If you want over-ear Bluetooth headphones for calls, choose iJoy Squishmallows; if you need a lightweight tether for compatible AirPods, choose KAKUKAKU Lightweight Silicone Lanyards. For calls, iJoy is the direct choice: it has a built-in microphone and Bluetooth audio. KAKUKAKU is an accessory that keeps compatible earbuds connected to each other when you take them out of your ears; it does not provide audio or call functions by itself.
• iJoy Squishmallows’ biggest strength: over-ear Bluetooth headphones with a built-in mic, up to 15 hours of battery life, and a foldable design. Trade-off: they are headphones, not a tether for earbuds you already own.
• KAKUKAKU’s biggest strength: two 55 cm silicone lanyards, in black and white, for tethering compatible AirPods models. Trade-off: it does not contain speakers, a microphone, Bluetooth, or a battery.
• Choose iJoy if you want a standalone listening option for music, video, and hands-free calls.
• Choose KAKUKAKU if you already use compatible AirPods and want a simple way to keep them joined when they are out of your ears.
• These products address different problems. The deciding question is whether you need headphones or an accessory for earbuds you own.
iJoy Squishmallows is a pair of wireless over-ear headphones with a built-in microphone. That makes it the only one of these two picks that can serve as a call headset on its own. You can pair it over Bluetooth, listen to audio, and use the mic for hands-free calls. For someone choosing sleep headphones for calls, the basic appeal is clear: this is a padded, over-ear set with a call microphone, rather than an earbud strap. That said, the product information does not establish that it is designed specifically for sleeping, so I would treat that phrase as a search need, not a promise about sleep comfort.
The listed battery life is up to 15 hours, while the stated Bluetooth range is up to 33 feet. Those figures suggest room for extended listening and some movement away from the connected device within the stated range. The headphones also fold for storage, which may help if you want to put them away between uses or carry them during a commute. A 3.5 mm headphone jack is listed as well, alongside wireless Bluetooth connectivity, giving the headset a wired connection option. A USB charging cable is included, though no charging-time figure is provided.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
The over-ear fit has plush padded ear cups, and the listed color is teal. Squishmallows character styling is part of the product’s appeal, especially for a fan looking for headphones with a playful look rather than a plain headset. The listed controls include touch control and push-button control, and the product information names hybrid noise cancellation. It does not explain how that noise-control feature performs or provide further detail, so I would not assume a particular level of isolation.
Who should skip it: Skip iJoy if your goal is to tether AirPods you already own; these are standalone headphones, not an earbud holder.
KAKUKAKU is not a headphone set. It is a two-piece silicone lanyard accessory intended to connect compatible earbuds, including AirPods Pro 3, Pro 2, Pro 1, and standard AirPods models listed in its compatibility information. The flexible ends stretch around the earbud stems, while the 55 cm cord links the two sides. When you take the earbuds out to talk, order coffee, or handle a quick interruption, they can hang together rather than being held separately.
The lightweight silicone design is the central point. Each strap is listed at 2.86 g, and the package contains two straps: one black and one white. This makes the set useful for a person who wants a simple, low-profile tether and would like a second strap for another compatible pair or to share. The stated length is 55 cm, or about 21.6 inches. It is intended to allow some movement while limiting excess cord that could catch on clothing, zippers, or a bag. That is a design aim, not a guarantee that snagging can never happen.
The practical trade-off is just as important: the lanyard does not make an earbud set into Bluetooth headphones, add a microphone, or improve battery life. It depends on having compatible earbuds already. Although it can help keep the earbuds together when they are removed, the data does not describe call quality, audio performance, or a charging feature. For a shopper searching for usb c charging bluetooth earbuds for calls, KAKUKAKU is not the answer to the audio or charging part of that need; it is only a tether accessory.
Who should skip it: Skip KAKUKAKU if you need headphones for calls or do not own earbuds covered by its compatibility list.
• Best for making calls without buying a separate tether → iJoy Squishmallows. It is the only option here with a built-in microphone and Bluetooth audio.
• Best for keeping compatible AirPods together when removed → KAKUKAKU. Its flexible silicone ends attach to the earbuds, and the cord joins them.
• Best for longer listening between charges → iJoy Squishmallows. The listed battery life is up to 15 hours; the lanyard has no battery because it is not an audio device.
• Best for packing away a headset → iJoy Squishmallows. Its foldable design is a practical feature for storage and commuting.
• Best for a lightweight accessory → KAKUKAKU. Each silicone strap is listed at 2.86 g, and two are included.
• Best if you want a wired connection option → iJoy Squishmallows. A 3.5 mm headphone jack is listed in addition to Bluetooth.
• Best if you want two color choices in the package → KAKUKAKU. The set includes one black strap and one white strap.
• Best for a Squishmallows fan → iJoy Squishmallows. The character styling is part of the headphone design; KAKUKAKU is a plain silicone accessory.
Start with the device you want to use. If you do not already own compatible AirPods, KAKUKAKU does not give you a way to listen or make calls. Its purpose is to connect certain earbuds to each other, so the fit and compatibility list matter more than headphone features. Check that your exact AirPods model is included before choosing it. The provided compatibility information names AirPods Pro 3, Pro 2, Pro 1, and standard generations, but does not give a detailed fit guide for other earbuds.
If your priority is an all-in-one listening product, iJoy is the relevant choice. It has wireless Bluetooth connectivity, a built-in mic, up to 15 hours of battery life, and a 3.5 mm jack. Those details make it more suitable for someone comparing the best Bluetooth headphones for calls than a silicone tether would be. Still, the specs do not state call-microphone performance, charging time, or how the listed noise-control feature behaves in different settings. Consider those unknowns rather than treating a feature name as proof of a particular result.
Think about how you will carry or use the product. iJoy’s foldable construction is useful if you want a headset that can be stored after listening, while the over-ear design and padded cups are aimed at covering the ears. KAKUKAKU instead stays attached to compatible earbuds and lets them hang together when not being worn. That can suit a routine with frequent brief interruptions, but it also means wearing a cord between the earbuds when they are in use. Neither product’s supplied facts support a claim that it is suitable for every activity or setting.
The two-item package is another practical distinction. KAKUKAKU includes a black and a white strap, so you can keep one as a spare or use the second with another compatible set. iJoy is a single headset, with a USB charging cable, an audio cable, and a user manual listed among the included items. Those accessories support different needs: one product is a reusable tether for earbuds, while the other is a complete headphone set with both wireless and wired connection options.
For calls, I would choose iJoy Squishmallows because it is the only product here that supplies headphones, Bluetooth audio, and a built-in microphone in one device. Its up-to-15-hour battery figure, foldable design, and 3.5 mm jack add useful flexibility.
I would choose KAKUKAKU only if I already owned compatible AirPods and specifically wanted a light silicone tether.
The two products are not substitutes, but iJoy is my pick for someone deciding between them with calls as the main use.
No. KAKUKAKU is a silicone tether for compatible AirPods models, not an audio device. It has no listed microphone, speakers, Bluetooth connection, or battery.
They include a built-in microphone for hands-free calls, along with Bluetooth connectivity. The product information does not provide call-quality test results, so it supports calling as a use case without specifying how the mic will perform in every environment.
It depends on the commute need. iJoy offers foldable over-ear headphones, wireless listening, and up to 15 hours of listed battery life. KAKUKAKU is designed as a lightweight tether for compatible earbuds, useful when you often remove them briefly during a commute.
No. The set contains two silicone lanyards, one black and one white. It does not include earbuds or a charging feature; it connects compatible earbuds so they remain joined when removed.
