If you want a hard protective case for compatible Beyerdynamic studio headphones, choose Mchoi Hard; if you need a portable CD player with Bluetooth output, choose SKYANS CD Player. For a MacBook setup, these solve different problems: Mchoi stores and protects headphones, while SKYANS plays CDs and can send their audio to Bluetooth headphones or speakers.
Mchoi Hard vs SKYANS CD Player at a Glance
• SKYANS CD Player’s strength: It plays several CD formats, supports USB playback, and can transmit CD audio to Bluetooth headphones or speakers. Trade-off: Its Bluetooth works as an output, not as a receiver for a MacBook or phone.
• Choose Mchoi Hard if your Beyerdynamic DT 990 PRO or DT 770 PRO needs a dedicated case for storage and travel.
• Choose SKYANS CD Player if you want portable CD playback with built-in speakers, wired connections, and Bluetooth transmission.
Mchoi Hard is a protective carrying case made to fit Beyerdynamic DT 990 PRO and DT 770 PRO open studio headphones. Its hard EVA exterior is intended to help shield the headphones from knocks, bumps, and pressure during storage or transport. Inside, a soft Lycra lining adds a gentler contact surface than the outer shell, while a built-in mesh pocket gives you a place for accessories.
That layout makes sense for someone who moves between a desk, a studio, and another listening spot, or who wants to put headphones away without leaving them exposed. The reinforced handle makes the case easier to carry by hand. The product description also notes a hand strap that can be hung from a backpack, a useful detail for someone carrying several items. Its listed dimensions are 9 by 6.8 by 4.3 inches, and the compatible-device size is listed as up to 4.3 inches. Those figures help set expectations about the case, but the stated compatibility with the named Beyerdynamic models is the more important fit check.
This is not a pair of headphones, a MacBook accessory that plays sound, or a general-purpose audio product. It is an empty protective case, and the headphones and accessories are not included. The listed portable water-resistance detail should not be read as a reason to expose the case or its contents to water; the supplied information does not describe a waterproof rating or water-use conditions.

Who should skip this: Skip Mchoi Hard if you need headphones, a CD player, or a case for a model other than the stated compatible Beyerdynamic headphones.
SKYANS is the more active audio device of the two. It plays CD, CD-R, and CD-RW discs, along with MP3 and WMA files, and it also supports playback from a USB flash drive. The built-in speakers allow listening without connecting separate headphones or speakers. For private listening, there is a 3.5mm headphone jack; the same 3.5mm connection can also be used with an AUX cable to connect to external speakers or a car system.
Its rechargeable 2000mAh battery is designed to make the player usable away from a wall outlet, including during travel or other outings. The information provided does not state a runtime, so I would not assume a particular number of hours between charges. It also lists a Type-C cable as included. The player has buttons for common actions such as skipping tracks and pausing, as well as repeat options: one-song loop, whole-disc loop, and random playback. Those modes are handy if you want to replay a track or let a disc play in a less predictable order.
Bluetooth 5.3 lets SKYANS transmit audio to Bluetooth headphones or speakers. That could be useful if you want to listen to a CD through wireless headphones while working near your MacBook, but it does not make SKYANS a wireless audio source for the computer. The player does not receive Bluetooth from phones, tablets, or similar devices. For MacBook use, that distinction matters: SKYANS can send its own CD audio outward, but it is not described as a device that connects to a MacBook to play the computer’s audio.
The product is listed as 280 g and comes in pink. Its LCD screen provides a display, while the side switch can lock the controls in HOLD mode; if buttons seem unresponsive, the supplied guidance is to check that switch and set it to ON. This is a compact collection of playback options, but it is still a CD player rather than a dedicated set of headphones. Its value depends on having discs or files you want to play and being comfortable with its wired or Bluetooth-output setup.
Who should skip this: Skip SKYANS if you need a protective case for Beyerdynamic headphones or want Bluetooth headphones to receive audio from your MacBook.
• Best for protecting compatible Beyerdynamic headphones → Mchoi Hard. Its hard EVA shell, soft lining, and mesh pocket are purpose-built for carrying and storing the named DT 990 PRO and DT 770 PRO models.
• Best for playing CDs on the go → SKYANS CD Player. It supports CD, CD-R, and CD-RW discs, plus MP3 and WMA playback.

• Best for wireless CD listening → SKYANS CD Player. It can transmit CD audio to Bluetooth headphones or speakers, but does not receive Bluetooth audio.
• Best for listening without separate speakers → SKYANS CD Player. It has built-in speakers, a headphone jack, and support for external speakers through AUX.
• Best for repeat and random playback choices → SKYANS CD Player. Its playback modes include single-track repeat, whole-disc repeat, and shuffle-style random playback.
• Best for straightforward headphone transport → Mchoi Hard. Its reinforced handle is designed to make the case easier to carry.
• Best for a MacBook desk where you want to store headphones → Mchoi Hard, if your headphones are compatible. SKYANS is a separate CD source, not a Bluetooth receiver for MacBook audio.
Buying Considerations
Before choosing SKYANS, consider what you want to connect and which direction the audio needs to travel. Its Bluetooth is for sending sound from the CD player to Bluetooth headphones or speakers. It is not for receiving music from a MacBook, phone, or tablet. If your aim is simply to use Bluetooth headphones with a MacBook, this player does not fill that role based on the listed features. It is a better fit when the source is a CD or supported file on a USB flash drive.
Battery claims also need a careful reading. SKYANS has a built-in 2000mAh rechargeable battery, but no battery-life duration is provided. That makes it a portable option in design, not a basis for promising long listening sessions. Someone searching for long battery life Bluetooth headphones for MacBook should note that SKYANS is a CD player with Bluetooth transmission, not a set of headphones, and the supplied details do not specify runtime.
Likewise, a search for the best IPX7 waterproof headset for MacBook points toward a category neither product represents. Mchoi is a case, and the available water-resistance wording does not establish an IPX7 rating. SKYANS is a portable CD player, not a waterproof headset. For buyers comparing these two, the practical decision is not about headset waterproofing: it is whether you need headphone storage or a portable CD playback source.
I would choose Mchoi Hard if my priority were protecting compatible Beyerdynamic headphones in a home, studio, or travel bag. It has a clear job and includes a hard shell, soft lining, mesh pocket, and carrying handle. For a MacBook setup, I would pick it as a storage solution—not as an audio device. I would choose SKYANS instead only if I specifically wanted a portable CD player with built-in speakers and Bluetooth audio transmission.
No. Its Bluetooth feature transmits audio from the CD player to Bluetooth headphones or speakers; it does not receive Bluetooth audio from a MacBook. The listed wired options are a 3.5mm AUX connection and USB playback from a flash drive.
Is Mchoi Hard a headphone case for any headphones?
It has a built-in 2000mAh rechargeable battery, but no specific runtime is given. That confirms it is rechargeable and designed for portable use, not how many hours it will play between charges.
Neither product is a pair of headphones. Mchoi Hard stores compatible Beyerdynamic headphones, while SKYANS plays CDs and can transmit its own audio to Bluetooth headphones or speakers. If you already own compatible headphones, choose Mchoi for a case; choose SKYANS only if you also want its CD playback functions.
