If you want a purpose-built protective case for compatible JBL kids’ headphones, choose Aenllosi Hard Carrying Case; if you need wired, open-ear stereo headphones for everyday listening, choose JJLFresheners Black Retro. For remote work, the key difference is simple: one stores and protects a separate headset, while the other is a headset you can connect to a device with a 3.5 mm jack.
Aenllosi Hard Carrying Case vs JJLFresheners Black Retro at a Glance
• Aenllosi’s biggest strength: A hard EVA shell designed to help protect compatible headphones from bumps, scratches, and splashes. Trade-off: It is the case only; headphones and accessories are not included.
• JJLFresheners’ biggest strength: Lightweight, wired on-ear headphones with an adjustable headband and an open-ear design. Trade-off: They require a 3.5 mm headphone jack and have no noise control.
• Choose Aenllosi if you own JBL JR 300BT, JR 300, or compatible kids’ on-ear wireless headphones and want a dedicated case for carrying or storage.
• Choose JJLFresheners if you want wired listening, an adjustable fit, and an open design that leaves you more aware of your surroundings.
• Neither is a direct substitute for the other: one protects headphones; the other provides audio.
Aenllosi is for someone who already has compatible headphones and wants to keep them enclosed between uses. The case is made from EVA and has a hard shell. Its stated protective qualities include resistance to crushing and shocks, plus water resistance intended to help with splashes. That makes its purpose clear: give a small headset a more protective place in a backpack, drawer, or travel bag than leaving it loose among other items.
Inside, a mesh pocket provides space for accessories. That can help keep small extras together with the headphones rather than loose in a bag, though the product information does not specify how many accessories fit. The case weighs 150 g. Its listed internal size is 6.2 inches and external size is 7.2 inches; the separate item dimensions are 7.3 x 5.5 x 2.4 inches. Those figures describe a compact carrying case, but fit should still be checked against the headphones you plan to store.

JJLFresheners is the actual listening option here. It is a wired, on-ear stereo headphone with an adjustable headband, a lightweight portable build, and an open-ear architecture. The on-ear cushions sit against the ears rather than enclosing them. The open-back design is described as helping reduce heat build-up during extended listening, while also allowing the wearer to remain aware of their surroundings.
For remote work, that design may suit someone who listens to music or other audio while still wanting to notice activity nearby. It could be a reasonable fit for a home office where full isolation is not the goal. The adjustable headband offers a way to customize the fit, although the product information does not give a headband range or cushion dimensions. Its dynamic drivers have a listed frequency range of 20 Hz to 20,000 Hz. That is a technical specification, not a guarantee of a particular sound preference or performance in every work setting.
The connection is wired through a 3.5 mm headphone jack. That avoids relying on a wireless connection, but it means the listening device needs a compatible jack. The listed control method is push button and remote, and the noise-control field says none. In practical terms, don’t choose these if blocking surrounding sound is central to your work routine. Who should skip them: skip JJLFresheners if your device lacks a 3.5 mm jack, or if you need noise control or a protective carrying case.
• Need a protective case for compatible JBL kids’ headphones → Aenllosi. Its hard EVA shell is designed to help guard against bumps, scratches, and splashes.
• Need headphones for listening during a workday → JJLFresheners. Aenllosi is a case only, while JJLFresheners is the audio product.
• Want a place to keep small accessories with a headset → Aenllosi. The internal mesh pocket is intended for accessory storage.
• Prefer a wired connection → JJLFresheners. It connects through a 3.5 mm headphone jack, so confirm that the device you plan to use has one.
• Want an open design that maintains awareness of your surroundings → JJLFresheners. That same openness is a trade-off if you want to limit outside sound.
• Need a case that weighs 150 g → Aenllosi. Its listed weight is useful to know when considering what you’ll carry, but it does not describe the weight of any headphones stored inside.
• Looking for long battery life headphones for remote work → neither product answers that need directly. Aenllosi is a case, and JJLFresheners is wired, so the comparison is not about wireless battery performance.
• Searching for the best gaming headset for remote work → neither is described as a gaming headset. JJLFresheners can provide wired stereo listening, but the listed features do not establish gaming-specific functions.
• Interested in hi-fi stereo open-ear headphones for remote work → JJLFresheners is the closer match in design. It is described as wired stereo and open-ear, but the available specifications do not establish hi-fi performance.
Buying Considerations
Start by identifying the item you actually need. If you already own compatible JBL headphones, Aenllosi may add useful protection when the headset is put away or carried. If you don’t own headphones, the case will not solve your listening needs. The product listing specifically describes the sale as the case only, with the device and accessories not included.
Consider the environment, too. The open-ear design is presented as a way to stay aware of nearby sounds and reduce heat build-up. That may be welcome at home, but an open design is not the same as noise isolation. If you share a busy workspace or need to shut out surrounding noise, the listed features do not indicate that JJLFresheners will do so.
Finally, keep the categories straight when comparing them. Aenllosi’s size and shell details concern storage and protection. JJLFresheners’ fit, drivers, and wired connection concern listening. They are not two versions of the same kind of product, so the right decision follows from whether your priority is protecting an existing headset or choosing a wired pair for everyday audio.
In my opinion, I’d choose JJLFresheners if I needed wired headphones for remote work and had a device with a 3.5 mm jack. Its adjustable headband and open design fit a listening routine where awareness of the room matters. I’d choose Aenllosi only when I already owned compatible JBL kids’ headphones and wanted a dedicated hard case. The deciding factor is the job: audio with JJLFresheners, protection with Aenllosi.
It is a hard carrying case for compatible JBL JR 300BT, JR 300, and kids’ on-ear wireless headphones. The headphones and accessories are not included.
No Bluetooth connection is specified for listening; the headphones are wired and use a 3.5 mm headphone jack. Check that your device has a compatible jack before choosing them.
Are JJLFresheners headphones a good choice if I need to block office noise?
The listed noise-control feature is “None,” and the open-ear design is intended to maintain awareness of surroundings. They are not described as noise-isolating headphones.
