay transmitter is designed for 3.5 mm audio sources; it is not a general-purpose adapter for phones, TVs, assistive listening devices, musical instruments, or real-time monitoring. Its battery life is listed as up to 25 hours. This is also not an open-ear product: the included earbuds use ANC to reduce surrounding sound, the opposite priority from staying aware of the room. If you want a multipoint headband headphones for teachers setup, neither product is a headband; OpenRock uses ear hooks, while Relay is a transmitter paired with earbuds.
• Best for open-ear listening → OpenRock Pro Open Ear. Its ear hooks leave the ear canal open, making it the clearer choice when you want audio without fully blocking nearby sounds.
• Best for airplane entertainment → Avantree Relay. Its transmitter connects to an airplane’s 3.5 mm audio jack and sends the audio to Bluetooth headphones.
• Best for active noise cancellation → Avantree Relay. The included Infinity NC earbuds use a six-microphone ANC system for reducing surrounding noise.
• Best for long stated listening time per charge → OpenRock Pro Open Ear. It lists up to 19 hours from the earbuds at 70% volume, compared with up to 25 hours for the Relay transmitter; these figures refer to different parts of the products, so they are not a direct like-for-like battery comparison.
• Best for sharing one audio source between two listeners → Avantree Relay. The transmitter supports two pairs of Bluetooth headphones.
• Best for outdoor movement and sweat resistance → OpenRock Pro Open Ear. Its sports-focused around-ear design and IPX5 water resistance suit running, cycling, and hiking better than a travel adapter and ANC earbud bundle.
• Best for a teacher who wants to stay more aware of a classroom or nearby people → OpenRock Pro Open Ear. Its open-ear design is the more suitable match; ANC earbuds are intended to reduce surrounding noise.
• Best for switching between travel audio and compatible personal devices → Avantree Relay’s Infinity NC earbuds. The earbuds are described for compatible phones, PCs, TVs, LE Audio devices, and Auracast broadcasts, while the Relay transmitter has narrower source-device limits.
For a teacher choosing one of these, I would pick OpenRock Pro Open Ear if the priority is comfortable, open-ear listening and awareness during everyday routines. Its long stated battery life and sports-ready design are useful strengths. I would choose Avantree Relay instead for frequent flights, airplane-jack compatibility, and noise cancellation. My recommendation for teachers is OpenRock when staying connected to the room matters more than blocking it out.
FAQ
Which is better for teachers: OpenRock Pro Open Ear or Avantree Relay?
OpenRock is the more fitting choice when open-ear listening and nearby sound awareness matter. Avantree Relay is better suited to teachers who want ANC earbuds and a way to listen wirelessly to airplane entertainment.
The Relay transmitter is designed for 3.5 mm audio sources and is not intended for phones or TVs. The included Infinity NC earbuds can be used with compatible phones and TVs, as well as other listed compatible devices.
No. Its listed noise control is “None,” and its open-ear design is intended to keep the listener aware of the environment. For active noise cancellation, the Avantree bundle’s Infinity NC earbuds are the relevant option.
OpenRock lists up to 19 hours of listening and call time from the earbuds at 70% volume, plus 27 hours from the charging case. Relay lists up to 25 hours for the transmitter. Because those figures describe different components and use cases, they do not establish a direct battery-life winner.
