If you want a wired, ear-hook design with an included microphone, choose HJX QKZ AK6; if you need tiny wireless earbuds for discreet listening, choose GUATTIR Mini Invisible Earbuds. For swimming, neither product’s listed features establish that it is designed for use in water, so I would not choose either specifically for swimming.
• HJX QKZ AK6 strength: An over-ear hook shape, three silicone tip sizes, a 3.5 mm wired connection, and an inline microphone suit listeners who want a straightforward cable-based setup. Trade-off: It is wired and lacks the tiny, discreet profile of the GUATTIR.
• GUATTIR Mini Invisible Earbuds strength: A compact wireless design, touch controls, a charging case, and up to 30 hours of total playtime support portable, low-profile listening. Trade-off: A single charge is listed as 5–6 hours, and the sheet does not describe a wired connection.
• Choose HJX QKZ AK6 if you prefer an ear hook, adjustable silicone tips, and a 3.5 mm plug.
• Choose GUATTIR Mini Invisible Earbuds if small, discreet Bluetooth earbuds and case-based charging matter more.
• For swimming: Neither sheet specifies water resistance, so these are not products I would select on the strength of a swimming use case.
• The difference is not simply wired versus wireless. These products are built around distinct priorities. HJX QKZ AK6 has a hook-style fit and a cable connection; GUATTIR Mini Invisible Earbuds focus on compactness, Bluetooth convenience, and a charging case. Neither product sheet provides a water-resistance rating or says the earbuds are made for swimming. That matters more than calling either one a sports or swimming pick.
The HJX QKZ AK6 is an in-ear wired model with an ear-hook shape. Its design wraps around the outside of the ear, while the earbud sits just inside. Three included silicone tip sizes—small, medium, and large—give you options for finding a fit that feels secure. That combination will appeal to someone who prefers an earbud supported by the outer ear rather than one held only by the tip.
Its 3.5 mm jack makes it a fit for a compatible wired audio source. There is no Bluetooth connection listed, so you do not need to plan around wireless pairing or charging, but you do need a device with a compatible jack. An inline microphone and button controls add practical functions for calls and basic control. The 11 mm dynamic driver and listed 20 Hz–20,000 Hz frequency range describe the audio hardware; they do not, on their own, establish how it will sound to every listener.

The product information lists hybrid noise cancellation, while the design is still a wired in-ear earbud rather than a compact sleep-focused model. I would look closely at whether its hook shape and cable suit your routine before choosing it for long wear. The sheet also lists a 30-millisecond audio latency, but it does not state the conditions used for that figure.
Who should skip it: Skip the HJX if you need Bluetooth, a nearly invisible earbud, or a product with stated suitability for swimming.
The GUATTIR Mini Invisible Earbuds are designed around a small, discreet wireless form. The product information describes them as especially suited to small ear canals and extended wear, including work and sleep. That makes their compact profile the main reason to consider them over the HJX. If you want earbuds that draw less attention than a hook-and-cable design, this is the more relevant option of the two.
Bluetooth 5.3 provides the listed wireless connection, and the product sheet gives a Bluetooth range of 10 meters. The earbuds are described as reconnecting when the charging case opens, with touch controls for playback, volume, and calls. Those features may simplify everyday handling: take them from the case, connect to a paired device, and use taps instead of searching for a button. The sheet also lists a built-in microphone with noise reduction and echo cancellation, though those terms are not a guarantee of call quality in every setting.
Battery life is a clear trade-off to understand. GUATTIR lists 5–6 hours of continuous use per charge and up to 30 hours total with the 300 mAh case. The case extends use between charging sessions, but it does not mean the earbuds themselves run for 30 hours continuously. The listed charging time is 1.5 hours. The earbuds use sound isolation; that is not the same as a stated active noise-cancellation feature. Nor does the sheet give a water-resistance rating.
Who should skip it: Skip the GUATTIR if you specifically want a 3.5 mm wired connection, an ear hook, or confirmed suitability for swimming.
