How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a transmitter that lets two people watch TV through their own headphones at the same time, choose SOOMFON 5.3; if you need true wireless earbuds for toddlers with a long battery and a secure over-ear hook, choose CASCHO Ear buds.
• SOOMFON 5.3 – biggest strength: It is a Bluetooth 5.3 transmitter/receiver that sends audio from a TV, PC or stereo to two Bluetooth headphones at once, with Optical, AUX and RCA inputs.
• SOOMFON 5.3 – biggest trade-off: It has no microphone, needs its own DC power, and its volume control is not independent for the two connected devices.
• CASCHO Ear buds – biggest strength: True wireless earbuds with 60 hours of total listening time, a 14.5mm graphene driver for deep bass, and IPX7 water resistance in an over-ear hook design.
• CASCHO Ear buds – biggest trade-off: There is no active noise cancellation, and the fit depends on choosing the right eartips for a proper seal.
• Who each pick is for: SOOMFON 5.3 is for someone with a non-Bluetooth TV or stereo who wants private listening; CASCHO Ear buds are for a parent who wants wireless earphones for toddlers and doesn't want anything falling out.
The SOOMFON 5.3 is not an earbud. It is a small blue ABS box — about 3.31 by 0.43 by 1.3 inches, 72 grams, with a 1.8-inch LCD — and its whole job is to take audio out of a device that has no Bluetooth and hand it to something that does. Optical, 3.5mm AUX and RCA are all supported on the input side, and it broadcasts to Bluetooth headphones, speakers or soundbars on the other.
The feature that matters most here is dual connection. Two Bluetooth headsets or speakers can be paired at the same time, which means two people can watch the same movie at their own volume without disturbing anyone else in the room. Once the first pairing is done, both devices reconnect automatically the next time. The range is genuinely wide — the spec lists a stable connection up to 10–30 meters, closer to 10–20 meters when there's an obstacle in the way, and 10–30 meters in open space. You can walk to the kitchen mid-episode and not lose the audio.
The LCD status indicator is a small but real convenience; you can see what mode the unit is in instead of guessing from a blinking light. There are built-in volume buttons, which is useful precisely for headphones like AirPods that don't have their own controls, though the volume is shared between both connected devices rather than independent per headphone.
CASCHO Ear buds: Who It's For
The CASCHO Ear buds are the opposite kind of product — a pair of true wireless earbuds in blue, built around an over-ear hook rather than a plain in-ear shape. Each bud runs about 10 hours on its own, and the 650mAh charging case adds five more charges for up to 60 hours total. The case has a digital display showing each side's remaining power in 25% segments, which beats squinting at a single LED.
Audio comes from a 14.5mm graphene diaphragm — a large driver for this category — with a stated 20Hz–20,000Hz range and 140-ohm impedance. The emphasis is on bass that carries through to the mids and highs rather than a thin, tinny sound. There's a built-in microphone for calls, and Bluetooth 5.3 handles the connection, with auto-pairing when you open the lid and auto-disconnect when you put them back.
The physical design is what separates these from generic earbuds. Soft silicone over-ear hooks with a non-slip tip hold each bud in place, and IPX7 water resistance means rain and sweat aren't a problem — though CASCHO's own guidance is clear that these are for workouts, not swimming or bathing. Button controls handle play/pause, track changes, volume, Siri and calls, and the button approach avoids the accidental taps that touch controls cause during movement. The buds also switch between stereo and mono mode, so one earbud can be used alone or shared.
Who should buy them: anyone who wants earphones for toddlers that stay put — the hook design plus the mono-mode option means a child can wear one bud while a parent keeps the other, and there's nothing to lose in a couch cushion. They also suit runners, gym-goers and anyone working in weather. Skip them if you need active noise cancellation — there is none, and CASCHO suggests trying different eartips for a better seal — or if you want a fully sealed, cable-free listening experience for swimming.
• Best for watching TV with two people → SOOMFON 5.3, thanks to dual headphone connection and automatic reconnection.
• Best for true wireless earbuds for toddlers → CASCHO Ear buds, with over-ear hooks and a non-slip tip that resist pulling free.

• Best for workouts and wet weather → CASCHO Ear buds, with IPX7 water resistance and sweat-friendly silicone hooks.
• Best for stereo systems, PCs and older TVs → SOOMFON 5.3, which accepts Optical, AUX and RCA and sends audio to Bluetooth headphones or speakers.

• Best for kids sharing one device → CASCHO Ear buds in mono mode, so one bud can be used at a time.
For a toddler, I would buy the CASCHO Ear buds. The over-ear hook and non-slip silicone tip are the single most important design detail when the wearer is small and constantly moving, and the 60-hour total playtime means you're not recharging every evening. Mono mode lets a child use one bud while a parent keeps the other, and IPX7 means a bit of rain or sweat won't end the session. The SOOMFON 5.3 is the better tool for a completely different job — private TV listening for two people at once — but it isn't something a toddler wears. In my opinion, if the question is earphones for toddlers, the CASCHO is the one I'd hand over.
FAQ
The over-ear hooks, soft silicone and non-slip tips are designed to stay put during movement, and the button controls resist accidental touches. They aren't marketed specifically for children, so a parent should judge fit and volume themselves.
Yes. Dual connection is a core feature — two Bluetooth headsets or speakers can be paired simultaneously, with automatic reconnection after the first pairing. Just note that the volume control is not independent for the two devices.
They solve different problems, so value depends on the job. If you need to get audio out of a non-Bluetooth TV or stereo, the SOOMFON 5.3 is the only one of the two that can do it; if you want wireless earbuds for a child or for workouts, the CASCHO is the relevant purchase.
