If you want a drop-in replacement boom mic for an Astro A40 or A40 TR headset, choose weishan A40; if you need a replacement mic for a JBL Quantum 100-series headset, choose NewTH Replacement Game Microphone. These two look almost identical in photos, but the connector and the headset they fit are completely different — and that single detail decides everything.
• weishan A40 biggest strength: a 3.5 mm gold-plated plug and a bendable metal-hose boom built specifically for Astro A40 / A40 TR headsets, with a 1-year replacement warranty.
• weishan A40 biggest trade-off: it only fits Astro A40-family headsets — plug it into a JBL Quantum and it simply won't work.
• NewTH biggest strength: a 2.5 mm gold-plated plug molded 1:1 to the JBL Quantum 100 / 350 / 100P / 100X / 360P socket, plus a spare foam cover and a 2-year manufacturer warranty.
• NewTH biggest trade-off: it's locked to those JBL Quantum models — it will not fit an Astro A40, and NewTH states this plainly.
• Who each pick is for: Astro A40 owners → weishan A40. JBL Quantum 100-series owners → NewTH.
The weishan A40 is a single-purpose part: a detachable boom mic that replaces a broken or lost microphone on an Astro A40 or A40 TR gaming headset. It's a unidirectional mic with a 3.5 mm jack, so it's designed for the Astro connection standard and for the consoles and devices Astro owners actually use — PS5, PS4, Xbox, PC, Mac and phones. Nothing here is universal, and that's the point. If your Astro mic died, this is the shape and plug your headset expects.
What it does best is the mechanical stuff. The boom runs on a bendable metal hose covered in soft silicone, so you can push the mic close to your mouth and it holds that position instead of sagging back. weishan lists a 7-inch (18 cm) length and a 360-degree flexible neck, which is exactly the range you want for fine-tuning mic placement. The gold-plated plug is there to reduce signal loss, and the foam windscreen filters breath and plosives while keeping dust and moisture off the element. Signal-to-noise ratio is listed at 78 dB, frequency response tops out at 20 kHz, and it's a single-channel wired mic that runs on battery power. It ships with one black foam cover and a 1-year replacement warranty.
Who should buy it: anyone with an Astro A40 or A40 TR whose stock mic is lost, chewed up, or crackling, and who wants a like-for-like swap without buying a whole new headset. Who should skip it: anyone with a JBL, SteelSeries, HyperX or other headset — the 3.5 mm Astro-style plug won't seat correctly, and no amount of bending will fix a wrong connector. If you're not on an Astro A40, this is not your part.
NewTH's mic is the mirror image of the weishan. It's built for JBL Quantum 100 (Q100), 350, 100P, 100X and 360P headsets, and NewTH is upfront that it won't work on any other model. The connector is a 2.5 mm gold-plated jack, which is the smaller plug JBL uses on these headsets — not the 3.5 mm you'll find on an Astro. If you're holding a JBL Quantum with a dead boom, this is the part designed for that socket.
The feature list is aimed at daily gaming and streaming. NewTH describes a 1:1 molded fit against the original headset, a soft bendable boom that moves 360 degrees and stays put, and a unidirectional capsule with the same 78 dB signal-to-noise ratio as the weishan. The plug is gold-plated copper for anti-oxidation, the head is ABS plastic, and there's a built-in pop filter behind a stainless windscreen. Cable length is 6.5 inches — NewTH calls that "exactly the right length to reach your mouth," and it's a sensible figure for a boom this size. Impedance is listed at 45 ohm, and it's a wired, corded-electric mic with no batteries and no drivers. You also get a second foam cover as a spare, and a 2-year manufacturer warranty.
Who should buy it: JBL Quantum 100-series owners who want a cheap, plug-and-play replacement and value the spare foam and longer warranty. Who should skip it: Astro A40 owners, and anyone with a headset outside the JBL Quantum list — the 2.5 mm plug is narrower than a standard 3.5 mm, so it won't fit most other headsets either.
• Best for Astro A40 / A40 TR owners → weishan A40. It's the only one of the two with the correct 3.5 mm plug and Astro-specific fit.
• Best for JBL Quantum 100 / 350 / 100P / 100X / 360P owners → NewTH. The 2.5 mm plug and 1:1 molded fit are made for those sockets.
• Best for a longer boom and closer mouth placement → weishan A40. Listed at 7.09 inches with a silicone-covered bendable metal hose.
• Best for spare parts and warranty coverage → NewTH. It ships with an extra foam cover and a 2-year manufacturer warranty versus 1 year on the weishan.
• Best for durability of the boom material → weishan A40. The metal-hose core inside silicone is a sturdier feel than NewTH's soft ABS-and-silicone boom, though both are stated as bendable 360 degrees.
• Best for plug-and-play simplicity → tie. Neither needs drivers or batteries; both are wired single-channel mics with a 78 dB signal-to-noise ratio.
• Best for streaming and recording use → NewTH. NewTH explicitly lists streaming, karaoke and video conference among its use cases, and the noise-cancelling claim is emphasized more heavily.
• Wrong connector = wrong product. Buy by headset model first, features second. That's the whole decision here.
In my opinion, the spec sheets make this a two-lane choice rather than a real head-to-head. If you own an Astro A40 or A40 TR, I'd buy the weishan A40 — the 3.5 mm plug, the metal-hose boom and the Astro-specific fit are exactly what that headset needs, and the 1-year replacement warranty covers the obvious failure point. If you own a JBL Quantum 100-series, I'd buy the NewTH — the 2.5 mm plug is non-negotiable, and the extra foam cover plus 2-year warranty make it the more complete package. Neither is "better" in the abstract. One fits Astro, one fits JBL.
FAQ
weishan A40. It has the 3.5 mm plug and Astro A40 / A40 TR fit, and it's listed for PS5, PS4, Xbox, PC, Mac and phone through that headset. The NewTH uses a 2.5 mm plug and is explicitly for JBL Quantum models only, so it won't fit an Astro.
Yes — NewTH lists the Quantum 100 (Q100), 350, 100P, 100X and 360P as compatible, and states it will not work on any other headset. It's a 2.5 mm gold-plated jack, so check your headset's socket size before ordering.
The NewTH is corded electric with no batteries and no drivers — plug and play. The weishan is listed as battery powered, which reflects how the Astro headset supplies the mic through its connection, not a separate battery you install.
Match the connector to your headset first. Astro A40 family → 3.5 mm → weishan A40. JBL Quantum 100-series → 2.5 mm → NewTH. Then check the current price on Amazon using the button on this page, since both are inexpensive replacement parts and the value call is yours to make.
