• Generic Power Button — biggest strength: It restores the power/slider switch function on the left ear of Bose QC35 and QC45 headphones for a fraction of what a whole new headset costs.
• Generic Power Button — biggest trade-off: It's a single small repair part with no warranty listed, and it only fits those specific Bose models — nothing else.
• QearFun Kids Unicorn Headphones — biggest strength: A switchable 85dB/94dB volume limiter, a built-in mic, and a 3.5mm share port that lets two kids listen to one device without a splitter.
• QearFun Kids Unicorn Headphones — biggest trade-off: It's wired only, so there's no Bluetooth freedom, and the unicorn styling is clearly aimed at young kids rather than adults.
• Who each pick is for: Generic Power Button is for a Bose owner doing a DIY fix; QearFun is for a parent buying headphones for a child aged 3 and up.
This is a repair part, not a listening device. The Generic Power Button is a sliding spring switch replacement made for the left ear of the Bose QuietComfort 35 and QuietComfort 45. If the power slider on your QC35 or QC45 has stopped clicking or responding properly, this is the piece that brings that control back. The design brief is narrow on purpose: it's listed as compatible with the QuietComfort 35 wireless headphones I and the QuietComfort 45, and it's a single black unit.
Who should buy it: someone who already owns QC35 or QC45 headphones, has a failing left-side power slider, and prefers fixing over replacing. Who should skip it: anyone who doesn't own those exact models, anyone hoping for a warranty safety net (the sheet lists no warranty), and anyone who wants a plug-and-play listening product. This is a niche component with one job, and it does that job only for a specific set of Bose headphones.
QearFun Kids Unicorn Headphones: Who It's For
These are built for children, and every design decision points that way. The QearFun Kids Unicorn Headphones are wired over-ear headphones with a 3.5mm gold-plated jack, a 40mm dynamic driver, and a frequency range of 20Hz to 20,000Hz — normal, full-range stereo sound rather than a toy speaker. The headline safety feature is the switchable 85dB/94dB volume limiter, which lets a parent cap loudness for younger ears and open it up a bit for older kids or noisy environments.
The feature list is unusually practical for a character-themed product. There's a built-in microphone for online classes and family calls. There's a 3.5mm share port so two kids can listen from one device without a splitter — genuinely useful on road trips and flights. The earcups use memory foam, the headband is adjustable and reinforced, and the cable is a tangle-free nylon braid, which matters when the user is a six-year-old. It folds up for packing, and the 3.5mm jack works with iPads, Kindle Fire tablets, smartphones, Chromebooks and laptops.
The styling is the differentiator: the Unicorn Purple finish uses an electroplated gradient look, with a sparkly horn and decorative ears, and the theme is listed as Unicorn. It ships in gift packaging with a cable and user manual, and it carries a 1-year manufacturer warranty.
Who should buy it: parents and gift-givers shopping for a kid aged 3 and up who needs headphones for school, tablet time, or travel, especially if volume safety and sharing matter. Who should skip it: adults, anyone who wants wireless Bluetooth audio, and anyone who dislikes character-heavy design. It's wired by design — that's the trade-off for never needing a charge.
• Best for repairing a broken Bose QC35/QC45 switch → Generic Power Button. It's the only one of the two that addresses that specific fault.
• Best for a child's first headphones → QearFun Kids Unicorn Headphones. Age range starts at 3, with kid-proof materials and an adjustable headband.
• Best for hearing safety → QearFun. The switchable 85dB/94dB limiter is a concrete, parent-facing feature the repair part obviously doesn't have.
• Best for two kids sharing one screen → QearFun. The built-in 3.5mm share port removes the need for a splitter.
• Best for calls and online classes → QearFun. The built-in microphone is designed for exactly that.
• Best for extending the life of hardware you already own → Generic Power Button. Its whole purpose is restoring function instead of replacing the headset.
• Best for portability → QearFun. It folds, and the braided cable resists tangling; the power button is a small loose component.
• Best for a gift → QearFun. It arrives in gift packaging with a 1-year manufacturer warranty, which the repair part does not offer.
In my opinion, these aren't competitors at all — they're answers to two different questions, so "which is better" depends entirely on what's broken in your life. If your Bose QC35 or QC45 has a dead power slider, I'd buy the Generic Power Button; it's the targeted fix and it keeps a headset you already like in service. If you're shopping for a kid, I'd buy the QearFun Kids Unicorn Headphones without hesitation — the volume limiter, mic, share port and 1-year warranty make it the more complete product by a wide margin. For most readers landing on this comparison, the QearFun is the safer pick simply because far more people need kids' headphones than need a Bose switch. Check the current price on Amazon before deciding, since both are inexpensive enough that the math usually favors fixing or gifting over upgrading.
FAQ
Yes. They include a switchable 85dB/94dB volume limiter, so a parent can choose the lower ceiling for younger children and the higher setting when more volume is needed. That's one of the main reasons to pick them over generic kids' headphones.
They're wired, using a standard 3.5mm gold-plated jack and a tangle-free nylon braided cable. That means no charging and no Bluetooth pairing, but also no battery to run out mid-trip.
They serve different buyers, so value depends on your need. If you own QC35 or QC45 headphones with a failing power switch, the repair part is the economical route versus replacing the headset. If you need headphones for a child, the QearFun set bundles a mic, share port, volume limiter and a 1-year manufacturer warranty. Compare current prices on Amazon for both before you commit.
