How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired over-ear gaming headset built for streaming and long sessions, choose Astro Gaming A40; if you need a lightweight in-ear earphone for streaming on the move, choose Fezzlo Earphone Iris 2.0.
• Astro Gaming A40 — biggest strength: A full over-ear headset with ASTRO Audio V2 tuning, a swappable boom mic and a detachable cable system, which makes it the more natural fit for a desktop streaming setup.
• Astro Gaming A40 — biggest trade-off: It's a bulky over-ear design at 12.8 ounces, it's wired, and several of its best features (the closed-back Mod Kit) are sold separately.
• Fezzlo Earphone Iris 2.0 — biggest strength: A 40 g in-ear design with push-button media controls and sound isolation, so it disappears in your ears and travels easily.
• Fezzlo Earphone Iris 2.0 — biggest trade-off: It's an earphone, not a headset — the mic is inline on the cable, there's no boom arm, and it can't match the acoustic isolation a closed over-ear cup gives you.
• Choose Astro Gaming A40 if you stream or game at a desk and want a proper headset with a positionable boom mic.
• Choose Fezzlo Earphone Iris 2.0 if you stream light, travel, or want something you can wear for hours without a headband pressing on your skull.
The A40 TR is the classic wired gaming headset shape, and it's clearly designed around the desk-and-console gamer rather than the commuter. ASTRO Audio V2 is tuned specifically for gaming, which in practice means the tuning leans toward footsteps, gunfire and voice chat rather than a flat studio response. The frequency range runs a wide 10 Hz–32 kHz, and the dynamic drivers sit behind cloth ear cushions backed with synthetic leather — a combination that aims at comfort first and acoustic seal second.
For streaming, the interesting part is the microphone. It's a uni-directional boom mic that focuses on your voice and pushes background noise down, and it can be mounted on either side of the headset. That's a genuinely useful detail if your PC tower sits to one side of your desk, or if you like your mic on the left instead of the right. The headset terminates in a 3.5 mm jack, and the box includes a 1.5 m PC splitter, so you can separate headphone and mic signals on a desktop that has dedicated jacks. There's also a 1.0 m mobile cable for use with a phone or controller.
Who should skip it? Anyone who wants a headset that lives in a pocket. At 12.8 ounces with an over-the-head band, it's a stay-at-home piece of gear. It's also wired only — there's no wireless mode here, so if you want to walk around while listening, this isn't the tool.
Fezzlo Earphone Iris 2.0: Who It's For
The Iris 2.0 is a wired in-ear monitor-style earphone with a transparent PVC body and a soft, tangle-free cable built around high-purity oxygen-free copper conductors. It's 40 g total, and the ergonomic in-ear shape is the whole point: no headband, no clamping force, nothing sitting on top of your head. If you've ever finished a six-hour stream with a dent in your hair and hot ears, that difference matters more than any spec sheet line.
Sound-wise, Fezzlo describes it as warm and pure with heavy bass, driven by a dynamic driver, and the 64 ohm impedance is on the higher side for an earphone — which generally means it wants a bit of clean power from whatever it's plugged into rather than being driven by the weakest possible source. The 3.5 mm plug works with Android phones, PCs, MP3/MP4 players and music speakers. It also has inline push-button media controls and volume control on the cable, plus a mic, which is what makes it usable for streaming or calls at all.
The honest framing here: the mic is inline, not a boom. For a casual stream, a Discord call, or a quick voiceover, that's fine. For a main channel where your voice is the product, an inline mic picks up more room and sits closer to your chest than your mouth. The flip side is sound isolation — the in-ear seal blocks external noise, which helps you hear your own mix in a noisy room.
Skip it if you need a boom mic you can position, or if you want the wide soundstage an over-ear cup gives you for competitive shooters. Buy it if you stream from a laptop on a couch, travel, or just want something you can wear all day without noticing.

If I were building a streaming setup at a desk and my voice mattered, I'd buy the Astro Gaming A40. The boom mic that mounts on either side, the PC splitter in the box, and the option to convert it to a closed-back noise-isolating headset later give it a real upgrade path that an earphone simply can't offer. In my opinion the Iris 2.0 is the smarter pick only if your priority is wearing something weightless for hours and you're okay with an inline mic. If price is your deciding factor, check the current price on Amazon before you commit — the specs, not the number, are what should drive the choice.
Yes — it's built with a uni-directional boom mic that focuses on your voice and cuts background noise, and it can be mounted on either side. The included PC splitter makes it straightforward to run mic and audio separately on a desktop.
It works for gaming since it uses a standard 3.5 mm jack and a dynamic driver, but it's an in-ear earphone with an inline mic rather than a headset. It's best for casual play and streaming where you don't need a positionable boom.
The A40 TR is a 12.8 oz over-ear headset, so weight sits on your head; the Iris 2.0 is a 40 g in-ear with an ergonomic fit designed to avoid ear fatigue. Which one you prefer over a long session is mostly about whether you tolerate a headband or an in-ear seal.
The core headset, boom mic, Speaker Tags, mobile cable and PC splitter are included. The Mod Kit — synthetic leather noise-cancelling cushions, voice-isolating mic, padded headband and closed-back Speaker Tags — is sold separately if you want the closed-back configuration.