• Best fit for a 3.5 mm audio source → HJX QKZ AK6. Its wired connection is explicit, but your device needs a compatible jack. - Best for a discreet wireless profile → GUATTIR Mini Invisible Earbuds. Their compact design and Bluetooth connection fit buyers who want to avoid a visible hook and cable. - Best for choosing among included ear-tip sizes → HJX QKZ AK6. It comes with small, medium, and large silicone tips. - Best for a listening setup without Bluetooth pairing → HJX QKZ AK6. Its wired connection avoids the need for wireless pairing, though it still requires a compatible source. - Best for touch-operated wireless controls → GUATTIR Mini Invisible Earbuds. The listed touch controls cover playback, volume, and calls. - Best for swimming → Neither. Neither product’s information specifies water resistance or swimming use. - Best for buyers prioritizing a hook-style design → HJX QKZ AK6. The GUATTIR is instead described as a small, discreet earbud.
Searches for the best sports earbuds for swimming often combine two separate requirements: a secure fit during movement and suitability for water. The HJX’s ear hook may appeal to someone who likes that style of support, but the listed features do not establish that it can be used in a pool. The GUATTIR’s small profile and wireless connection likewise do not establish water protection.
The same caution applies to searches for the best noise cancelling sleep headphones for swimming or the best comfortable Bluetooth headphones for swimming. GUATTIR is the Bluetooth choice and is described for sleep and discreet wear, but its stated noise control is sound isolation, not a documented swimming feature. HJX lists hybrid noise cancellation, but it is wired and has no stated water-resistance information. For actual swimming, I would first look for a product whose specifications explicitly identify water use.
Start with the connection your device supports. HJX QKZ AK6 uses a 3.5 mm jack, so it makes sense if you have a compatible audio source and want to avoid Bluetooth. GUATTIR connects wirelessly using Bluetooth 5.3 and lists a 10-meter range. The choice is practical, not just aesthetic: a wired setup means a cable, while wireless listening means pairing and keeping the earbuds charged.
Next, consider how you want the earbuds to sit. HJX uses a hook that wraps around the outer ear and includes three silicone tip sizes. GUATTIR emphasizes a small, discreet shape intended for small ear canals and long wear.
Think carefully about what “noise cancelling” means in this comparison. HJX’s information lists hybrid noise cancellation. GUATTIR lists sound isolation and describes noise reduction and echo cancellation for its microphone. These are not interchangeable claims: the GUATTIR’s call processing does not establish active noise cancellation for listening, and its sound isolation does not make it a swimming earbud.
Battery expectations also separate the picks. HJX is wired, so its listed features do not include an earbud battery-life figure. GUATTIR lists 5–6 hours on one charge, with up to 30 hours when the charging case is included. If you often listen for long stretches, distinguish the continuous-use figure from total playtime across case recharges.
Most important for anyone shopping around water: neither product sheet lists a water-resistance rating. An ear hook, compact body, sound isolation, or Bluetooth connection is not proof of protection from water. If swimming is the real priority, I would keep looking rather than infer suitability from these designs.
In my opinion, I would choose GUATTIR Mini Invisible Earbuds for ordinary wireless listening because their compact design, touch controls, and charging case make a more convenient combination for discreet use. I would choose HJX instead if I specifically wanted a wired 3.5 mm connection and an ear hook.
For swimming, though, I would buy neither based on the information provided. Neither sheet identifies water resistance or swimming use, and that is the key requirement I would want confirmed before choosing earbuds for a pool.
FAQ
Neither product’s listed information specifies water resistance or says it is made for swimming. I would not treat either as a swimming option without explicit confirmation of water suitability.
GUATTIR is described as a small, discreet option for small ear canals. HJX includes small, medium, and large silicone tips, which may help you adjust the fit, but the sheet does not specifically describe it as a small-ear-canal model.
The GUATTIR information lists sound isolation and describes noise reduction and echo cancellation for calls. It does not establish active noise cancellation for listening. HJX lists hybrid noise cancellation, but the available details do not explain its operation.
HJX is wired and has no earbud battery-life figure listed. GUATTIR is listed for 5–6 hours of continuous use per charge and up to 30 hours total with its charging case, so the larger figure includes case-supported recharging.
