How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a pair of wired earphones that plugs into virtually anything with a 3.5mm port and never needs charging, choose Betron BS10; if you need wired earbuds built specifically for iPhone's Lightning connector and want a spare pair in the box, choose CREHAO 2.
• Betron BS10 — biggest strength: universal 3.5mm plug, 12mm dynamic drivers, inline volume control and mic, passive noise isolation through the in-ear fit, and a 12-month warranty.
• Betron BS10 — biggest trade-off: no Lightning or USB-C connector, so newer phones without a headphone jack need an adapter, and its noise control is passive isolation only — no electronic cancellation.
• CREHAO 2 — biggest strength: a two-pack of Lightning-connector earbuds aimed squarely at iPhone owners, with a built-in mic, multifunction button and adaptive noise cancellation.
• CREHAO 2 — biggest trade-off: it only fits Lightning devices (iPhone 14 and older iOS hardware), so Android phones, laptops and gaming controllers are out unless they use that same connector.
• Who Betron BS10 is for: anyone who wants one pair of earbuds that works across phones, tablets, laptops and controllers.
• Who CREHAO 2 is for: iPhone users who want wired listening without adapters, and who like having a backup pair on hand.
The BS10 is the "just works everywhere" option. It's a wired in-ear earbud with a standard 3.5mm jack, so it drops straight into a phone with a headphone port, a tablet, a laptop, a desktop or a gaming controller — no pairing, no battery, no charging case to remember. That alone makes it the more flexible pick if your devices are a mixed bag.
Inside, Betron uses 12mm dynamic drivers with a 20 Hz–20,000 Hz frequency range, 16 ohm impedance and 112 dB sensitivity. In plain terms: that low impedance and high sensitivity combination is easy to drive, which is what you want from something you'll plug into a laptop headphone jack or a controller rather than a dedicated amp. The tuning leans toward bass, which suits commutes, gaming and general listening. There's an inline mic plus volume controls on the cable, so calls and track changes don't require pulling your phone out.
The fit side is handled with silicone tips in three sizes and a passive, in-ear seal — it blocks some outside noise, but Betron is clear that this is isolation, not active noise cancellation. Expect it to take the edge off train rumble and office chatter, not erase it. You also get a storage pouch and a 12-month warranty against manufacturing defects. Buy it if you want one set of earbuds for several devices and you value not thinking about charging. Skip it if your phone has no 3.5mm port and you'd rather not deal with an adapter, or if you specifically need active noise cancellation.
The CREHAO 2 is a different animal entirely: it's a two-pack of wired earbuds with a Lightning connector, built for iPhone. CREHAO lists compatibility across iPhone 14, 14 Pro, 14 Pro Max, 13 series, 12 series, SE, 11 series, XS Max, X, XR, 8/8 Plus, 7/7 Plus and all iOS systems. If you own one of those phones, this is plug-and-play wired audio with zero adapter involved — which is the whole appeal.
Feature-wise, you get a built-in microphone and a multifunction button on the cord. A single button handles answer/end call, play/pause and track skipping, and you can adjust volume from the remote rather than reaching for the phone. CREHAO describes the drivers as tuned to maximize output and minimize sound loss, with enhanced bass, and the listing notes a noise-reduction design that "can reduce the impact of external noise." The spec sheet lists adaptive noise cancellation as the noise-control type, alongside 80 ohm impedance.
That 80 ohm figure is worth pausing on. It's noticeably higher than typical phone-oriented earbuds, and higher impedance generally means a source has to work a little harder to reach the same loudness — fine on a phone's own Lightning output, but it's a design detail rather than a headline. The other practical point: you get two pairs. That's genuinely useful if you keep one in a bag and one at a desk, or if a cable eventually wears out. CREHAO rates the build as durable and easy on the wallet, and backs it with an 18-month warranty. Buy it if you're on an iPhone with a Lightning port and want wired buds with no dongle. Skip it if you need to use the same headphones with an Android phone, a laptop or a console — this set won't connect to those.
Side-by-Side: Which Should You Choose?
• Best for device flexibility → Betron BS10. A 3.5mm jack covers phones, tablets, laptops and controllers; the CREHAO 2 is Lightning-only.
• Best for iPhone 14 and older → CREHAO 2. No adapter needed, and it's built around iOS compatibility.
• Best for battery-free, pairing-free listening → a tie, with a caveat. Both are fully wired, but only the BS10 works on non-Lightning gear.
• Best for bass-forward everyday listening → Betron BS10. Its 12mm dynamic drivers and low 16 ohm impedance are tuned for easy, bass-rich playback.
• Best for getting two pairs → CREHAO 2. It ships as a 2-pack; the BS10 is a single set with a storage pouch.
• Best warranty coverage → CREHAO 2. 18 months versus 12 months on the Betron.
• Best for mixed-device households or gaming → Betron BS10. Controllers, consoles and computers almost always use 3.5mm.
In my opinion, the Betron BS10 is the safer buy for most people, because a 3.5mm plug works with more of the devices you already own, and its easy-to-drive 12mm drivers plus inline volume control make it a genuinely convenient everyday pair. I'd pick the CREHAO 2 only if you're committed to an iPhone with a Lightning port and you like the idea of two pairs plus a longer 18-month warranty. If you're torn, decide on the connector first — that single detail settles it. Either way, check the current price on Amazon before you commit, since that's the one thing that can shift the math.
how to wired headphones work
Wired headphones carry an analog audio signal from your device through the cable to the drivers inside the earpieces, which convert it into sound. That's why they need no battery or Bluetooth pairing — the Betron BS10 and CREHAO 2 both work the moment you plug them in.
how to use wired headphones with iphone
On iPhone models with a Lightning port — the ones the CREHAO 2 supports, such as the 14, 13, 12, 11, XR and 8 — you plug the Lightning connector straight in. On newer iPhones without that port or a headphone jack, the Betron BS10's 3.5mm plug needs an adapter.
how to fix wired headphones no sound
Check the plug is fully seated, try a different device or port, and make sure the inline volume control isn't turned down. If only one side is silent, the cable or jack is usually the culprit — which is one practical argument for the CREHAO 2's two-pair pack.
do wired headphones need charging
No. Both the Betron BS10 and the CREHAO 2 are passive wired earphones, so there's no battery, no charging and no Bluetooth pairing involved — they run entirely off the audio signal from your device.
