If you want a spare magnetic charger for compatible bone-conduction headphones for the gym, choose Xininyia 2-Pack; if you need to charge a USB-C device while connecting wired headphones, choose Meliya USB C. These are different kinds of accessories, so the practical choice comes down to what you need to connect, not which one does the same job better.
For a gym bag built around compatible open-ear headphones, Xininyia offers two dedicated charging cables. Meliya instead combines USB-C charging with a 3.5 mm audio connection, making it the more relevant option for someone who wants those two connections together.
• Xininyia 2-Pack’s biggest strength: Two magnetic charging cables for specified compatible bone-conduction headphone models; its trade-off is that it is not a general-purpose USB-C audio adapter.
• Meliya USB C’s biggest strength: A 2-in-1 adapter with USB-C, a 3.5 mm headphone jack, and a PD charging port described as supporting up to 60W; its trade-off is that it is not a magnetic charger for the named bone-conduction headphone models.
• Xininyia is for: Owners of compatible headphones who want a second charging cable or a cable to keep in another bag.
• Meliya is for: People who need to connect wired 3.5 mm headphones while charging a USB-C device.
• The key distinction: Xininyia is a dedicated headphone charger; Meliya is an audio-and-charging adapter.
Xininyia makes the more focused choice if you own bone-conduction headphones that use its compatible four-pin magnetic charging connection. The listed compatible models include SAMVEK X7, Dnniakm X7 Pro, Haowolf X16, Hitarah X19, and POLVCDG Series headphones. The package contains two magnetic chargers, each with a 60 cm cable. That gives you a practical way to keep one cable with your gym gear and another where you usually charge your headphones.
The magnetic connection, short-circuit protection, and stated over-voltage and over-current protections are useful design details for a dedicated charging cable. Xininyia also describes the cable as made from ABS and flexible PVC and says it has been tested through more than 5,000 bending cycles. Those specifications point to portability and a cable intended for repeated handling. They do not make it a universal charger, though: compatibility with the listed headphone connection is the deciding factor.
I would consider Xininyia if your headphones match the supported models and you want a spare for travel, a locker bag, or a second charging spot. I would skip it if you need to connect standard wired headphones to a phone or laptop, or if your headphones use a different charging connector. It has a USB Type-A connector, so it is not the USB-C-to-3.5 mm solution offered by Meliya. For an open-ear headphones for gym setup, Xininyia makes sense only when your particular headphones are among the compatible types.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Meliya USB C: Who It's For
Meliya combines two connections in one adapter: a 3.5 mm audio jack for wired headphones and a USB-C port for charging. Its description identifies the charging connection as a PD port supporting up to 60W. In practical terms, the design is aimed at someone who wants to listen through wired headphones and connect a charger at the same time, rather than choosing between audio and charging access.
The listed connection types are USB-C and a 3.5 mm audio jack, and the product information identifies laptops among its compatible devices. That does not establish compatibility with every phone, laptop, headphone, or charger, so it is worth checking that the device you plan to use supports the necessary connections. Meliya is also described as a single adapter, not a pair of separate charging cables.
I would choose it for a USB-C device and wired headphones with a 3.5 mm plug, especially if simultaneous audio and charging are the main needs. I would skip it if you are looking specifically for a magnetic charging cable for compatible bone-conduction headphones. It is not the natural pick for someone searching for wireless earbuds for gym use, because the listed audio connection is for wired headphones and the product information does not describe earbuds or wireless audio features. It also does not replace Xininyia’s two-cable arrangement for the specified headphone models.
• Best for charging the listed compatible bone-conduction headphones: Xininyia 2-Pack. Its magnetic four-pin chargers are designed for the named headphone models and series.
• Best for carrying a spare dedicated headphone charger: Xininyia 2-Pack. The package includes two 60 cm magnetic charging cables.
• Best for wired headphones with a 3.5 mm plug: Meliya USB C. It provides a 3.5 mm audio jack as part of its 2-in-1 design.
• Best for charging while using wired audio: Meliya USB C. Its design pairs the audio connection with a USB-C charging port described as supporting PD up to 60W.
• Best fit for a gym bag with compatible magnetic-charging headphones: Xininyia 2-Pack. One cable can be kept with gym gear while the other stays at home or at work.
• Best fit for a USB-C device and wired listening: Meliya USB C. It is the more direct match when both charging and a 3.5 mm headphone connection matter.
• Best choice for someone comparing a gaming headset for gym use: Neither product should be treated as a gaming headset. Choose Xininyia only for charging compatible bone-conduction headphones; choose Meliya only if you need its USB-C charging and wired-audio connections.
• Best choice when headphone compatibility is uncertain: Check the connector and supported-device details before choosing. Xininyia depends on a matching magnetic connection; Meliya depends on the USB-C device and 3.5 mm headphones fitting your setup.
For a gym setup built around one of the compatible bone-conduction models, I would buy Xininyia 2-Pack because it supplies two dedicated magnetic charging cables. That is the clearer fit when charging those headphones is the whole job.
I would choose Meliya instead if my priority were listening through 3.5 mm wired headphones while charging a USB-C device. For gym use, my pick is Xininyia when the headphone connection matches; Meliya solves a different problem.
No. The listed connector for Xininyia is USB Type-A, and the cables use a magnetic charging connection for specified compatible bone-conduction headphones. It is not the USB-C audio-and-charging adapter in this comparison.
Its design includes a USB-C charging port and a 3.5 mm headphone jack, so it is intended to provide charging and wired audio connections together. The charging port is described as supporting PD up to 60W; check compatibility with your specific device and accessories.
Neither listing describes a general-purpose wireless-earbud charging solution. Xininyia is for compatible bone-conduction headphones with its magnetic connector, while Meliya provides a 3.5 mm audio jack and USB-C charging connection.
Xininyia includes two charging cables, so it is the more straightforward spare-cable option if your headphones are compatible. Meliya is a single adapter intended to combine USB-C charging with wired headphone audio, rather than provide two dedicated charging cables.
