If you want a dedicated, impact-conscious travel case for HD660S2 headphones, choose ECVGHD Durability Hard Protective; if you need wearable audio for sleeping, workouts, or hands-free listening, choose Mixiba Sleeping Headphones. For airplane travel, I’d choose based on what you need to protect or wear: ECVGHD stores specific headphones, while Mixiba is itself a Bluetooth headband with up to 14 hours of listening time.
ECVGHD Durability Hard Protective vs Mixiba Sleeping Headphones at a Glance
• Mixiba’s biggest strength: An adjustable fabric headband provides Bluetooth audio without traditional in-ear earbuds, with up to 14 hours of playtime. Trade-off: It is wearable audio, not a protective case for another pair of headphones.
• Best for protecting HD660S2 headphones during a commute or trip: ECVGHD Durability Hard Protective.
• Best for listening while resting, exercising or moving around: Mixiba Sleeping Headphones.
• Choose ECVGHD if you already own compatible headphones and want them held in place during transport; choose Mixiba if you want an adjustable headband with built-in audio and controls.
ECVGHD is a carrying case designed specifically for HD660S2 headphones. Its molded interior is intended to cradle the earcups and headband, while elastic inner straps help hold the headphones in position. That layout matters when a pair is being carried with a cable: the case is designed to help keep the contents organized and reduce tangling, rather than leaving the headphones loose among other items.
The outer construction combines Oxford fabric with shock-absorbing EVA foam. In practical terms, that gives this case a more structured protective role than a simple fabric pouch: its materials are intended to help guard the headphones from bumps and scratches in a backpack or luggage. A reinforced handle strap offers another way to carry it, and the case is described as compact and lightweight. Its listed dimensions are approximately 22 × 20 × 12 cm, so buyers can consider those measurements when deciding how it might fit with their travel gear.
I’d consider ECVGHD for someone who owns HD660S2 headphones and wants a dedicated place for them on commutes, trips, or outdoor outings. Its most important limitation is also clear: it does not include headphones, Bluetooth, or listening features. The product information identifies the case as designed for HD660S2, so I would not assume its molded fit is right for other headphone models.
Who should skip it: Skip ECVGHD if you’re looking for wearable audio, or if you don’t own the headphone model this case is designed to hold.
For airplane travel, the case suits a traveler who wants to pack HD660S2 headphones with their belongings and keep them organized. It does not, however, function as a headset for listening to music or taking calls. That distinction is easy to miss when comparing it with Mixiba: one product protects a separate pair of headphones, and the other is a pair of headphones built into a wearable headband.
Mixiba takes the opposite approach. It combines a fabric headband and thin speakers into a Bluetooth listening product. The hook-and-loop closure lets the wearer adjust the fit instead of relying on a fixed-size band. That adjustability could be useful if a snug or loose fit is a concern, or if the headband will be worn in different situations, such as relaxing at home, meditating, traveling, or working out.

Mixiba uses Bluetooth 5.4 and is listed for up to 14 hours of listening on a full charge, with a two-hour charging time. Built-in buttons let the wearer adjust volume, change tracks, play or pause audio, and manage calls without reaching for a phone. That could be convenient when hands are occupied during a workout, while cooking, or while traveling. The trade-off is that the product is a fabric headband with thin speakers, not a hard-sided case or a conventional headset with stated noise-cancelling capabilities.
Who should skip it: Skip Mixiba if you need a protective travel case for HD660S2 headphones, or if your key requirement is documented noise cancellation.
For airplane travel, Mixiba may make sense if you want wearable Bluetooth audio and the headband form suits you. Its listed playtime can cover extended listening, but the provided specifications do not establish how effectively it reduces cabin noise, how its call audio compares with a dedicated headset, or whether it will work with any particular in-flight entertainment system. Those are worth checking against your own needs rather than assuming from the wireless feature alone.
It is also a different kind of choice for buyers searching for deep bass headphones for computer use. The sheet identifies Mixiba as a headband with thin speakers, but does not give sound-response or bass specifications. I would not infer a particular bass character or computer setup compatibility from the product details provided.
• Best for storing HD660S2 headphones → ECVGHD Durability Hard Protective. Its molded interior and elastic straps are meant to hold that headphone model in place.
• Best for adjustable wearable listening → Mixiba Sleeping Headphones. Its hook-and-loop closure allows the wearer to change the tightness of the band.
• Best for impact-conscious packing → ECVGHD Durability Hard Protective. Oxford fabric and shock-absorbing EVA foam give it a protective storage role.
• Best for a workout headband → Mixiba Sleeping Headphones. The fabric is stretchy and breathable, and the band is designed to help keep sweat away from the eyes.
• Best for extended wireless listening by the stated battery figure → Mixiba Sleeping Headphones. It lists up to 14 hours of playtime and a two-hour charge.
• Best for carrying headphones with less cable clutter → ECVGHD Durability Hard Protective. Its interior straps and shaped compartments are intended to help secure the headphones and keep cables from tangling.
• Best for on-head controls → Mixiba Sleeping Headphones. Buttons on the headband handle volume, track changes, playback and calls.
• Best for a buyer seeking the best noise cancelling bluetooth headset for airplane → Neither can be confirmed from these details. Mixiba is Bluetooth, but no noise-cancellation feature is listed; ECVGHD is only a carrying case.
In my opinion, I’d buy Mixiba if I wanted one of these products for airplane travel as a listening companion: it is the only one of the two that provides Bluetooth audio, adjustable wear and built-in controls. Its up-to-14-hour playtime is a useful stated feature for a long journey, though I would not count on it for noise cancellation that is not specified.
I’d choose ECVGHD instead if I already owned HD660S2 headphones and needed a dedicated case to carry them. These products solve different problems, so my pick changes with the job: Mixiba for wearable listening, ECVGHD for protecting compatible headphones.
Buying Considerations
Before choosing, separate your need for audio from your need for storage. Mixiba is the listening product; ECVGHD is the case. If you need both a headset and a way to protect a separate pair of headphones, neither product alone covers both jobs.
For Mixiba, consider whether a headband is the form you want for sleeping, exercise or travel. Its adjustable closure and fabric construction are central to the design. The battery figure is up to 14 hours, and the listed charge time is two hours, but individual listening conditions are not described. If noise reduction, a particular sound profile or dependable call clarity is essential, the available specifications do not establish those outcomes. In particular, the phrase crystal clear calls wireless headset describes a shopper’s goal, not a performance claim supported by the product details here.
If price affects your decision, check the current price on Amazon before choosing; the right comparison still starts with whether you need a case or wearable audio. Also consider what you’ll carry on a trip: ECVGHD is intended to travel inside a backpack or luggage, while Mixiba is worn on the head and includes buttons for managing audio and calls. Neither choice should be treated as a substitute for a feature the product details do not state.
FAQ
The product details describe Mixiba as a wearable Bluetooth headband with thin speakers, not as a storage case. For a dedicated HD660S2 case, ECVGHD is the relevant option.
Noise cancellation is not listed in the provided product details. Mixiba offers Bluetooth audio and an adjustable fabric headband, but those facts alone do not establish that it blocks or cancels cabin noise.
It depends on whether you need to listen or pack headphones. Mixiba lists up to 14 hours of listening time; ECVGHD is meant to carry and protect HD660S2 headphones, not provide audio.
