Description
The BESNOOW I53 is a budget true wireless earbud with a 14.2 millimeter driver, a battery split that is unusually well documented for this bracket, and two claims that do not hold up. The product name advertises IP7 waterproofing, which is not a valid ingress protection code. The bullets advertise lossless CD level audio transmission while naming no codec anywhere on the page.
Who this pair is aimed at
BESNOOW targets everyday use with a workout emphasis. The specific uses field lists gaming, business and fitness, and the recommended uses run from office meetings through running, cycling, snowboarding and skateboarding. The design is a conventional sealing in ear bud with a curved housing and silicone tips, weighing a stated 3.7 grams per earbud. This is a commuter and gym pair rather than a critical listening pair.
The cycling and skateboarding entries carry the usual caveat. A sealing bud reduces your awareness of traffic, and there is no transparency or pass through mode published here to offset that. For road use, an open ear design is the appropriate category, not this one. A sealed pair like this makes far more sense indoors, and if you want the same price bracket with a stated rating and a more careful specification, the Sony WF-C510 publishes an explicit IPX4 code.
Connection: two Bluetooth versions on the same page
The product name and the structured specification both state Bluetooth 5.4. The first feature bullet states, in the same listing, that the earbuds use new Bluetooth 5.3 technology with 30 percent faster transmission. Those cannot both be correct. BESNOOW has not reconciled them, and we are not going to pick one. If the Bluetooth version matters to your purchase, ask the seller before ordering.
Range is given as 15 meters in both the bullet and the specification, above the 10 meter figure most earbuds in this class quote. Treat it as a clear line of sight best case, since walls, bodies and crowded 2.4 GHz environments cut it substantially. A magnetic Hall effect sensor connects the buds as soon as the case opens.
The lossless claim, and why it cannot stand
The third bullet claims lossless CD level audio transmission. No codec is named anywhere on this listing. Not SBC, not AAC, not aptX, not aptX HD, not LDAC. Without a named codec, the only thing that can be assumed is SBC, which is the mandatory Bluetooth baseline and is a lossy codec by design. SBC discards audio data. It cannot deliver a lossless or CD level transmission, and no amount of driver size compensates for that.
Even the codecs that get close come with conditions. LDAC requires both the phone and the earbuds to support it, and most iPhones do not support LDAC at all. aptX HD has the same two sided requirement and is likewise absent from Apple devices. Because BESNOOW names none of them, the lossless claim is unsupported by the published specification.
Battery: 8 hours in the buds, 40 more in the case
This part of the listing is done properly. BESNOOW quotes up to 8 hours of playback on a single charge and up to 48 hours with the charging box, and the structured specification records battery life as 8 hours and carrying case battery average life as 40 hours. Those add up, which is more than can be said for most listings in this catalog, where the total is routinely copied into both fields.
The number that governs a workday is the 8 hour bud figure. The 48 hour headline requires you to carry the 400 mAh case. Charging time is 1.5 hours for both the buds and the case, and there is a dual LED display showing the remaining charge on each. As with every manufacturer, 8 hours is a best case measurement taken at moderate volume, and pushing the volume up in a noisy gym will shorten it. Keeping the level moderate is the right call for the battery and for your hearing.
Fit, controls and the water rating problem
Silicone tips ship in three sizes, small, medium and large, which is the right number and the single most useful fit specification a sealing earbud can publish. Seal decides perceived bass. A 14.2 millimeter driver is large for an in ear housing and BESNOOW leans on it for the bass claim, but a tip that does not seal will make that driver sound thin regardless.
Controls are touch based, with binaural touch sensors handling volume, track skip, pause, calls and voice assistant. Touch controls on a sport bud are a mixed proposition: they have no moving parts to fail, but they misfire when your fingers are wet and they cannot be operated by feel with gloves on.
Now the water rating. The product name says IP7 Waterproof. There is no such code. Ingress protection codes carry two digits, a solids digit and a liquids digit, so a code with one number after IP is malformed. The likely intentions are IPX7, which covers immersion to one meter for thirty minutes, or IP67, which adds dust protection to that. Both are very different from what the fifth bullet describes, which is a nano coating that makes the buds sweat proof and rain proof. Sweat and rain protection is splash level language, closer to IPX4 than to IPX7.
The structured specification simply reads waterproof, with no code at all. So the page offers a malformed code, splash level prose and a bare adjective, and none of them agree. This review will not call the BESNOOW I53 waterproof. Treat the water protection as unstated until BESNOOW publishes a valid two digit code, and note that no consumer IP rating covers seawater or pressurized water, and that seals and coatings degrade with age. A listing that does state a real code is the TAGRY X88 at IPX7, which is what a correctly written immersion claim looks like.
What the listing does not publish, and what else to consider
The noise control field reads sound isolation, which confirms there is no active noise cancellation despite the product name mentioning noise cancelling. The ENC system BESNOOW describes, using four microphones and claiming to filter more than 80 percent of external noise, applies only to your outgoing voice on a call. It does nothing to what you hear, and the 80 percent figure carries no named test standard. Multipoint is not mentioned. Wear detection is not mentioned. There is no companion app and no EQ adjustment described anywhere.
The feed has produced obvious errors worth flagging. The battery field claims one A battery is required and included, which is nonsense on a lithium powered product. The cable feature field reads tangle free on a product with no cable. Ear placement reads over ear while form factor reads in ear. Manufacturer is Shenzhen iSK Technology Co., Ltd while the brand is BESNOOW. The compatibility list runs to dozens of handsets and repeats itself.
Sales position is recorded as ranked 12,833rd in Electronics and 1,285th in earbud and in ear headphones, with a 4.4 star average across 337 ratings. That is a much lower demand position than the brand’s marketing suggests. Be aware too that the I53 model name appears on several separate listings in this catalog, including a second BESNOOW I53 entry, so check the exact identifier before ordering. For direct alternatives at this level, see the Catitru i25 and the Rulefiss Q38, both covered in our earbud headphones section and listed alongside the rest of our true wireless earbud coverage.
Who should buy it, and who should not
Buy the BESNOOW I53 if you want a light, cheap pair with an honest 8 hour bud runtime, three tip sizes and a case that adds 40 hours. Skip it if you need a verified water rating, because the code on the listing is malformed. Skip it if you are buying on the lossless claim, because no codec is published to support it. And ask the seller which Bluetooth version you are actually getting, since the page says 5.4 in one place and 5.3 in another.
