Description
The Hupoaf H87 is a hooked sports earbud with a Bluetooth 5.4 radio, a 10 hour bud runtime and four microphones for calls. Its specification is more internally consistent than most listings in this bracket, which makes the one place it goes badly wrong easier to isolate: the water rating, where Hupoaf publishes an invalid code and then claims immersion on the strength of it.
Who this is built for
The hook is the whole design argument. A silicone over ear hook holds the bud against the ear through running, jumping and lifting, and it is the answer to the single most common complaint about sports earbuds, which is that they migrate out of position under movement. Hupoaf lists the H87 for running, cycling and gym use, and the attribute table files it under a running and workout theme.
Cycling on that list deserves the same flag it gets everywhere else. The Noise Control field reads Passive Noise Cancellation and Sound Isolation, which means the bud seals and blocks sound physically. A sealing earbud on a road bike removes the traffic cues that keep you safe, and no listing recommendation changes that. If you ride on roads, an open design that leaves the canal clear is the correct product category, and our open ear headphone reviews cover that group.
Connection, and the difference between ENC and ANC
Hupoaf specifies Bluetooth 5.4 with a 15 meter range and describes faster, more stable pairing with fewer dropouts. That is an accurate description of what a Bluetooth version change does. It affects connection robustness, power consumption and profile support, and it does not improve sound quality.
The noise cancelling language needs care. The product title advertises four ENC noise cancelling microphones. ENC is microphone side processing that cleans up your voice for the person on the other end of a call, and it does nothing at all for what you hear. The attribute table confirms this by listing the Noise Control as passive isolation only, with no active cancellation entry. So the H87 has no active noise cancellation for the listener, and the marketing language is technically accurate but easy to misread. If active cancellation is what you want, a set that publishes it explicitly, such as the Soundcore Sport X20 with manual and adaptive modes, is the comparison to make.
No audio codec is named anywhere on this listing. There is no SBC, AAC, aptX or LDAC statement, so SBC is the only transport that can be assumed and the premium audio language in the bullets has nothing behind it. Multipoint, wear detection, transparency mode and app support are all unmentioned and should be treated as absent.
Battery, and a rare case of the numbers agreeing
Hupoaf publishes 10 hours from a single charge and 50 hours in total with the case, and the attribute table backs it with a Battery Life of 10 Hours and a Carrying Case Battery Average Life of 40 Hours. Ten plus forty is fifty, so for once the marketing figure and the structured data reconcile exactly. That consistency is worth crediting, because it is uncommon across this catalog.
Both figures are still best case, measured at moderate volume with no extra processing. The four ENC microphones run only during calls, so call time will fall short of music time and Hupoaf publishes no separate talk figure. Charging is USB C and both the buds and the case are quoted at 1.5 hours to full. An LED display on the case shows the charge level and charging state.
Fit, tips and a water rating that is not a real code
The hook does most of the fit work, and the bud weight is given consistently as 4 grams and 0.141 ounces, which for once agree with each other. What is missing is the ear tips. The Included Components field lists two earbuds, a charging case, a charging cable and a user guide, and no ear tips of any kind. That is a genuine gap on a sealing in ear design, because the seal is what decides whether the deep bass Hupoaf advertises actually reaches you, and no tip count or size range is published anywhere. Buyers should assume they may need to source tips separately.
The water rating is the serious problem. Hupoaf writes IP7 in the product title and in a bullet, and the bullet goes further, stating that the earbuds can resist sweat, rain and even short term immersion in water. IP7 is not a valid ingress protection code. A valid code requires two positions, one for solids and one for liquids, so the intended claim was almost certainly IPX7. That distinction is not academic here, because the listing is using the invalid code to support an explicit immersion claim. The attribute table adds only Water Resistance Level: Waterproof, again with no code. Since no valid rating is published, the defensible position is that sweat and rain are covered and immersion is unproven, and the immersion sentence in the bullet should not be relied on. No IP rating covers seawater, hot water or high pressure water in any case, and the seals that produce a rating degrade with age and sweat exposure.
What is odd in the data, and the alternatives
Two fields contradict the product. Form Factor reads Over Ear, which describes a full sized headphone rather than an in ear bud on a hook, while the Ear Placement field correctly reads In Ear and Earpiece Shape reads Hook. The Batteries field says one A battery is required, which is inherited nonsense for sealed lithium cells. Product Dimensions read 1.18 by 0.79 by 1.18 inches, the same figures that appear on several unrelated listings in this catalog, which suggests a shared supplier template rather than a measurement of this product.
Nothing is published for driver size, driver type, frequency response, impedance or sensitivity. Two marketing claims are worth attributing rather than repeating: Hupoaf states it has served more than a million customers worldwide, and offers a one year warranty with 24 hour support. The listing showed 4.5 out of 5 from 988 ratings, ranked 1,092nd in Electronics and 172nd in earbud and in ear headphones, first available in December 2024.
For alternatives, the Stiive U8I sports earbuds use the same hook approach at a similar level, the Raycon fitness earbuds come from a brand with a wider support presence, and the JOYWISE U18C sports set is another hooked option. The full comparison group is in our wireless earbud reviews.
Who should buy it and who should not
Buy the H87 if a hook is what keeps earbuds in your ears, if 10 hours per charge matters, and if you value a listing whose battery numbers actually reconcile. On that last point it does better than most of the competition here.
Do not buy it expecting active noise cancellation, because the ENC microphones only help your callers. Do not swim or shower in it on the strength of the immersion sentence, because the published code is not a valid IP rating. And check the ear tip situation before ordering, because none are listed in the contents.
