If you want a premium, standalone wireless earbud system with active noise cancellation and high-fidelity Bluetooth 5.3 for general commuting or travel, choose Avantree Relay; if you need an exact, cost-effective replacement part to restore a broken Beats Fit Pro set for jogging, choose TOYOURKI Single Right Ear.
• Avantree Relay: Delivers a complete listening experience with hybrid ANC and aptX-Adaptive support, but requires you to buy the full unit including earbuds and case rather than fixing a specific existing pair.
• TOYOURKI Single Right Ear: Offers a seamless, 1:1 functional replacement for lost Beats Fit Pro buds with identical ANC and touch controls, but is strictly limited to users who already own the original Beats charging case.
• Best for: The Avantree Relay fits travelers and commuters seeking a new, versatile audio setup, while the TOYOURKI single bud is the only logical choice for anyone who has lost one side of their Beats Fit Pro and wants to keep using their current case.
The Avantree Relay stands out as a comprehensive solution for those who need a high-quality audio adapter and earbuds in one package. It is designed to bridge the gap between non-Bluetooth devices and modern wireless headphones, making it particularly useful for environments like airplanes, gyms, or home theaters where audio output is via AUX cables. With its inclusion of dual 3.5mm adapters, this system ensures compatibility regardless of the connector type on your device, offering a level of versatility that many standalone earbuds simply cannot match.
What truly sets this product apart for active users is the combination of Bluetooth 5.3 technology and aptX-Adaptive codec support. This pairing allows for low-latency transmission of high-quality audio, which is critical when watching videos or engaging in calls where sound synchronization matters. The system also features hybrid Active Noise Cancellation capable of blocking up to 24dB of environmental noise, providing a quiet sanctuary even in loud settings. For someone looking for the best wireless earbuds for jogging or running in noisy urban environments, the ability to tune out traffic and crowd noise without sacrificing connection stability is a significant advantage.

However, this is not a product for everyone. If you are specifically looking to replace a single missing earbud from an existing set of Beats Fit Pros, the Avantree Relay will not work for you. It is a self-contained system with its own Orange-colored, rounded-tip in-ear design and a dedicated charging case that displays battery levels. You must purchase the entire bundle to get started. It is ideal for buyers who want a fresh start with advanced features like Transparency Mode to stay aware of surroundings, but it is overkill if you just need a simple, fixed component for an existing ecosystem.
The TOYOURKI Single Right Ear exists for a very specific problem: a lost or damaged right earbud from your Beats Fit Pro set. Unlike the Avantree Relay, which is a brand-new, independent product, this item is engineered to integrate perfectly into your existing charging case. It matches the original design, size, and materials exactly, meaning there is no need for modifications or awkward fitting issues. If you have been frustrated by the inability to use your left earbud because the right one went missing, this replacement restores the full stereo experience immediately.
Functionally, this single bud replicates the performance of the original Beats Fit Pro. It supports the same Bluetooth 5.2 connectivity, touch controls, and voice assistant access. Crucially, it retains the Active Noise Cancellation and transparency mode features found in the original hardware. This means that whether you are deep in a workout session or navigating a busy commute, the audio quality, crisp highs, and deep bass remain consistent with what you paid for originally. The build uses durable plastic and silicone materials designed to withstand daily wear and tear, ensuring that the replacement feels just as comfortable and secure during extended listening sessions as the original pair did.
This product is exclusively for owners of Beats Fit Pro headsets. It is not a standalone headset you can use with other devices or cases. Its value proposition is entirely rooted in cost-effectiveness; it allows you to extend the life of your favorite audio gear without spending hundreds on a brand-new full set. If you are a runner who relies on the secure fit of the Beats Fit Pro wings and has recently lost the right side, this is the most practical path forward. However, if you do not own a Beats Fit Pro, this product offers zero utility to you.
• Best for battery monitoring → Avantree Relay, as it includes a dedicated case display to check charging status, whereas the TOYOURKI relies on the case's existing indicators without a separate display feature.
• Best for raw connection speed → Avantree Relay, which utilizes the newer Bluetooth 5.3 standard compared to the Bluetooth 5.2 found in the TOYOURKI replacement.
• Best for audio fidelity standards → Avantree Relay, thanks to its support for aptX-Adaptive codec, which is not listed as a feature for the TOYOURKI single bud.
• Best for fixing a broken pair → TOYOURKI Single Right Ear, since it is the only option designed to sync directly with an existing Beats Fit Pro charging case.
• Best for airplane travel → Avantree Relay, because it comes with dual 3.5mm adapters specifically for connecting to in-flight entertainment systems.
• Best for immediate budget savings → TOYOURKI Single Right Ear, as replacing one bud is significantly cheaper than purchasing a completely new system like the Avantree Relay.
• Best for joggers needing ambient awareness → Avantree Relay, which explicitly highlights Ambient Mode to let environmental sounds through, a feature present in both but essential for the standalone nature of the Relay.
• Best for color matching → TOYOURKI Single Right Ear, which is available in White-Right to match the original Beats aesthetic, whereas the Avantree Relay is sold in Orange.
For my money, I would recommend the Avantree Relay if you are building a new audio setup for jogging or commuting. The inclusion of Bluetooth 5.3 and aptX-Adaptive support provides a more future-proof connection, and the hybrid ANC offers superior noise isolation for a standalone device. It is the better choice for a rotatable ear cups bluetooth headset for jogging scenario where you need a complete, reliable system that doesn't depend on owning another brand's hardware. However, if you are a Beats Fit Pro owner who has lost a bud, the TOYOURKI is the only sensible path. But for a primary recommendation for a new purchase, the Avantree Relay offers more versatility and advanced features.
Yes, the Avantree Relay includes dual 3.5mm adapters that make it usable on any flight, regardless of the specific connector type on the aircraft's entertainment system.
No, the TOYOURKI Single Right Ear is designed specifically to sync with the existing Beats Fit Pro charging case and is not a standalone unit for other devices.
Both products feature Active Noise Cancellation, but the Avantree Relay specifies it can block up to 24dB of environmental noise, whereas the TOYOURKI mirrors the original Beats performance.
Neither product is a headband; however, the Avantree Relay features a dedicated Transparency Mode (Ambient Mode) to help joggers stay aware of their surroundings while listening.
