If you want simple wired listening for everyday devices, choose MANHATTAN On-Ear; if you need a protective carrying case for compatible JBL headphones, choose Mchoi Hard. For swimming, neither is designed to be worn in the water: one is a wired on-ear headphone and the other is an empty storage case.
• MANHATTAN On-Ear’s biggest strength: A lightweight, adjustable wired headphone with a 6-foot cable and a standard 3.5 mm plug. Trade-off: It is on-ear and wired, not a swimming headphone.
• Mchoi Hard’s biggest strength: A hard EVA case with a mesh pocket, hand strap, and carabiner for compatible JBL headphones. Trade-off: It is only a case; the headphones are not included.
• Choose MANHATTAN On-Ear if you need a straightforward wired listening option for a device with a 3.5 mm jack.
• Choose Mchoi Hard if you already own JBL Tune 500BT, 510BT, or 520BT headphones and want a dedicated case for carrying them.
• These are not direct substitutes. MANHATTAN On-Ear produces sound; Mchoi Hard protects certain headphones when they are not being used. The right choice starts with deciding whether you need headphones or a carrying case.
MANHATTAN On-Ear is a simple wired stereo headphone for listening through devices with a 3.5 mm jack. Its 6-foot cable gives some room to move between the headphones and a nearby laptop or desktop. That extra reach can be useful at a desk, where a shorter lead might pull when you shift in your chair. The connection is a single 3.5 mm plug, so there is no wireless pairing step involved.
The lightweight design, foam ear cushions, and adjustable split headband point toward basic, uncomplicated listening. The headband can be adjusted for fit, while the foam pads provide a cushion where the headphones rest on the ears. Its listed frequency range is 20 Hz to 20 kHz, and its dynamic drivers provide stereo audio. Those specifications describe the headphone’s audio range and driver type; they do not make it a swimming model or establish active noise cancellation.
This could suit someone who wants wired headphones for a computer, tablet, phone, or older audio player that has a compatible jack. It is also the more relevant option of these two for someone shopping for a headphone, rather than an accessory. Who should skip it: Anyone looking specifically for headphones to wear while swimming, wireless listening, or active noise cancellation should look elsewhere. It is an on-ear wired design, not a waterproof swimming headphone.

Mchoi Hard: Who It's For
Mchoi Hard is a carrying case made for JBL Tune 500BT, 510BT, and 520BT on-ear wireless headphones. It does not play audio and does not include the headphones. That distinction matters: this is an accessory for someone who already owns a listed compatible model, not an alternative to MANHATTAN On-Ear as a listening device.
The case uses hard EVA construction, which is intended to help protect its contents from knocks and exposure to water. The listing also describes it as dustproof. A full-perimeter zipper opens and closes the case, and a built-in mesh pocket gives small accessories a place to go. The hand strap offers a way to carry it directly, while the carabiner can attach the case to a purse, backpack, or bag. These details make it practical for packing or carrying compatible headphones between places.
• Need headphones that produce sound → MANHATTAN On-Ear. Mchoi Hard is a protective case, not an audio product.
• Need a case for JBL Tune 500BT, 510BT, or 520BT → Mchoi Hard. Its fit is specified for those models.
• Want a wired connection → MANHATTAN On-Ear. It uses a single 3.5 mm plug and a 6-foot cable.
• Want to carry small accessories alongside compatible headphones → Mchoi Hard. Its built-in mesh pocket is designed for extra storage.
• Want a carrying option that can attach to a bag → Mchoi Hard. It includes a hand strap and a carabiner.
• Prefer adjustable headphones with foam ear cushions → MANHATTAN On-Ear. Its split headband adjusts, and the earpads are cushioned with foam.
• Shopping for the best in ear headphones for swimming → Neither. MANHATTAN On-Ear sits on the ears, and Mchoi Hard is a case; neither sheet describes an in-ear swimming headphone.
• Looking for the best noise canceling headphones for swimming → Neither. MANHATTAN On-Ear lists sound isolation, not active noise cancellation, and Mchoi Hard has no audio features.
• Want a case with a hard protective shell → Mchoi Hard. Its EVA construction is described as shockproof and waterproof, though the case itself is not a headphone for use in water.
One search phrase that can mislead here is “best hi res sleep headphones for swimming.” Neither product’s listed features support that combination of use. MANHATTAN On-Ear is a wired on-ear headphone with a specified frequency range, but no high-resolution certification or swimming design is stated. Mchoi Hard stores compatible headphones; it does not provide sound or make stored headphones suitable for swimming.
My Verdict
For a listening device, I would choose MANHATTAN On-Ear because it is the only one here that actually supplies audio, with an adjustable fit, foam cushions, and a 6-foot wired connection. For carrying compatible JBL headphones, Mchoi Hard is the clear choice because its hard EVA shell and carrying features serve that separate job. For swimming, though, I would buy neither: neither product is described as a headphone designed to be worn in water.
First, decide whether you need headphones or protection for headphones. MANHATTAN On-Ear is the listening product; Mchoi Hard is an empty case. Comparing them as if they were two headphones would lead to the wrong purchase.
For MANHATTAN On-Ear, check the device you plan to connect. The headphone uses a 3.5 mm jack, so your device needs a compatible connection. The 6-foot cable is useful when the audio source is some distance away, but it remains a cable to manage. Its on-ear placement may also be a poor match if you specifically want an in-ear fit or a headphone intended for swimming.
For Mchoi Hard, compatibility is the first practical check. The listed fit is for JBL Tune 500BT, 510BT, and 520BT models. It is not a universal headphone case, and the headphones themselves are not included. Consider the stated dimensions—8.2 by 6.8 by 1.7 inches—when deciding whether it fits your bag or storage space. Its mesh pocket, hand strap, and carabiner add carrying options, while its rigid EVA build is aimed at protecting the stored headphones.
If you are comparing the products as possible purchases for swimming, the central issue is not which one has more useful accessories. It is that neither is described as a swimming headphone. MANHATTAN On-Ear is an on-ear wired model, and Mchoi Hard is a storage case with no audio function. Check the current price on Amazon if price matters to your decision; the product information here does not establish one.
It is not described as a swimming headphone. Its listed design is on-ear, wired, and connected through a 3.5 mm plug. The product information does not specify a waterproof rating for the headphones.
No. It is an empty protective case, not a headphone set. It is listed as compatible with JBL Tune 500BT, 510BT, and 520BT headphones.
The listed noise-control type is sound isolation. The product information does not state that it has active noise cancellation, so do not treat it as a noise-canceling model.
Choose Mchoi Hard if you own one of its compatible JBL models and want a hard case with a mesh pocket, hand strap, and carabiner. Choose MANHATTAN On-Ear if you need wired headphones; its 6-foot cable and 3.5 mm plug are the relevant features.
