How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want certified hearing protection with Bluetooth audio for loud job sites, choose ISOtunes Link; if you need a dedicated office headset that makes your voice sound clear on calls, choose LEVN Headset. These two products look similar in a search bar, but they solve completely different problems. One is ear protection that happens to play music. The other is a call tool that happens to be wireless.
• ISOtunes Link's biggest strength: a 25 dB NRR physical barrier that blocks loud machinery, plus up to 50 hours of audio per charge and an optional AAA backup good for roughly 100 more hours.
• ISOtunes Link's biggest trade-off: it is built for protection first, so it has no boom mic for your voice, no charging base, and it does nothing for office chatter beyond physically covering your ears.
• LEVN Headset's biggest strength: a dual-mic array with an intelligent voice algorithm and a one-tap mute button, so people on the other end of your call hear you, not your background.
• LEVN Headset's biggest trade-off: it is not hearing protection. There is no noise reduction rating here, and on-ear cups with a 30 mm driver simply don't seal out a mower or a chop saw.
• Choose ISOtunes Link if you work in noise — construction, landscaping, a shop floor, a mower — and want to stay connected while your ears stay safe.
• Choose LEVN Headset if you live on calls — call center, remote office, back-to-back meetings — and your problem is how you sound, not how loud it is around you.
The LINK 2.0 is, at its core, a pair of over-ear earmuffs. That's the part people skip past. It carries an ANSI-certified 25 dB NRR and is OSHA compliant, which means it reduces noise by physically blocking it with the ear cup and foam cushion rather than by generating an inverse sound wave. ISOtunes calls this noise isolation, and it's a meaningful distinction: it works whether the headset is powered on or not.
The build is aimed at abuse. Foldable frame, IPX4 water and sweat resistance, and raised buttons designed so you can control playback with gloves on. It's orange, it's chunky, and it looks like equipment because it is equipment. SafeMax technology caps audio output at 85 dB so you can't accidentally crank music loud enough to undo the protection you're wearing.
Buy it if you're mowing, framing, running equipment, or working anywhere you'd otherwise reach for foam plugs — and you want music and calls in the same package. Skip it if your actual problem is that coworkers can't hear you on Zoom. There's no boom mic, no dongle, and no desktop charging base. It's also over-ear with a padded headband and a fairly substantial 0.56 kg weight, which is fine for a job site and overkill for a cubicle.
LEVN Headset: Who It's For
The LEVN HS010 Sup Pro is the mirror image. It's a work headset, and every design choice points at voice quality. A high-sensitivity dual mic array paired with an intelligent voice algorithm separates your voice from ambient noise — the company leans on this to handle open offices, busy homes, and cafes. There's a one-touch mute button for instant privacy, which is the feature people only appreciate after an embarrassing hot-mic moment.
Connectivity is genuinely flexible, and this is where LEVN earns its place. Plug-and-play USB dongle for laptops and desktops without Bluetooth, plus independent Bluetooth 5.2 pairing for phones and tablets. The dongle route matters more than it sounds: it sidesteps the pairing friction that makes people give up on wireless headsets at work. Range is listed at 33 feet (15 meters), enough to walk to a printer or grab coffee mid-call.
Buy it if you're on Teams, Zoom, or a call queue all day and need to sound professional. Skip it if you need actual hearing protection. There's no NRR, no OSHA certification, and on-ear cups with a 30 mm driver won't seal out real noise.
Side-by-Side: Which Should You Choose?
• Best for hearing protection → ISOtunes Link. A 25 dB NRR ANSI-certified rating is the whole point, and LEVN has nothing comparable.
• Best for being heard on calls → LEVN Headset. Dual mics plus a voice algorithm plus one-tap mute is a call-center toolkit; ISOtunes has no boom mic at all.
• Best for battery redundancy → ISOtunes Link. 50 hours rechargeable plus roughly 100 more from AAA backup beats 45 hours with no backup option.
• Best for desk and laptop setups → LEVN Headset. The USB dongle and charging base are built for a workstation; ISOtunes is Bluetooth-only.
• Best for loud environments → ISOtunes Link. IPX4, foldable, glove-friendly raised buttons, and a rugged frame made for mowing and construction.
• Best for all-day comfort in an office → LEVN Headset. On-ear sponge and leather cups at a lighter footprint suit long meetings better than heavy over-ear muffs.
• Best for wearing on either ear → LEVN Headset. The 270° rotatable mic adjusts for left or right side; ISOtunes is a fixed over-ear design.
• Best for a mixed job site and phone call → ISOtunes Link. Bluetooth 5.0 handles calls, just without voice isolation for the listener.
If I had to pick one, I'd buy the ISOtunes Link. In my opinion, protection is the harder problem to solve — you can't add a 25 dB NRR to a headset after the fact, but you can absolutely work around a missing boom mic by holding your phone or stepping somewhere quieter. The AAA backup alone makes it the safer bet for a full shift. That said, if your day is meetings rather than machinery, the LEVN Headset is the right tool and I'd recommend it without hesitation for that job. They're not really competitors — they're answers to two different questions. Check the current price on Amazon for whichever problem is actually yours.
Yes, it connects over Bluetooth 5.0 for two-way communication, but it has no boom microphone and no voice-isolation processing. Callers hear you through the headset's mic, so it works best in moderately quiet moments rather than a noisy shop floor.
No. It offers environmental noise cancellation for call audio and dual-mic noise suppression for your voice, but there is no NRR or OSHA certification. It reduces what the other person hears, not what reaches your ears.
Yes — that's what the USB dongle is for. Plug it in and it works without pairing. Bluetooth 5.2 is there as a second option for phones and tablets that have no USB port.
ISOtunes Link is rated for 50 hours of audio plus roughly 100 extra hours from an optional AAA battery. LEVN Headset is rated for up to 45 hours of talk time. ISOtunes wins on raw endurance and on having a backup at all.
