Description
What Raycon built here
The Raycon Fitness Earbuds, model RBE745-21E, are a sealed in-ear true wireless earbud aimed at training. Amazon first listed them in August 2021 and they have gathered roughly 8,742 ratings at a 4.2 star average, ranking 1,978th in Electronics and 284th among earbud and in-ear headphones. Country of origin is listed as the USA, which is unusual in this category.
On features this is one of the better equipped products in the catalog. Raycon publishes active noise cancellation, an awareness mode that lets ambient sound through, multipoint pairing to two devices at once, single earbud use, ear stabilizers alongside the gel tips, and Bluetooth 5.3. Most competitors at this level publish two of those. The problem is not what Raycon offers. It is what the listing says about water.
The water rating contradicts itself inside one bullet
The product title says IPX7. The first bullet repeats “IPX7 Water resistance technology” and describes rain, sweat and whatever weather life throws at you. Then, in parentheses at the end of that same bullet, it says: “Disclaimer: Please do not submerge in water.”
IPX7 is an immersion rating. Its entire definition is submersion in fresh water at roughly one meter for about thirty minutes. A product that carries IPX7 and is then explicitly disclaimed against submersion is publishing two statements that cancel each other out. Either the code is not accurate, or the manufacturer does not stand behind it.
The specification table adds a third version, recording the water resistance level as “Water Resistant” with no code at all. And the recommended uses field lists “Water” as a use case, which sits oddly against a do not submerge disclaimer.
Read the disclaimer as the operative statement, because it is the one Raycon chose to add. Treat these as sweat and rain resistant, do not submerge them, and do not buy them for swimming. As always, no IP rating covers seawater or high pressure water in any case, and the protection degrades as seals and port covers age.
Battery: 56 hours, and no figure for a single charge
Raycon quotes 56 hours of battery total in the charging capsule. The specification table repeats 56 hours as the battery life. Nowhere on the page does the listing state how long the earbuds themselves run before they need the case.
That is the number that decides whether a pair works for your day, and its absence matters more here than on a product without cancellation. Active noise cancellation draws power continuously, so a cancelling earbud runs meaningfully shorter with it engaged than with it off, and neither figure is published. A 56 hour total in this class typically implies somewhere between 6 and 9 hours from the buds across five or six case refills, but that is arithmetic and not a specification, so ask before you buy if it matters.
Separating the two figures is the single most useful habit when shopping earbuds. Bud runtime is a listening session. Total with case is a week of commuting. They are not interchangeable and the marketing number is almost always the second one.
Noise cancellation, awareness mode and what they are each for
The specification field confirms active noise cancellation, and the third bullet describes both ANC and an awareness mode. Raycon publishes no decibel reduction figure and names no test standard, so there is nothing here to verify.
What applies generally applies here. Cancellation works well against constant low frequency noise: gym ventilation, treadmill motors, traffic rumble, cabin drone. It works poorly against speech and sudden sounds, which is why a busy gym floor stays audible while the air conditioning disappears. No earbud makes an environment silent.
Awareness mode is the more interesting feature on a fitness product. It uses the external microphones to pipe ambient sound back into the ear, which partially restores what the seal removed. That is genuinely useful for hearing a training partner or a gym announcement. It is not the same thing as an open ear design, because the canal is still sealed and the passthrough is processed and delayed. With cancellation engaged, these should not be used near traffic at all, and even in awareness mode a sealed bud is a compromise compared with a design that leaves the ear open. If your training happens on roads, the products in our open ear headphone reviews are the format built for it.
Multipoint, and what it actually gets you
Raycon states that both earbuds work independently or together and that up to two devices can be connected at the same time. Multipoint is the feature that stops your earbuds being stuck on a laptop while your phone rings, and at this price it is rarely published. It is a real reason to choose this over a cheaper pair.
Fit, missing specifications and the alternatives
Raycon says the box includes four additional gel tips plus ear stabilizers. Four tips could mean two extra pairs or four extra pairs depending on how you read it, and the listing does not clarify. Seal is what decides how much bass a sealed earbud produces and how well cancellation performs, so the ambiguity is worth resolving before ordering, particularly for smaller ear canals. The stabilizers are the more important part for training: a wing or fin that braces against the ear ridge stops a bud working loose during hard movement.
No Bluetooth audio codec is named anywhere. SBC, the baseline every Bluetooth device supports, is all you can assume. There is no published evidence of AAC, which is what Apple devices use, and none of aptX or LDAC, which only work when the phone and the earbuds both support the same one. No driver size, frequency response or sensitivity figure appears either, though impedance is given as 16 ohms. The specification table also lists a “3.5 mm Jack” and a “Cartoon Character” field containing the words “Fitness Earbuds,” both import noise.
Within Raycon’s own range the Impact Earbuds and the Everyday Earbuds 2024 Edition cover different use cases, and the model codes matter more than the names. For training earbuds from other brands with published bud runtimes, the JBL Endurance Peak 3 and the Soundcore Sport X20 are the ones to weigh. The wider set sits in our earbud headphone reviews.
Buy it, or skip it
Buy the Fitness Earbuds if you want a genuinely well specified feature set for training: cancellation, awareness mode, multipoint, single bud use, ear stabilizers and a 56 hour case total. Skip them if you need a water rating you can trust, because the listing claims an immersion code and then disclaims submersion in the same sentence. Skip them too if you need to know the bud runtime, the codec or the exact tip count before committing, because none of the three is published.
