If you want lightweight, collapsible wired headphones for your MacBook, choose Koss UR40; if you need a protective sleep-mode case for AirPods Max used with your MacBook, choose Yinke Case. These are different kinds of products: the UR40 is a listening device, while Yinke is a carrying case for compatible Apple headphones.
• Koss UR40: Over-ear headphones with a 3.5 mm wired connection, a collapsible design, and a breathable mesh headband. The trade-off is that they are wired and do not provide a listed volume limiter or wireless multipoint connection.
• Yinke Case: A hard EVA case with a handle, protective lining, and support for AirPods Max sleep mode. The trade-off is that it is a case, not a pair of headphones, and it is made for AirPods Max rather than the UR40.
• Choose Koss UR40 if you need headphones to connect to a MacBook and listen through a wired connection.
• Choose Yinke Case if you already own compatible AirPods Max and want storage and protection while traveling.
The Koss UR40 is the actual headphone in this comparison. Its over-ear design, dynamic drivers, and 3.5 mm jack make it a straightforward option for listening from a MacBook that has a compatible headphone connection. The listed impedance is 60 ohms, and the stated frequency range varies across the product information: it gives a 10–20,000 Hz range in one place and describes a 15–22,000 Hz response elsewhere. Those figures describe the range the headphones are designed to reproduce; they do not, on their own, establish how a particular listener will judge the sound.
For everyday use, the practical draw is the combination of a wired connection and a collapsible frame. A cable means you do not need to manage headphone battery life or a Bluetooth connection, while the folding design makes the headphones easier to pack than a fixed, non-collapsible frame. Koss also lists a lightweight build, a breathable mesh headband, and memory-foam cushions. Those features point toward a design intended for longer listening sessions, whether that means working through audio at a desk or listening while traveling.

The ear cups are described as screened, with an open, hear-through character. That may suit someone who wants to remain more aware of nearby sounds, but it is not the feature I would choose for blocking out a noisy room. The UR40 is also not described as having a volume-limiting function, so it is not a good match if a built-in maximum-volume cap is essential. Who should skip it: skip the UR40 if you specifically need Bluetooth multipoint, a stated volume limiter, or a case for AirPods Max.
Yinke Case is not a competing headphone model. It is a hard travel case designed for AirPods Max, with the product information identifying compatibility with AirPods Max 1 and 2. Its central feature is sleep-mode support: the case is intended to allow compatible AirPods Max to enter a low-power state while stored. That makes it relevant to a MacBook owner who already has AirPods Max and wants a more protective way to carry them between home, work, or travel.
The case uses an EVA hard shell, with velvet or fleece lining and a point-patterned shock-absorbing interior described in the product details. Its stated protective features include resistance to bumps, scratches, and water. It also has a handle and a double-zipper design, which gives it a practical role as a dedicated storage and carrying solution rather than a simple soft cover. The product information lists external dimensions of 23.5 × 21.0 × 6.3 cm, so shoppers can compare those measurements with the space they have in a bag.
The most important limitation is compatibility. The case is built around AirPods Max; it will not turn the Koss UR40 into a sleep-mode device or protect the UR40 as a purpose-made fit. Nor does it provide sound, a connection to a MacBook, or any headphone controls. Who should skip it: skip Yinke Case if you do not own compatible AirPods Max or if what you need is a new pair of headphones rather than storage.
• Best for listening directly from a MacBook → Koss UR40. It is the only product here that is a pair of headphones, and its 3.5 mm jack provides a wired connection.
• Best for AirPods Max storage → Yinke Case. It is designed for AirPods Max and is meant to protect and carry them.
• Best for avoiding headphone battery management → Koss UR40. Its wired design does not require you to keep the headphones charged for listening.
• Best for a MacBook setup that also needs a travel case → Yinke Case, if you own AirPods Max. The case has a hard shell, protective lining, and a carrying handle.
• Best for a compacting headphone frame → Koss UR40. Its collapsible design is useful when you want the headphones to take up less space in a bag.
• Best for sleep-mode storage → Yinke Case. The stated sleep-mode feature applies to compatible AirPods Max, not the Koss headphones.
• Best volume-limiting headphones for MacBook → neither is a clear match based on the listed features. The UR40 does not list a volume limiter, and Yinke is only a case.
• Best sleep headphones for MacBook → neither, if you mean headphones to wear while sleeping. Yinke’s sleep-mode support refers to the AirPods Max entering a low-power state inside the case.
• Best multipoint headphones for MacBook → neither based on the available specifications. The UR40 is wired, while Yinke does not provide a headphone connection or Bluetooth feature.
Buying Considerations
For MacBook use, check the connection you actually plan to use. The UR40 has a 3.5 mm jack, so it fits a wired setup where that connection is available. It does not offer the convenience of switching wirelessly between a MacBook and another device. If you searched for multipoint headphones for MacBook, note that no multipoint feature is specified for the UR40, and the Yinke case has no wireless audio function at all.
Think about your surroundings, too. The UR40’s screened ear cups are described as allowing more awareness of sounds around you. That can be useful if you want to hear some of what is happening nearby, but it is not the same as a stated noise-cancelling system. And if your priority is controlling maximum listening volume, the product information does not list a volume-limiting feature.
For travel, the needs split neatly. The UR40’s collapsible design and lightweight construction are relevant if you want headphones that pack down for a trip. Yinke’s hard shell and handle are relevant if you carry AirPods Max and want a dedicated protective container. Before choosing the case, confirm that your headphones are AirPods Max and compare its listed dimensions with your available bag space.
I would choose the Koss UR40 if I wanted a simple wired listening option for a MacBook: it is the only one of these two that actually plays audio, and its collapsible, lightweight design makes sense for carrying around. I’d choose Yinke Case only if I already owned compatible AirPods Max and wanted added storage and protection. For my MacBook setup, I’d buy the UR40, while keeping in mind that it does not claim multipoint or volume-limiting features.
The Yinke case is described as being made for AirPods Max, including the first and second generations. The product information does not identify the Koss UR40 as a compatible headphone, so I would not choose it as a UR40 case.
The Koss UR40 has a wired 3.5 mm headphone jack, making it the listening product in this comparison. Yinke Case is a storage case and does not connect to a MacBook or play audio.
Neither feature is listed for the UR40. Its listed connection is wired, and the available product details do not specify a built-in maximum-volume limiter or multipoint Bluetooth.
No. The sleep-mode feature is described as helping compatible AirPods Max enter a low-power state while inside the case. It does not mean the case is worn or used for listening during sleep.
