If you want wireless freedom, long listening between charges, and a fit you can adjust, choose Aoslen Earbuds; if you need a simple wired USB-C connection, choose MAS CARNEY USB C Headphones. For a big head, though, neither product is an over-ear design, so neither can promise the headband space that usually matters in a search for headphones that fit generously.
My pick for most people choosing between these two is Aoslen: it offers more flexibility for workouts and moving around, plus multiple ear-tip sizes. Choose MAS CARNEY only if a direct USB-C connection is your priority and your device is compatible.
• Aoslen’s biggest strength: Bluetooth 5.3, touch controls, a charging case with an LED battery display, and up to 6–7 hours of listening per charge. Trade-off: it sits in the ear, not over it, and needs charging.
• MAS CARNEY’s biggest strength: a straightforward wired USB-C connection with an in-line remote and microphone. Trade-off: it needs a compatible USB-C port and a cable connecting you to your device.
• For movement and listening away from your phone: Aoslen is the more flexible fit, with a stated wireless range of up to 15 meters.
• For plug-in listening with no Bluetooth pairing: MAS CARNEY is the simpler choice, provided the phone’s USB-C port supports the headphones.
• Choose Aoslen if you want wireless earbuds, adjustable ear tips, and a charging case. Choose MAS CARNEY if you specifically want wired USB-C earbuds.
Aoslen is the better match for someone who wants to listen while moving around without a cable running to a phone. It uses Bluetooth 5.3, pairs automatically with the last paired device, and has touch controls for functions such as music playback, calls, volume, track changes, and a voice assistant. The listed wireless range is up to 15 meters, which can be useful when your phone is nearby but not in your hand.

The battery setup is a clear part of its appeal: the earbuds are listed for 6–7 hours of music, and the case is described as providing an additional 42 hours of playback. An LED display shows the charge level of the earbuds and case. Aoslen also includes three ear-tip sizes, which gives you more options for finding a secure in-ear fit. That matters more to me than a vague promise of comfort: a choice of sizes lets the buyer adjust the fit rather than relying on one fixed tip.
There are four built-in microphones, and the product describes ENC noise reduction for calls. It also lists an IP7 waterproof rating and positions the earbuds for activities such as running and training. I would choose Aoslen for wireless convenience and exercise use, not for a big-head fit in the over-ear sense. If your main goal is a roomy headband or cushions that sit around the ears, these in-ear earbuds are the wrong shape. They are also not the pick for someone who wants to avoid charging.
MAS CARNEY is for someone who wants a wired earbud connection through USB-C rather than a wireless pairing process. Its remote control and microphone are part of the cable setup, and its rounded-tip earbuds use sound isolation. For a desk, commute, or call where you want to plug into a compatible phone and keep listening, the wired design may be exactly the point.
Compatibility is the main thing to check. These headphones need an active USB-C port; a device with only a 3.5 mm headphone jack is not compatible. The phone case must also leave the USB-C port accessible, and the plug needs to be fully seated. Those requirements are not minor details: if the port is blocked or the device is incompatible, this is not a useful fallback headphone.
The product information lists a dynamic driver and a 20–20,000 Hz frequency range, but that does not establish how it will sound to an individual listener. It is an in-ear model, not an over-ear headset, and the supplied details do not give ear-tip size options or a battery figure. I would consider it for a buyer who values a direct wired USB-C connection, but skip it if you want wireless movement, a disclosed multi-size tip selection, or headphones designed around a larger head.
• Best for wireless listening → Aoslen Earbuds. Bluetooth 5.3 means no cable to the phone, and the stated range is up to 15 meters.
• Best for a wired USB-C setup → MAS CARNEY USB C Headphones. Pick it if you prefer a physical connection and have a compatible, accessible port.
• Best for extended listening between charges → Aoslen Earbuds. The earbuds are listed for 6–7 hours per charge, with the case offering additional playback.
• Best for avoiding Bluetooth pairing → MAS CARNEY USB C Headphones. It connects by cable, though device compatibility is essential.
• Best for choosing an ear-tip size → Aoslen Earbuds. Three sizes are included; the MAS CARNEY details do not specify multiple tip sizes.
• Best for exercise use based on stated features → Aoslen Earbuds. The product lists IP7 waterproofing and describes use for running and training.
• Best for an in-line remote → MAS CARNEY USB C Headphones. Its control method is listed as a remote; Aoslen uses touch controls on the earbuds.
• Best for a big head → Neither as a true over-ear option. Both are in-ear models, so neither has a headband whose fit can be assessed for head circumference. If you mean an in-ear fit rather than headband size, Aoslen at least includes three tip sizes.
I would buy Aoslen Earbuds if I were choosing between these two: wireless use, touch controls, a battery display, and three ear-tip sizes make it the more versatile option for everyday movement.
For a big head, I would still treat that as an in-ear choice, not a substitute for over-ear headphones. If I wanted a wired USB-C connection and had a compatible phone, I would choose MAS CARNEY instead.
Neither is an over-ear headphone; both are in-ear designs, so neither provides a headband fit for a large head. Aoslen includes three ear-tip sizes, which offers more adjustment for ear fit.
MAS CARNEY uses a wired USB-C connection, so it does not require Bluetooth pairing. The device needs a compatible USB-C port, and its case must not block that port.
The product lists active noise control and describes four microphones with ENC noise reduction for calls. That information is not the same as a stated over-ear noise-cancellation system; Aoslen remains an in-ear product.
Aoslen is the more clearly suited option based on the listed features: it is wireless, includes multiple ear-tip sizes, and is described for running and training with an IP7 waterproof rating. MAS CARNEY is wired and requires a USB-C connection to the device.
