Heil Sound Pro Set 3 vs StreamEye Focusrite Scarlett 2i2 at a Glance
• Biggest strength, Heil Sound Pro Set 3: three detachable twist-lock cables — a 1.8 m straight, a 1.8 m straight with a phone-compatible 3.5 mm plug, and a 3 m coil — all terminating in a gold-plated screw-on 1/8″-to-1/4″ adapter. One headphone, every jack you own.
• Biggest trade-off, Heil Sound Pro Set 3: it's monitoring only. No mic input, no preamp, no XLR, nothing that lets you record anything.
• Biggest strength, StreamEye Focusrite Scarlett 2i2: a complete signal chain in one box — the Scarlett 2i2 (4th Gen) with two combo XLR/TRS inputs and 69 dB of gain, Cans50 closed-back headphones, plus a 10-foot and a 25-foot XLR cable.
• Biggest trade-off, StreamEye Focusrite Scarlett 2i2: you're buying a system, not a headphone. Without a microphone and a USB-C computer the interface does nothing, and the headphones are whatever the bundle includes rather than the pair you'd have picked.
• Buy Heil Sound Pro Set 3 if your sources are already sorted and you just need to hear them clearly — editing, monitoring, remote calls, quiet listening.
• Buy StreamEye Focusrite Scarlett 2i2 if hearing isn't your problem. Recording is.
Start with the load. The Pro Set 3 is a closed-back over-ear with a 32-ohm impedance rating, 102 dB sensitivity, neodymium dynamic drivers and a 10 Hz–22 kHz frequency response, with a 1,000 mW maximum input. That 32-ohm figure is the one that matters most for laptop work: low-impedance, high-sensitivity headphones are easy for a modest onboard headphone amp to drive to a decent level, so you're not dependent on a separate amp to get usable volume from a 3.5 mm jack. The closed-back enclosure and the sound-isolation spec are what make it practical in a shared room or a noisy café — the outside world gets pushed back, and what you're listening to stays mostly yours.
The cable system is the part I'd actually pay attention to. Three detachable leads, all twist-lock so they don't yank loose mid-session: a 1.8 m straight cable, a second 1.8 m straight cable with a mating iPhone/iPod-compatible 3.5 mm plug, and a 3 m coiled cord. Every one of them terminates in an 1/8″ gold-plated connector with a screw-on 1/4″ adapter, so the same headphone moves between a laptop, a portable player and a piece of gear with a 6.35 mm jack without you digging through a drawer. There's a cable-mounted volume control, a protective case in the box and a one-year warranty. At 16 ounces it's a substantial over-ear, in a metal-and-plastic build, and Heil pitches it as a lightweight professional headset you can wear for hours without the fatigue that heavier closed-backs cause.

Who should buy it: the person whose work is listening. Someone editing a podcast on a laptop, logging audio, doing remote voice calls, running live-sound monitors, or wanting one dependable closed-back pair for broadcast-style playback. Who should skip it: anyone who needs to capture a mic signal, because there's no input path here at all. And if you were expecting a broadcast headset with a boom mic, read the sheet carefully — this is listed as headphones, with ear cushions, headband, case and cables, and nothing else.
This bundle is built around a job, not a component. The core is the Focusrite Scarlett 2i2 (4th Gen), a class-compliant USB-C interface with two combo XLR/TRS inputs, 24-bit/192 kHz conversion and 69 dB of preamp gain — enough range to lift a low-output dynamic mic to a healthy level. Around it: a pair of Cans50 closed-back headphones, a 10-foot SSAV XLR cable and a 25-foot Calrad XLR cable. The logic is straightforward. An interface by itself leaves you with nothing to monitor on and no way to reach a mic, so StreamEye filled both gaps in one purchase.
The 2i2's feature set is where the bundle earns its keep for beginners. Auto Gain runs a 10-second test pass and sets the input level for you. Clip Safe samples 96,000 times a second and pulls gain back before a take gets ruined, while the Dynamic Gain Halos flash red as you approach the edge. Air mode adds Presence and Harmonic Drive on each channel independently, so a vocal and an acoustic guitar tracked at the same time can each get different treatment. There are hi-Z instrument inputs for plugging a guitar in directly, phantom power for condenser mics, and line and headphone outputs. Being class-compliant over USB-C means no drivers — it shows up as the audio device on Mac, Windows and USB-C tablets, and it takes any standard XLR microphone or instrument jack.
The Cans50 is closed-back circumaural with 50 mm dynamic drivers, a 15 Hz–25 kHz response and 32-ohm impedance — again, easy to drive straight from the interface's headphone output, which is exactly the point. The 90-degree fold-flat earcups and the included soft bag are there for packing it up, and there's a 1/4-inch adapter. The two cables are balanced 3-pin male-to-female with twisted-pair shielded conductors, so common-mode rejection does its job over the long 25-foot run into a vocal booth or a far corner of a room.
Who should buy it: the home recordist, podcaster, singer-songwriter or voice-over artist starting from zero, with a mic and a modern computer and no interface yet. Who should skip it: anyone who only needs headphones, anyone who already owns an interface and a pair of tracking cans, and anyone whose laptop has no USB-C port — check your machine's connections before you commit, because the interface end is USB-C.
• Best for plugging straight into a laptop headphone jack → Heil Sound Pro Set 3. 32 ohms, 102 dB, and the 3.5 mm cable is already in the box.
• Best for actually recording a vocal or guitar into a laptop → StreamEye Focusrite Scarlett 2i2. Two preamps, 69 dB of gain, phantom power and instrument inputs.
• Best for cable flexibility across jack sizes → Heil Sound Pro Set 3. Three detachable leads plus a screw-on 1/8″-to-1/4″ adapter beats a single headphone cable.
• Best for first-take levels without an engineer → StreamEye Focusrite Scarlett 2i2. Auto Gain, Clip Safe and the gain halos are built for people recording alone.
• Best for long mic runs without hum → StreamEye Focusrite Scarlett 2i2. The 25-foot balanced, shielded XLR cable is the reason that bundle includes two lengths.
• Best for isolation while tracking to a click → both are closed-back, but I'd give the edge to the Cans50 for tracking because of the fold-flat circumaural design; the Heil is the one I'd pick for wearing through a four-hour editing block.
• Best if you already own an interface → Heil Sound Pro Set 3. Adding a second interface buys you nothing.
• Best single purchase for a first home studio → StreamEye Focusrite Scarlett 2i2. One box, plug in, start tracking.
My Verdict
FAQ
No. It's rated at 32 ohms with 102 dB sensitivity, and a 3.5 mm cable plus a screw-on 1/4″ adapter are included — plug it into the laptop's headphone output and it works.
Both are closed-back. If you were searching for open ear headphones for laptop use, neither of these is that design — and for laptop work in a shared space, closed-back isolation is usually the better trade anyway.
The sheets don't list rotating cups or specify memory foam cushions for either pair. The Cans50 does list 90-degree fold-flat earcups, which is a packing feature rather than a swivel, and the Heil lists ear cushions in the box without naming the foam. Don't buy on the assumption.
That depends on what you'd otherwise have to buy. The Heil covers one job completely; the StreamEye bundle covers an interface, a headphone and two cables in one go — so if you need all three, it's the more efficient purchase, and if you need only the first, it's money spent on gear you won't use. Check the current price on Amazon for both before you decide.
