For Sony WH-CH720N headphones, the Skullcandy Hesh 3 is my pick for a headphone case alternative: its collapsible over-ear design is the strongest fit for carrying headphones. Sony is the runner-up if you want a dedicated 3.5 mm headphone socket for personal listening.
headphones case for sony wh ch720n at a Glance
• Skullcandy Hesh 3 — best for carrying over-ear headphones in a compactable design; pick this if Bluetooth listening, noise-isolating fit, and foldability matter.
• Sony ICF-506 — best for portable AM/FM radio listening; pick this if you want analog tuning and a dedicated headphone socket.
• Kinboofi KZ ZS10 — best for wired in-ear monitoring; pick this if a detachable cable and 3.5 mm connection suit your listening setup.
The Skullcandy Hesh 3 is the most relevant choice here for someone searching for a headphones case for Sony WH-CH720N, but it is important to be clear about what it is: a pair of wireless over-ear headphones, not a storage case. Its connection to the search is practical rather than literal. Among these four products, it is the one designed to sit over the ears and collapse for easier carrying.
The collapsible design is useful if you want headphones that take up less space when put away. The Hesh 3 also uses Bluetooth, so it can play audio wirelessly rather than relying on a cable connection. Its noise-isolating fit may help reduce outside sound during everyday listening, although that is not the same as active noise cancellation. Shoppers seeking ANC Bluetooth headphones for focus should not mistake sound isolation for an ANC feature: the listed details specify a noise-isolating fit, not active noise cancellation.
Battery life is another practical point. The published specification says up to 22 hours, and rapid charging is listed as 10 minutes for four hours of listening. It also has a microphone and controls for calls, tracks, and volume. Those features make it a self-contained listening option for commuting or taking calls without reaching for the connected device as often.
The drawback is fundamental for anyone shopping specifically for a case: this is not a case and does not protect a separate pair of Sony headphones. It is also a different headphone model, so it should not be treated as an accessory for the WH-CH720N. I put it first only as the closest match for the over-ear, portable-headphone use case represented by this shortlist. If you already own Sony headphones and need a protective shell, none of these four products is identified as one.
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.

The TOMASHI Cassette Player Tape is a portable cassette player and recorder, not a headphone case. It is aimed at people who want to play or record cassette tapes, including listeners learning a language or working with spoken material. Its compact body has physical controls for playback, rewind, fast-forward, stopping, and recording.
For private listening, the player offers a headphone mode. It also has a built-in speaker and microphone, so it can play audio aloud or record through the internal microphone. The automatic stop function releases the play button when a tape reaches its end. That feature is intended to stop the mechanism from continuing to run after playback finishes.
Power is another consideration: it can use two AA batteries or a USB power supply, neither of which is included according to the product details. The instructions also say to remove the batteries before using USB power. This is a simple, source-specific device rather than a wireless audio accessory, and its headphone connection is listed as earphone connectivity.
Its main limitation for the WH-CH720N shopper is that it does not store or protect headphones. It also serves a very different listening purpose from Bluetooth headphones: its focus is cassette playback and recording. I would consider it only if you want a portable tape player and the built-in speaker, microphone, and headphone option are useful to you. It is not a substitute for a headphone case or for wireless ANC listening.
The Sony ICF-506 is a portable AM/FM radio with analog tuning, a mono speaker, and a dedicated 3.5 mm headphone socket. It makes sense for someone who wants to listen to broadcast radio at home or carry a radio between rooms. The built-in handle supports carrying, while the option to use three AA batteries or the supplied AC adaptor gives it two ways to be powered.
The headphone socket is the most relevant feature for personal listening. It provides a wired listening route, which may suit someone who prefers not to use a speaker or wants to listen privately. That does not make the radio a Bluetooth transmitter or a headphones accessory; the listed connectivity is auxiliary, and the radio’s main function is receiving AM and FM broadcasts through its integrated tuner.
The mono speaker is designed for listening without headphones, while analog tuning keeps the controls centered on selecting radio stations. Those details give the ICF-506 a focused role: it is a radio first, rather than a general-purpose audio player. Its AC adaptor also makes it a reasonable fit for a regular indoor listening spot, with battery operation available when a wall outlet is not being used.
The trade-off is that it is much larger and heavier than a small personal audio device, and it has no stated headphone storage or protective function. It is also not wireless headphones, and the details do not identify any noise-cancelling feature. I would choose it over the other options only when AM/FM radio access and a dedicated headphone socket are the actual priorities.
The Kinboofi KZ ZS10 is a wired in-ear monitor, not a case. Its design is aimed at personal listening and monitoring, with a detachable two-pin cable and a standard 3.5 mm plug. The product details describe a stainless-steel and resin construction and a multi-driver arrangement. That makes it a more specialized choice than an everyday over-ear Bluetooth headphone.
The detachable cable is useful if you prefer a wired connection or want a cable that can be removed from the earphones. The 3.5 mm plug also gives it a straightforward connection to devices with a compatible headphone jack. A control button is listed for functions such as handling calls or changing tracks, but the specifications are inconsistent about whether a microphone is included: the product title says “No Mic,” while the feature text mentions a microphone. I would verify the exact version before choosing it for calls.
Its in-ear format may appeal to someone looking for a compact wired option for music or monitoring. But it is not a bone-conduction headphone, and the available details do not support calling it an active-noise-cancelling model. That matters for shoppers searching for the best active noise cancelling bone conduction headphones for small ears: this product is neither described as bone conduction nor clearly specified as ANC. It also is not an IPX7 waterproof true wireless earbud for streaming; it is wired, and no waterproof rating is provided.
The main trade-off is that this model’s wired, in-ear design serves a different purpose from a carrying case or wireless over-ear headphones. It can be a reasonable fit for someone who wants a detachable-cable IEM with a 3.5 mm connection, but it does not protect the Sony WH-CH720N or add storage for it. I would treat it as a separate listening product, not as an accessory for the headphones in the search.

FAQ
The Skullcandy Hesh 3 is the only listed over-ear headphone. It has Bluetooth and a collapsible design, but it is a separate headphone model rather than a case for Sony headphones.
The listed feature is a noise-isolating fit. The available details do not specify active noise cancellation, so it should not be chosen on the assumption that it has ANC.
The Sony ICF-506 has a dedicated 3.5 mm headphone socket, and the TOMASHI cassette player offers a headphone mode. The Kinboofi KZ ZS10 is itself a wired in-ear headphone with a 3.5 mm plug.
For Sony WH-CH720N owners, my recommendation is to keep looking for a purpose-made protective case: none of these four products is described as one. If you instead want a compactable over-ear headphone, I’d choose the Skullcandy Hesh 3; if you want radio or cassette playback, the Sony and TOMASHI options each serve those separate needs.
