WHYKJTEK A10 Pro Wireless Earbuds Review AAC and SBC Named, IPX7 and a 40 Hour Case Total

Description

The WHYKJTEK A10 Pro does one thing almost no other budget earbud in this catalog does: it names its codecs. The feature copy states a built in AAC and SBC codec chip, and that single line makes this listing more useful than a dozen pages promising Hi-Fi with nothing behind the word. The rest is familiar budget territory, which is 13mm drivers in a four chamber housing, Bluetooth 5.3, an LED charge display on the case, a quoted 8 hour bud runtime, 40 hours in total, and an IPX7 claim. The listing has been live since March 3, 2023, and at the point this data was captured it carried 4,268 ratings averaging 4.4 out of 5, ranked 9,093rd in Electronics and 1,012th in Earbud and In-Ear Headphones. This is a new unit, not a renewed or refurbished one.

Who this set is for, and one caution about who it is sold to

This is an everyday commuter and study earbud. The controls are touch based on both buds and cover playback, volume, calls and the voice assistant, and each bud is quoted at 3.6 grams. Nothing about it is ambitious, and at this price nothing needs to be.

The caution is in the metadata rather than the marketing. The specification table records the department as “unisex child” and the age range as “Teen”, which means this product is being surfaced to people shopping for children and young teenagers. Nowhere on the listing is a volume limit published, and no limiting feature of any kind is described. A sealed earbud with no volume ceiling, handed to a young listener in a noisy environment, is a set that will be turned up until it wins against the ambient noise. We are not going to tell you this product is safe for a child’s hearing, because the listing publishes nothing that would support that. If you are buying for a child, look for a set that states a decibel limit and, more importantly, states whether that limit can be switched off, because a limit that a child can bypass in the app is not a limit.

Connection: the codec line is the useful part

WHYKJTEK states Bluetooth 5.3 with a 15 meter range, and lists HSP, HFP, A2DP and AVRCP profile support, which is the ordinary set every Bluetooth audio device carries and is not a differentiator. Bluetooth 5.3 governs connection stability, power consumption and LE Audio groundwork. It does not improve sound on its own.

AAC and SBC, and what that actually buys you

Naming AAC and SBC is worth something concrete. SBC is the universal floor. AAC is the codec Apple devices default to, so an iPhone owner gets a meaningfully better path here than SBC alone, provided the phone negotiates it. On Android, AAC support varies by handset and by Android version, and some Android implementations handle AAC poorly enough that SBC is the better outcome. What the listing does not claim, and what we will not claim on its behalf, is high resolution or lossless audio. AAC and SBC are both lossy, neither is a high resolution codec, and there is no aptX, aptX Adaptive, aptX HD or LDAC support stated anywhere.

The listing says the A10 Pro “can connect multiple devices at the same time”, which sounds like multipoint but is not stated as multipoint anywhere in the specification. Read it as a marketing paraphrase of ordinary pairing memory unless the seller confirms otherwise, because true multipoint, holding two active host connections at once, is a feature sellers normally name explicitly.

Battery: the eight hour figure and the impossible one

The feature copy separates the numbers properly. Each bud is quoted at a maximum of 8 hours, and the case is quoted as holding roughly five further charges to reach 40 hours in total. Eight hours in a bud is credible for a set with no active cancellation running.

The specification table then disagrees with the marketing copy twice. It gives “Carrying Case Battery Average Life = 32 Hours” where the bullets say 40, and it gives “Carrying Case Battery Charging Time = 40 Hours”, which is not a plausible charge time for any earbud case and looks like the 40 hour playtime figure dropped into the wrong field. Elsewhere the table says charging takes 1.5 hours, which is the realistic number. We are naming these rather than choosing between them: plan around 8 hours per bud and treat the case total as somewhere between 32 and 40 hours depending on which field you believe.

Fit, seal, noise handling and the IPX7 claim

The A10 Pro is a sealed in ear design at 3.6 grams per bud. The listing does not state how many ear tip sizes are supplied, which is a real omission, because on a sealed earbud the tip is the component that decides whether the bass you were promised arrives at all. Assume you may need aftermarket tips and budget accordingly.

The noise cancellation claim needs separating carefully, because the listing makes two different claims in two different places. The feature copy describes a noise reduction chip working with the microphone, “eliminating most of the noise” for the person on the other end of a call. That is call side noise reduction, which changes what your caller hears and does nothing about what you hear. The specification table then lists “Noise Control = Active Noise Cancellation”, which is the other thing entirely. Nothing in the feature copy describes cancellation of ambient noise reaching your ears, and no decibel reduction figure is published. We are treating the ANC entry in the specification table as unverified. If you are buying specifically to quiet engine drone on a commute, buy a set where active cancellation is described in the marketing copy and not just in a database field, and understand that even genuine ANC works on constant low frequency noise and poorly on speech.

IPX7 is claimed in the title and supported by the feature copy, which describes a nano coating protecting the internals, and the specification table records the product as waterproof. IPX7 covers immersion in one meter of fresh water for thirty minutes. It does not cover seawater, chlorinated pools, showers or pressurized water, and the seals that earn the rating degrade with age, heat and repeated charging.

The specification table carries the usual import damage. It lists “Headphones Jack = 3.5 mm Jack” on a true wireless product, “Included Components = Blu-ray”, “Theme = Anime”, a form factor of “Bi-fold”, and an intended use written in Chinese characters. None of it should change your decision, but all of it should lower your confidence in any single field on the page.

What to compare it against

If you want cancellation that is described rather than implied, our write up of the TOZO NC2, where hybrid active cancellation is the headline feature rather than a database entry is the direct comparison. At a step up, the Soundcore Liberty 4 NC, which publishes both its codec list and its cancellation approach shows what a fully documented specification looks like. For a comparable budget set with a published immersion rating, see the TOZO T6, whose water rating appears in the structured specification, and for a longer running budget alternative with an app, the Soundcore P30i, which pairs cancellation with a companion app. The rest of our coverage of this format is under wireless earbuds.

Who should buy it and who should not

Buy the A10 Pro if you want a cheap sealed earbud with AAC named in writing, an 8 hour bud runtime and a genuine IPX7 claim, and you are treating the noise cancellation as a bonus rather than the reason for the purchase. Do not buy it if you need real ambient noise cancellation on a commute, if you need confirmed multipoint, if you need to know the ear tip count before ordering, or if you are buying for a child and need a published, enforceable volume limit. And whatever the fit, do not use a sealed set like this for cycling or driving, because it removes the traffic awareness those activities depend on.
