If you want a complete, plug-in-and-go kit for late-night ghost-hunting sessions, choose Dunzy 2; if you need modern USB-C earbuds with an inline remote and a built-in mic for everyday phone, laptop, and tablet use, choose HAIMLJLBK USB C Headphones. These two look like they belong in the same search results, but they solve completely different problems. Here's how I'd split them.
• Dunzy 2 — biggest strength: It's a two-piece kit (wired headphones + black silk eye mask) built for paranormal investigation, with passive noise cancellation and a compact foldable design for storage.
• Dunzy 2 — biggest trade-off: The connection is a 3.5 mm jack, so it won't plug directly into USB-C-only phones, tablets, or laptops without an adapter.
• HAIMLJLBK USB C Headphones — biggest strength: Native USB-C plug-and-play with a DAC chip, inline volume/playback controls, and an HD microphone — a 2-pack, so you get a spare.
• HAIMLJLBK USB C Headphones — biggest trade-off: It's audio gear only — no eye mask, no session kit, nothing built around the ghost-hunting use case.
• Who Dunzy 2 is for: Buyers who want one box that covers an entire investigation session (listening + blindfold) and are working with a 3.5 mm source.
• Who HAIMLJLBK is for: Buyers who want modern USB-C earbuds for calls, music, meetings, and gaming on current phones and laptops — and want a second pair in the box.
The Dunzy 2 is a kit first and headphones second. What you're buying is a two-item setup: a pair of wired over-ear/in-ear headphones and a black silk eye mask, packaged together for what the product describes as ghost-hunting and investigation work. The eye mask is the tell — this isn't aimed at commuters. It's aimed at someone setting up a session in a dark room, at home, or outdoors, where blocking out light and outside noise actually matters.
On the audio side, the headphones use a dynamic driver with a 20Hz–20,000Hz frequency range and passive noise cancellation. Passive noise cancellation means the physical fit and materials do the blocking rather than electronics — no charging, no battery to manage, nothing to switch on. The ear enclosure is listed as over-ear with silk as the enclosure material, and the whole thing folds down to a compact size for storage. That foldability matters more than it sounds: gear that packs flat is gear you'll actually bring along instead of leaving in a drawer.
The catch is connectivity. These are 3.5 mm jack headphones. If your phone or laptop has a headphone jack, you're fine. If it's a USB-C-only device, you'll need an adapter, and that's a real friction point worth knowing before you buy. In my opinion, Dunzy 2 is the right pick if you want the whole session kit in one purchase and you're running a 3.5 mm source. Skip it if you specifically need USB-C, or if you want earbuds for calls and daily listening — that's not what this package is built to do.
The HAIMLJLBK set is the opposite philosophy: it's pure everyday audio gear, and it's built around USB-C. You get two pairs of in-ear earbuds in white and black, a USB-C connector, and plug-and-play performance with no Bluetooth pairing and no battery to think about. The product description emphasizes an advanced DAC chip for clear, balanced audio with enhanced bass and reduced distortion — the DAC is the part that makes USB-C audio work properly on phones that dropped the headphone jack.
The practical features are where this one earns its place. There's an inline remote for volume, playback, and call control, plus a built-in HD microphone for calls, video meetings, and gaming chat. The in-ear design isolates ambient noise passively, and the ergonomic fit is described as lightweight to reduce ear fatigue over long sessions. The cable is tangle-resistant, which is a small thing that matters a lot if these live in a bag or pocket.
Side-by-Side: Which Should You Choose?
• Best for ghost-hunting or investigation sessions → Dunzy 2. The bundled silk eye mask and compact foldable design are built for exactly that.
• Best for modern phones and laptops → HAIMLJLBK. Native USB-C with a DAC chip means no adapters and no Bluetooth lag.
• Best for calls and meetings → HAIMLJLBK. The HD microphone and inline remote cover voice pickup and volume/playback control.
• Best for a 3.5 mm source → Dunzy 2. If your device still has a headphone jack, the wired 3.5 mm connection is simple and interference-free.
• Best for a complete package → Dunzy 2. Two items in one box — headphones plus eye mask — versus earbuds only.
• Best for having a spare → HAIMLJLBK. It ships as a 2-pack, so you get a second pair.
• Best for long listening comfort → HAIMLJLBK. The lightweight ergonomic in-ear fit is designed to reduce ear fatigue.
• Best for a specific hobby setup → Dunzy 2. Nothing about HAIMLJLBK is tailored to investigation work.
If I were buying for myself, I'd pick the HAIMLJLBK USB C Headphones. In my opinion, USB-C plug-and-play, an inline remote, a built-in mic, and a second pair in the box cover far more of my actual daily use — calls, music, meetings, travel — than a hobby-specific kit would. I'd only flip to the Dunzy 2 if I specifically wanted the bundled eye mask and a foldable session setup, and I had a 3.5 mm device to plug into. Different tools, different jobs.
No. The Dunzy 2 headphones use a 3.5 mm jack. If your phone or laptop is USB-C only, you'll need an adapter to use them.
Yes — they're listed as compatible with iPhone 17/16/15 series, along with Samsung Galaxy S25/S24/S23, iPad Pro, MacBook, and USB-C devices generally.
The HAIMLJLBK set, clearly. It has a built-in HD microphone and an inline remote for volume, playback, and call control. The Dunzy 2 kit is oriented around listening during investigation sessions, not voice calls.
