How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a real, ready-to-use open-ear Bluetooth headset for video calls, choose Micool Open Ear Headphones; if you just need a fun decorative bow accessory to clip onto a headset you already own, choose NULYLU 1. These two listings aren't really rivals — one is the audio gear, the other is the styling add-on — so the right pick comes down to whether you need sound or style.
• Micool's biggest strength: a complete open-ear Bluetooth package — dual-mic noise reduction, 14.2mm dynamic drivers, touch controls, and 36H total playtime with the case. That's what actually makes a wireless headset usable for video calls.
• Micool's biggest trade-off: it's a single-purpose device you have to charge and pair, and it carries a short 6-month warranty, so you're betting on the electronics holding up.
• NULYLU 1's biggest strength: a lightweight silicone bowknot clip that changes the look of headphones you already own in seconds, with no battery, no pairing and no setup.
• NULYLU 1's biggest trade-off: it doesn't produce sound at all. It's decoration only, and it comes with no warranty.
• Pick Micool if you need the actual headset for calls, workouts or commuting. Pick NULYLU 1 if you already have a headset and want to make it playful for streaming, cheering or a themed outfit.
The Micool Open Ear Headphones is built around one idea: keep your ears open while you stay connected. The clip-on ear hooks use soft silicone memory wire, and the open-ear structure means nothing plugs your ear canal. In my opinion that's the detail that matters most for a video-call headset, because you can hear your own voice naturally instead of shouting over your own head. The case is pocket-sized at 26mm thick, so it slides into a jacket pocket or a bag side pocket without a fight.
Spec-wise, this is a genuinely modern set of internals for the category. Bluetooth 6.0 handles pairing with phones and laptops, dual-mic noise reduction cleans up your voice on calls, and low-latency audio keeps video and game sound in sync. The 14.2mm dynamic drivers are on the larger side for earbuds, which is what gives it the bass and the ambient awareness the listing leans on — useful when you're running outdoors and want to hear traffic. Battery is 8 hours per earbud and 36 hours total with the case, charged over USB-C, and there's active noise cancellation plus touch controls for playback, calls and volume.
NULYLU 1: Who It's For
The NULYLU 1 is not a headset — it's a pair of white silicone bowknot clips. Each bow measures roughly 10 x 9 x 0.5 cm, and the whole pair weighs 1.6 ounces, so it adds almost nothing to the weight of whatever you attach it to. The clip design is meant to fasten securely to headphones or earbuds without slipping, and the silicone is soft enough that it shouldn't dig in during long sessions. The listing frames it around cheerleading, streaming, gaming and party favors, and honestly that's exactly the right read.
The appeal is speed and versatility. You can swap the bows on in seconds to match an outfit or a mood, and silicone holds its color better than fabric trims, so it won't look tired after repeated use. For a female streamer or a gamer who wants her setup to look styled rather than stock, this is a cheap, low-commitment way to do it. It also works as a small party favor or birthday add-on because it's light, simple and doesn't need instructions.
Who should buy it: cheerleaders, streamers, gamers, and anyone who treats their headphones as part of an outfit. It's also a reasonable little gift for a kid who wants their headset to look "theirs." Who should skip it: anyone shopping for actual audio. There's no driver, no battery, no microphone and no Bluetooth here — if you don't already own a headset, this accessory has nothing to attach to. It also ships with no warranty and, per the listing, "see the package" as its built-in media, so don't expect extras in the box.
• Best for video calls → Micool Open Ear Headphones. Dual-mic noise reduction, Bluetooth 6.0 and low-latency audio are the exact features that make a wireless headset hold up on calls.
• Best for all-day wear → Micool Open Ear Headphones. Open-ear clip hooks plus 8H per earbud and 36H with the case cover long workdays and travel days.
• Best for workouts and running → Micool Open Ear Headphones. The sweatproof, breathable open design and ambient awareness are made for movement.
• Best for kids and lighter users → Micool Open Ear Headphones. No ear-canal pressure and auto-pairing when you open the case make it easy for younger users to just put them on and go.
• Best for styling an existing headset → NULYLU 1. If you already own headphones and want them to look themed, this is the entire point of the product.
• Best for streamers, cheer and parties → NULYLU 1. Quick changes, silicone durability and a look that reads instantly on camera.
• Best "no setup" pick → NULYLU 1. Nothing to charge, pair or update — clip it on and you're done.
• Best one-and-done purchase → Micool Open Ear Headphones. It's the only one of the two that actually plays sound.
If I were buying for myself, I'd get the Micool Open Ear Headphones. For video calls specifically, it's the only one of the two that can do the job at all — Bluetooth 6.0, dual-mic noise reduction, 36H total playtime and touch controls cover the whole day without babysitting a charger. The NULYLU 1 is charming and does exactly what it promises, but it's a decoration, and decorations don't pick up your voice. Buy Micool for function, add NULYLU 1 later if you want your setup to look fun. Just check the current price on Amazon before you commit, since both listings can move.
Yes, on paper it's built for it: Bluetooth 6.0 for stable pairing with phones and laptops, dual-mic noise reduction for your voice, and low-latency audio so lips and sound stay in sync. The open-ear fit also means you hear yourself naturally while talking.
Can I use the NULYLU 1 as a headset for calls?
No. It's a decorative silicone bowknot accessory with no drivers, microphone, battery or wireless connection. It clips onto headphones you already own — it doesn't produce or transmit sound.
They solve different problems, so "value" depends on what you need. If you need working audio, the Micool Open Ear Headphones is the only one that delivers it. If you already have a headset and only want a style upgrade, the NULYLU 1 does that for very little. Check the current price on Amazon for both.
The clip design is meant to fasten securely to headphones and earbuds, and the bows are about 10 x 9 x 0.5 cm with a 1.6-ounce pair weight, so they're light enough for most frames. Thin or unusually shaped arms are the main risk — measure your headband before ordering.
