If you want a two-in-one adapter for connecting 3.5 mm headphones while charging a compatible Samsung phone, choose HopePow 2; if you need a 3.3-foot USB-to-USB-C charging cable, choose PROTEAR USB C Cable. For cycling, the choice comes down to the connection you need: HopePow 2 combines headphone and charging connections, while PROTEAR is a straightforward cable for charging.
HopePow 2 vs PROTEAR USB C Cable at a Glance
• PROTEAR USB C Cable’s biggest strength: its 3.3-foot USB-to-USB-C format can connect compatible devices to a USB port, power adapter, power bank, or car charger; trade-off: it is a charging cable, not a headphone adapter.
• Choose HopePow 2 if you have a compatible Samsung phone and want to use wired 3.5 mm headphones while charging.
• Choose PROTEAR if you need a separate USB-C charging cable, particularly for PROTEAR rechargeable headphones or other compatible Type-C devices.
HopePow 2 is an adapter cable for a particular problem: a compatible Samsung phone has a USB Type-C connection, but you want to connect headphones with a 3.5 mm plug and charge the phone at the same time. Its two-in-one design brings those functions together, rather than asking you to choose between listening through wired headphones and using the charging connection.
That combination may be useful when setting up for a bike ride. If your phone is your music source and your wired headphones use a 3.5 mm plug, the adapter is designed to accommodate listening and charging together. The listing identifies several Samsung Galaxy models, including S26, S25, S24, A17, A57, A37, A27, and A16 variants. Check the exact phone model and your headphone connector before choosing it; the product is not described as a universal adapter for every USB-C device.
The cable is black with a nylon finish, and its listed item weight is 5 grams. Those details point to a lightweight accessory rather than a bulky charging unit. Still, the information provided does not specify the cable’s length, charging speed, or audio controls. I would not assume particular performance or control features from the two-in-one design alone. Skip HopePow 2 if you need a USB-C charging cable for a headset or device, or if your headphones do not have a 3.5 mm plug.
PROTEAR is the more focused option: a USB male-to-USB-C cable for charging. It is 3.3 feet, or 100 centimeters, long. That gives you a defined length to work with when connecting to a power adapter, computer USB port, power bank, or car charger. The listed uses make it a practical replacement cable to keep with a compatible device, rather than a combined audio-and-charging adapter.

The cable is designed for PROTEAR rechargeable headphones and is also described as compatible with a range of devices that use a Type-C port. The listed examples include certain iPhone 15 and 16 models, Samsung Galaxy S24 and S25 models, iPad Pro and Air, and MacBook Pro and Air. Compatibility wording can cover different models and configurations, so confirm the port on your particular device before buying. The key point is that this is for charging; the information does not describe a 3.5 mm audio connection.
For cycling, this cable can make sense as part of your charging routine before or after a ride, or as a replacement for a lost cable for compatible rechargeable headphones. Its 100-centimeter length offers a little reach without being an unusually long cable. The listed package includes one cable and a 12-month worry-free period. No specific charging wattage or data-transfer capability is provided, so I would treat it as a charging cable rather than assume additional functions. Skip PROTEAR if your main need is connecting 3.5 mm headphones to a phone while charging.
Side-by-Side: Which Should You Choose?
• Need a USB-C charging cable for PROTEAR rechargeable headphones → PROTEAR. It is specifically described as a replacement charging cable for those headphones.
• Want a cable with a stated length → PROTEAR. Its listed length is 3.3 feet, or 100 centimeters; HopePow 2’s cable length is not specified in the supplied details.
• Want a combined audio-and-charging connection → HopePow 2. PROTEAR is described as a USB-to-USB-C charging cable, with no headphone-jack function listed.
• Need a cable for a power bank, computer USB port, or car charger → PROTEAR. Those are listed charging sources for the cable.
• Looking for a lightweight accessory to carry with a compatible Samsung phone → HopePow 2 may fit. Its listed item weight is 5 grams, though the information does not provide a packed-use or storage description.
• Shopping for on-ear headphones for cycling → neither product is a headset. HopePow 2 is an adapter and PROTEAR is a charging cable; choose between them based on the connection or charging need you actually have.
• Searching for the best touch control kids headset for cycling or the best voice assistant in ear headphones for cycling → neither is a headphone. The supplied details do not list touch controls, a microphone, or voice-assistant features for either product.
First, identify what you are connecting. HopePow 2 is the pick when you need both a 3.5 mm headphone connection and charging through a compatible Samsung phone’s USB Type-C connection. PROTEAR is the pick when you need a separate cable to charge a USB-C device. They are not interchangeable just because both involve USB-C.
Next, check the ports on both ends. For HopePow 2, confirm that your Samsung model is among the listed compatible phones and that your headphones have a 3.5 mm plug. For PROTEAR, confirm that the device has a Type-C charging port and that the source you plan to use offers a USB port. A cable that fits the device is not automatically a match for every charging setup.
Finally, be precise about what the product descriptions do and do not establish. HopePow 2 is described as combining headphone and charging connections, but no specific charging rate or audio-control features are listed. PROTEAR is described as a charging cable, but no wattage or data-transfer function is specified. If those capabilities are essential to your setup, do not infer them from the connector type alone. For current price information, check the product page on Amazon.
My Verdict
For cycling, I would choose HopePow 2 if I needed to keep using 3.5 mm headphones while charging a compatible Samsung phone; its two-in-one purpose is the more distinctive fit for that setup. I would choose PROTEAR instead if my actual need were a clearly specified 100-centimeter charging cable for compatible USB-C headphones or another device. My recommendation is HopePow 2 for the combined listening-and-charging use case, not as a substitute for headphones or a general charging cable.
It is described as a two-in-one adapter for connecting 3.5 mm headphones and charging a compatible Samsung phone at the same time. The supplied details do not specify charging speed or particular audio-control functions.
No headphone-jack connection is listed for PROTEAR. It is a USB male-to-USB-C charging cable, described for PROTEAR rechargeable headphones and other compatible Type-C devices.
Its stated length is 3.3 feet, or 100 centimeters. It can connect a compatible device to a power adapter, computer USB port, power bank, car charger, or another suitable USB port.
Choose HopePow 2 if you need a 3.5 mm headphone connection and simultaneous charging on a compatible Samsung phone. Choose PROTEAR if your headset has a USB-C charging port and you need a separate charging cable; neither product is itself a headset.
