If you want a rugged, noise-canceling audio system designed for high-decibel industrial environments with active microphone support, choose Avantree Relay; if you need a protective silicone shell to keep your existing premium headphones clean and scratch-free during gym sessions or commutes, choose Maxjoy AirPods Max Case. These two products serve fundamentally different purposes in the world of personal audio gear, and confusing them is a recipe for buyer's remorse. One is a complete listening solution built to survive the chaos of a warehouse floor, while the other is an accessory intended solely for preservation and aesthetics.
• Avantree Relay: Its greatest strength is the combination of Bluetooth 5.3 connectivity, hybrid Active Noise Cancellation (ANC), and a built-in microphone, making it ideal for communication in loud spaces; its trade-off is that it is a standalone earbud system rather than a cover for another device.
• Maxjoy AirPods Max Case: Its biggest advantage is the comprehensive, three-part protection suite made of soft TPU and silicone that guards against sweat, dust, and drops without adding bulk; its limitation is that it offers no audio features, battery life, or sound isolation of its own.
• Who picks which: Choose the Avantree Relay if you are looking for the best headband headphones for warehouse work or ipx7 waterproof bluetooth headphones for warehouse work scenarios where hearing protection and clear calls are mandatory. Choose the Maxjoy case only if you already own Apple AirPods Max and simply need to protect them from the elements.
The Avantree Relay is engineered for people who need to hear clearly when the world around them is screaming. In a setting like a busy distribution center or a manufacturing plant, that level of attenuation isn't just a luxury; it is often a necessity to prevent fatigue and maintain focus. The inclusion of Transparency Mode adds another layer of utility, allowing the user to switch off the noise cancellation instantly to hear alarms, coworkers, or machinery approaching without having to remove the earbuds.
Connectivity is where this unit truly shines for professional use. With Bluetooth 5.3 technology and aptX-Adaptive codec support, the Relay ensures a stable connection with low latency. This is critical for anyone using with microphone earphones for warehouse work where real-time communication is part of the job. The ability to connect to any device via AUX output means it can pair with older factory radios, TV monitors on the floor, or modern smartphones alike. The dual 3.5mm adapter included suggests a versatility that transcends typical consumer electronics, targeting environments where standard Bluetooth ports might not exist on every piece of equipment.
However, this product is not for everyone. If you are looking for a simple storage solution or a way to wrap up your expensive headphones, this is the wrong tool. The design features rounded tips and an in-ear placement, which provides a secure fit but requires a different maintenance routine than over-ear cans. The battery display on the case allows you to monitor power levels easily, ensuring you don't get caught mid-shift without charge. You should skip this product if you prefer over-ear comfort or if you already have a fully functional headphone setup that you just want to store safely.

On the other side of the aisle sits the Maxjoy AirPods Max Case, which serves a completely different master. This is not a replacement for headphones; it is a shield. The product description highlights a "3 in 1" protective set comprising a headband cover, ear cups covers, and earpad covers. The material composition is key here: a mix of Silicone and Clear Thermoplastic Polyurethane (TPU). This combination is chosen specifically for its tactile qualities—soft, lightweight, and smooth to the touch—while offering resistance to fingerprints and scratches. For owners of the Apple AirPods Max, who know how easily those metal frames and leather-like cushions can show wear, this offers peace of mind.
The water resistance level is listed as Waterproof, and the text explicitly mentions protection against sweat at the gym. While the original AirPods Max are not technically rated for heavy sweat exposure by the manufacturer, adding these silicone covers creates a barrier against moisture, dirt, and dust. The precise cutouts ensure that the headphones can still enter sleep mode when stored in their Smart Case, preserving the smart functionality of the original device. The clear nature of the TPU ear cup covers allows the original aesthetic of the headphones to remain visible while providing a layer of defense against scuffs and impact.
This product is strictly for the owner of the specific Apple hardware it is designed for. It does not offer any audio enhancement, noise cancellation, or wireless transmission capabilities. If you do not own the AirPods Max, this item has zero utility for you. It is also not suitable for general-purpose audio gear; it is a bespoke accessory. You should buy this only if you plan to use your expensive headphones in environments where they might encounter sweat, grime, or accidental bumps, and you want to maintain their resale value or pristine appearance.
• Best for battery life and independence → Avantree Relay: It includes its own charging case with a battery display and operates entirely wirelessly via Bluetooth 5.3, whereas the Maxjoy case relies on the host device's internal battery.
• Best for active noise reduction → Avantree Relay: With hybrid ANC blocking up to 24dB of sound, it actively manages your auditory environment; the Maxjoy case offers zero acoustic isolation.
• Best for durability in wet conditions → Avanteye Relay: Designed with waterproof considerations and sweatproof materials for active use, while the Maxjoy case focuses on protecting the exterior finish of the headphones from sweat and dirt.
• Best for communication in noisy areas → Avantree Relay: Features a built-in microphone and transparency mode essential for workers needing to talk while wearing headphones.
• Best for preserving high-end aesthetics → Maxjoy AirPods Max Case: The clear TPU and silicone materials are designed to keep the original look intact while preventing scratches and fingerprints.
• Best for universal compatibility → Avantree Relay: Works with planes, TVs, gym equipment, and any AUX-output device, unlike the Maxjoy case which fits only one specific model.
• Best for gym sweat protection → Maxjoy AirPods Max Case: Specifically marketed to protect cushion surfaces from sweat, though it does not make the headphones themselves sweat-proof internally.
• Best for all-day shift work → Avantree Relay: The long-lasting battery and noise-canceling features make it superior for extended periods in demanding work environments.
When I weigh the practical needs of someone working in a warehouse or a loud industrial setting, the Avantree Relay is the undisputed winner. It solves the actual problem of hearing safety and communication clarity. The Maxjoy case is a nice accessory, but it is merely a cosmetic and physical guard for a device that is not inherently designed for the rigors of that environment. If you are looking for the best headband headphones for warehouse work, the Avantree Relay provides the necessary tools to function effectively. I would personally choose the Avantree Relay because it transforms your listening experience into a functional tool for productivity and safety, rather than just a way to store your headphones.
The Avantree Relay is designed for active use and includes sweat-resistant features suitable for gym and work environments, while the Maxjoy case is explicitly waterproof and protects against sweat for the AirPods Max.
No, the Maxjoy package contains only the protective covers for the headband, ear cups, and earpads; the Apple AirPods Max headphones must be purchased separately.
Yes, the Avantree Relay includes dual 3.5mm adapters that allow it to connect to any device with an AUX output, including older airplane audio jacks and various electronic equipment.
According to the specifications, the precise cutouts in the Maxjoy design allow the headphones to enter sleep mode automatically when placed in their Smart Case without obstruction.
