• Amazon Renewed Beats Powerbeats Pro — biggest strength: a full-featured fitness package — Active Noise Cancelling, Transparency mode, heart rate monitoring, IPX4 sweat and water resistance, and up to 45 hours of battery with the case.
• Amazon Renewed Beats Powerbeats Pro — biggest trade-off: it is a complete two-earbud system with earhooks and a charging case, so it is a bigger commitment than a single replacement part, and it arrives as a renewed item rather than a brand-new retail box.
• TOYOURKI Single Right Ear — biggest strength: it solves one very specific problem — a missing right earbud for a Beats Studio Bud set — at the level of a single part instead of a whole new pair.
• TOYOURKI Single Right Ear — biggest trade-off: it is a replacement piece only, with no noise cancelling, no heart rate sensor and a much shorter warranty period, and it does not fit the Studio Bud+ model.
• Buy the Beats Powerbeats Pro if you are the person doing the training and you want the whole system.
• Buy the TOYOURKI Single Right Ear if you already own a Beats Studio Bud pair and only the right side is missing.
The Powerbeats Pro 2 is built around movement. The earhook design is the giveaway — these are in-ear buds held in place by a hook that wraps over the top of your ear, which is exactly the shape you want when you are running, lifting or doing anything where a normal bud would work its way loose. Beats says the fit was developed through more than 1,500 hours of athlete testing, and the goal is a secure, comfortable hold across different ear shapes and intensities.
The feature list is unusually dense for a workout bud. Active Noise Cancelling is the company's best-performing version, with a Transparency mode when you want to hear traffic or a training partner. There is a heart rate monitor with sensors that pulse more than 100 times per second, which means the buds can report your pulse in real time without a chest strap or watch. An IPX4 rating covers sweat, rain, snow and heat. Battery is rated up to 45 hours with the charging case, the case is 33 percent smaller than the previous generation, and it is the first Beats case with wireless Qi charging. The Apple H2 chip handles the audio processing, and Adaptive EQ measures what you are hearing and adjusts frequencies to suit. Personalized Spatial Audio with dynamic head tracking is on board too. Pairing works one-touch on Apple devices, while Android users get the Beats App for pairing, heart rate monitoring, customizable controls, battery widgets and locating the buds.
TOYOURKI Single Right Ear: Who It's For
This is not a competitor to the Powerbeats Pro 2. It is a spare part, and it should be judged as one. The TOYOURKI Single Right Ear is a replacement earbud for the Beats Studio Bud — and the listing is explicit that it does not fit the Studio Bud+. It is designed to match the original in shape and size so it seats correctly in your existing charging case, and it pairs by simply dropping it in the case so it syncs automatically with your device.
Functionally, you get Bluetooth connectivity, touch controls and a sound profile described as clear highs and rich bass. The enclosure is plastic, the color is gray, and it is built with an ergonomic shape intended for long-wear comfort. The dimensions are listed at roughly 10 by 2 by 2.7 inches for the packaged item.
The case for it is simple economics of the everyday kind: if you have lost or damaged the right earbud of a working Studio Bud pair, replacing that one piece keeps the set functional without buying a new pair. That is the whole pitch, and for the right person it is a sensible one.
Who should buy it: someone who owns Beats Studio Bud earbuds and has a missing or dead right side. Who should skip it: anyone with a Studio Bud+ model, anyone hoping for noise cancelling or heart rate tracking, and anyone who does not already own the charging case it needs to pair and charge. One more thing worth weighing — the warranty is one month from the manufacturer, which is short, so treat this as a part you buy with a clear-eyed expectation rather than a long-term investment.
Side-by-Side: Which Should You Choose?
• Best for replacing one lost earbud → TOYOURKI Single Right Ear. It exists for that single job and nothing else.
• Best for noise control → Amazon Renewed Beats Powerbeats Pro. Active Noise Cancelling plus a Transparency mode. The TOYOURKI bud offers neither.
• Best for workout and fitness tracking → Amazon Renewed Beats Powerbeats Pro. Heart rate monitoring, IPX4 sweat and water resistance, and secure earhooks.
• Best for staying put during hard training → Amazon Renewed Beats Powerbeats Pro. The earhook fit is the entire design premise.
• Best for lowest outlay → TOYOURKI Single Right Ear, as long as you already own the Studio Bud case and the left earbud. Check the current price on Amazon before deciding.
• Best for Android flexibility → Amazon Renewed Beats Powerbeats Pro. The Beats App unlocks pairing, heart rate monitoring, custom controls and location features.
• Best for a complete, self-contained system → Amazon Renewed Beats Powerbeats Pro. The TOYOURKI piece is a component, not a set.
In my opinion, the Amazon Renewed Beats Powerbeats Pro is the one I would buy — if I am shopping for earbuds to actually use, it is the only one of the two that is a complete product. Noise cancelling, heart rate monitoring, IPX4 protection and up to 45 hours of battery with the case cover almost everything a training-focused listener needs, and the earhook design is the right answer for movement. I would only go with the TOYOURKI Single Right Ear in one scenario: I already own Beats Studio Bud earbuds, the right side is gone, and I want to keep the pair alive rather than start over. Different problems, different answers — but for most readers landing on this page, the full system wins.
No. The listing states it fits the Beats Studio Bud and specifically not the Bud+. Check your model before ordering, because a Bud+ owner would end up with a part that does not match.
Does the TOYOURKI replacement earbud have noise cancelling or heart rate monitoring?
No. It offers Bluetooth audio, touch controls and automatic pairing through your charging case. Noise cancelling, Transparency mode and heart rate sensing are features of the Powerbeats Pro 2, not of this replacement bud.
Yes. It works with both Apple and Android. Android users get the Beats App, which adds one-touch pairing, heart rate monitoring, customizable controls, battery status widgets and location features.
Ask one question: do I need a whole pair of earbuds, or one replacement part? If it is a whole pair for training, take the Powerbeats Pro 2. If it is a missing right earbud for a Studio Bud set you already own, take the TOYOURKI. When price matters to you, check the current price on Amazon before you commit.
