Description
The Powerbeats Pro 2 is Beats returning to its hooked training earbud after six years, now on the Apple H2 chip with active noise cancellation, transparency mode and a heart rate sensor in each bud. It is the most feature dense product in this batch. It is also rated IPX4, which is a much weaker water rating than a training earbud’s marketing usually implies, and that deserves stating early.
Who this is for
This is a gym and training earbud built around the hook. Beats reinforced the ear hook with a nickel titanium alloy and says the result is 20 percent lighter than the previous generation, with five ear tip sizes in the box. Beats states that over 1,500 hours of athlete testing informed the fit. That is Beats’ own figure and its own testing, not ours, and it describes fit development rather than a measured outcome.
The recommended uses in the attribute table include cycling, and that needs the same flag it gets on every sealing earbud. The Noise Control field reads Active Noise Cancellation and Sound Isolation, so the buds both seal and cancel, which removes exactly the traffic cues a rider needs. There is a transparency mode here, which is a real mitigation and better than nothing, but it depends on you remembering to enable it. Anyone riding on roads should consider a design that leaves the ear canal open by default, and our open ear headphone reviews cover those.
Connection, the H2 chip and the codec question
Beats specifies Class 1 Bluetooth and the Apple H2 chip. On Apple devices that unlocks one touch pairing, automatic switching between devices signed into the same account, Audio Sharing, hands free Siri and Find My. On Android the Beats App provides one touch pairing, heart rate monitoring, customizable controls, battery widgets and Locate My Beats, so this is genuinely a two platform product rather than an Apple only one.
No audio codec is named anywhere on the listing. Beats hardware on Apple devices runs AAC, and there is no aptX or LDAC support in any H2 product, so an Android listener gets AAC or SBC depending on the phone. That means no high resolution or lossless transport is available here on either platform, and Beats does not claim one. Personalized Spatial Audio with dynamic head tracking is an Apple ecosystem feature and is a spatial processing effect rather than a resolution improvement. Adaptive EQ uses the microphones to adjust frequency response to what is actually reaching your ear, which is a real feature and depends entirely on getting the tip seal right.
The attribute table claims Wireless Communication Technology of Bluetooth and Wi-Fi. There is no Wi-Fi in this product. It also lists Included Components containing Powerbeats Pro 4, which is a typo for Pro 2 and not a fourth generation product.
Noise cancelling and the heart rate sensor
Beats describes this as the best performing active cancellation it has developed, with transparency mode alongside it. No decibel figure and no test standard are published anywhere on the listing, so there is nothing to attribute. What cancellation can do is well established: it works on constant low frequency noise such as ventilation, treadmill motors and road rumble, and poorly on speech and impulsive sounds such as a dropped plate. No earbud makes a gym silent. When the drone goes but the voices remain, the temptation is to raise the volume until they go too, and that is the behavior that damages hearing.
The heart rate sensors pulse over 100 times per second to read your pulse in real time, and the data surfaces in the Beats App on Android and in Apple’s fitness stack. This is a fitness sensor rather than a medical device, Beats makes no medical claim for it, and neither does this review. Optical heart rate accuracy depends on skin contact and varies with motion, and the ear is generally a good site for it, but nothing on the listing quantifies the accuracy.
Battery, split the way the listing does not
The headline is up to 45 hours, and the attribute table repeats 45 in both the Battery Life field and the Carrying Case Battery Average Life field, which is the same number filed twice and tells a shopper nothing about the split. The detailed specification block resolves it: up to 10 hours of continuous bud playback, up to 45 hours total with the charging case. Ten hours is the figure that governs a training session; 45 is the combined number.
Fast Fuel gives up to 1.5 hours of playback from a 5 minute charge. The case is 33 percent smaller than the previous generation and is the first Beats case with Qi wireless charging. One practical warning from the listing itself: the USB-C to USB-C charging cable is not included in the box. As with every quoted playtime, 10 hours assumes moderate volume, and active cancellation costs battery with no separate figure published for it.
Fit, controls and the IPX4 rating
Five ear tip sizes plus a reinforced adjustable hook is the widest fit adjustment available in this catalog, and it matters twice over: the seal decides the bass, and it decides how much the cancellation and the Adaptive EQ have to work with. Controls are physical on ear buttons with tactile volume rockers rather than touch pads, which is the better choice on a training product where a sweaty finger on a capacitive surface is a track skip waiting to happen. Beats publishes real weights, which is rare here: 8.7 grams per bud, 69 grams for the case, 77.7 grams together.
The water rating is IPX4, stated plainly in the product title, and it is the specification most likely to be misread. IPX4 means protection against splashing water from any direction. It covers sweat, rain and snow, which is exactly what Beats claims. It does not cover immersion, so these are not waterproof, should not be showered in and should not be swum in. The X in the code also means no dust rating was tested at all, which is worth knowing for gym chalk and trail dust. The attribute table softens this further to Water Resistant with no code. For genuine immersion or dust protection a training earbud needs IP67 or IP68, as on the Soundcore Sport X20 with its stated IP68. No IP rating covers seawater or high pressure water, and seals degrade with age and sweat exposure.
Alternatives and duplicates
The previous generation is also in this catalog as the Beats Powerbeats Pro with the H1 chip, which has no active cancellation and charges over Lightning, so the generational gap is substantial. Within the Beats range the Beats Fit Pro uses a wingtip instead of a hook and the Beats Studio Buds Plus drop the sports fit entirely. The wider group sits in our wireless earbud reviews. The listing is dated 11 February 2025 under model number MX723LL/A and the age range field reads Adult and Teen, with no volume limiting feature published.
Who should buy it and who should not
Buy the Powerbeats Pro 2 if you train indoors, want a hook that adjusts, and will use the heart rate sensor and the app. Five tip sizes, physical buttons, published per bud weights and genuine Android support make this a well specified product by the standards of this catalog.
Do not call it waterproof and do not swim in it, because IPX4 is splash protection only and carries no dust rating. Do not expect high resolution audio, because there is no aptX or LDAC on any H2 product. And budget for a USB-C cable, because one is not in the box.
