Soft-tip stem earbuds with four microphones for calls, big 14.2mm drivers and a slim case that shows the battery in digits for up to 48 hours.
Many budget stem buds carry one mic per side, and the BESNOOW I53 carries four. More mics give the ENC, environmental noise cancellation, more to work with: it compares what each one hears, keeps the sound coming from your mouth and turns down the rest. BESNOOW says it filters out more than 80 percent of outside noise on calls.
That makes the I53 a friendly pick for anyone whose day is full of calls from imperfect places:
ENC is a call feature. It cleans up what the other person hears, not what you hear, and the I53 has no active noise cancelling for music. The silicone tips do block a fair share of outside sound simply by sealing the ear, so the music side is still pleasant on a bus.
Clear calls also depend on how the buds sit. The mics live on the stems, so a bud rotated with the stem pointing down toward your mouth hears you best. If callers say you sound distant, twist each bud a few degrees until the stem lines up with your jaw.
The pairing steps for phones and laptops cover Windows and Mac menus, including the moment when the buds show up under two names and what to do about it.

The I53 runs up to 8 hours per bud charge, and its 400mAh case brings the total to 48 hours. The case is slim for that capacity, about 60 × 28 × 20mm and 35 grams, so it sits flat in a jacket pocket instead of bulging.
Dual LED digits on the case show the power left in the case and the buds, meaning you never have to guess before heading out. A full case refill takes about 1.5 hours.
Keep the I53 going all week with four small habits:
With two to three hours of listening a day, 48 hours works out to charging the case roughly every two and a half weeks. Heavy call days drain faster, since the mics and radio work harder than during music, but a full working day still fits well inside one bud charge.
The slim case has a practical upside on travel days. It fits in a shirt pocket or the small zip pocket of a running belt, and a single charge covers a long weekend away with room to spare, so the cable can stay in the suitcase.
If a bud ever reads zero when it should be full, lift it out and reseat it firmly; the charging pins need solid contact. The charging help explains what the case lights and numbers are telling you.
BESNOOW gives the I53 touch sensors on both buds and splits the jobs between them. That means you can go to the previous song as well as the next one, change the volume and pause, all from your ears. Many cheaper pairs only skip forward.
The I53's touch pads cover:
Which tap does what is printed in the small manual, and the patterns follow the common i12 layout covered on the tap cheat card. Give yourself a day to learn them; after that, the phone can stay put in a pocket.
The Hall-effect switch is the other everyday convenience. A tiny magnet sensor notices when a bud leaves the case, powers it on and reconnects it to your last device, which is why the I53 is ready by the time it reaches your ear. Bluetooth 5.4 keeps the link steady up to about 15m in open space.
For the fit, the I53 uses a curved shell that follows the shape of the outer ear, with S, M and L silicone tips. At 3.7 grams per bud, it is light enough for a long run, and the IPX7 nano-coating deals with sweat and rain. Wipe the buds dry before they go back in the case, because water on the charging pins is the usual cause of charging trouble later.
Both I53 colors share the same four mics, 14.2mm drivers, 48-hour case and two-year warranty. Rose gold gives the case a warm metallic tint you can find quickly in a bag, and white keeps the clean classic look.
The pair most shoppers weigh the I53 against is the Btootos A90 Pro, which uses the same driver size and Bluetooth version.

A quick checklist before ordering:
Between the two I53 colors, think about where the case will live. Rose gold hides fingerprints and small scratches a little better than gloss white, and it is easier to find at the bottom of a dark bag. White suits a white phone and the classic stem look, and a weekly wipe keeps it bright.
For most first-time buyers who talk on the phone a lot, the I53's extra mics and longer case make it the easier recommendation of the two.
Four, working together with ENC to keep your voice clear and push background noise down on calls.
Up to 8 hours per charge and 48 hours with the 400mAh case. The case refills in about 1.5 hours.
The buds are IPX7 rated with a nano-coating, so sweat and rain are fine. Keep the case dry and dry the buds before charging.
No. Its ENC works on calls; for music, the silicone tips block outside sound passively.
Rose gold and white, identical inside.
