If you want a detachable boom mic that turns Bose QuietComfort 35 / QC35 II headphones into a proper gaming and voice-chat headset, choose weishan Detachable Mic; if you need a plug-and-play replacement for a lost or broken Razer Barracuda X microphone, choose LEFXMOPHY Mic Replacement. These two cables look similar on a listing page and get compared for one simple reason: both are small, black, detachable boom microphones. They are not interchangeable, though. The plug on the headphone end is different, the intended headset is different, and the feature set is different.
• weishan Detachable Mic — biggest strength: it converts QC35 / QC35 II headphones into a wired headset with a mute switch, a position-lock 2.5mm connector, a 4-foot cable, and a 3.5mm splitter adapter for devices that need separate mic and headphone jacks.
• weishan Detachable Mic — biggest trade-off: it is built around one narrow headphone family, and the 2.5mm-to-3.5mm cable plus splitter means more connections to manage than a single-plug mic.
• LEFXMOPHY Mic Replacement — biggest strength: a simple 3.5mm TR plug, a 5-inch (15 cm) bendable steel boom, foam cover, and a one-year warranty description — a straightforward swap for a Barracuda X mic that is lost or damaged.
• LEFXMOPHY Mic Replacement — biggest trade-off: it only fits the Razer Barracuda X, and it is an omnidirectional condenser design rather than a directional one, so it is less about isolating your voice and more about getting a working mic back on your headset.
• Who each pick is for: weishan for QC35 owners who want mute control and a longer cable; LEFXMOPHY for Barracuda X owners who just need the mic back.
The weishan Detachable Mic exists for one specific problem: you own Bose QuietComfort 35 or QC35 II headphones — including the gaming variants — and you want to use them for voice chat without buying a separate headset. The cable runs from a 2.5mm TRS plug into the headphone and ends in a 3.5mm TRRS plug for your device. That mismatch is deliberate. Bose's QC35 series uses a 2.5mm jack on the headphone side, so a normal 3.5mm boom mic simply will not seat properly. weishan's part number, QC35-Detachable-Mic-Cable, makes the intent plain.
Who should buy it: QC35 or QC35 II owners who want one cable that handles mic input, mute control, and connection to a console or PC, and who value the splitter adapter because their setup uses separate jacks. Who should skip it: anyone whose headset is not a QC35-series model — the 2.5mm headphone-side plug will not fit a standard 3.5mm microphone port, and this is not a universal mic.
LEFXMOPHY Mic Replacement: Who It's For
The LEFXMOPHY Mic Replacement is the opposite kind of product. It is not a conversion kit; it is a spare part. It is designed for the Razer Barracuda X Wireless Multi-Platform Gaming and Mobile Headset, and its whole job is to replace a microphone that has been lost, broken, or chewed on by a pet. LEFXMOPHY even describes it as an alternative accessory for a lost or broken microphone, which is about as honest as a product description gets.
The design is simple, and that is the point. One gold-plated 3.5mm TR plug goes straight into the Barracuda X. Plug and play — no adapter, no splitter, no extra cable to route. The boom is a 5-inch (15 cm) steel flexible hose that bends 360 degrees, so you can shape it toward your mouth and it should hold that shape. LEFXMOPHY lists a condenser omnidirectional polar pattern with noise cancellation and enhanced voice clarity, and a foam cover is included. Item weight is listed at 0.02 kg, so it will not add noticeable heft to the headset. The manufacturer also lists a one-year warranty description, which is more coverage than most small replacement parts carry.
Who should buy it: Barracuda X owners who need a working mic again, fast, without shopping for a whole new headset or a third-party boom that may not fit. Who should skip it: anyone who does not own a Barracuda X. This is not a universal 3.5mm boom mic for whatever headset you happen to have — it is cut for one model, and LEFXMOPHY says so directly.
Side-by-Side: Which Should You Choose?
• Best for Razer Barracuda X owners → LEFXMOPHY Mic Replacement. Single 3.5mm plug, no adapter, direct replacement.
• Best for mute control → weishan Detachable Mic. The inline mute switch button is a feature the LEFXMOPHY does not list.
• Best for a simple, no-adapter setup → LEFXMOPHY Mic Replacement. One plug, into one port, done.
• Best for directional voice pickup → weishan Detachable Mic. It uses a unidirectional cardioid element, which by design favors the sound in front of the mic; the LEFXMOPHY is omnidirectional.
• Best for reaching across a desk setup or console → weishan Detachable Mic. Its 4-foot cable gives you far more slack than a 5-inch boom alone.
• Best for flexible boom positioning → LEFXMOPHY Mic Replacement. A 360-degree bendable steel hose is explicitly designed to be shaped and reshaped.
• Best for extra connection hardware → weishan Detachable Mic. The included 3.5mm 1-to-2 splitter adapter matters if your PC has separate mic and headphone jacks.
• Best for warranty coverage → LEFXMOPHY Mic Replacement. A one-year warranty description is listed; weishan does not list one.
If I owned QC35 or QC35 II headphones and wanted to game or take calls with them, I would buy the weishan Detachable Mic. In my opinion it is the more complete product: the 2.5mm-to-3.5mm cable is the piece that actually makes those Bose headphones work as a wired headset, and the mute switch, splitter adapter, and cardioid element all earn their place in a real setup. If I owned a Razer Barracuda X and the mic had gone missing or stopped working, I would buy the LEFXMOPHY Mic Replacement instead — it is the simpler, more direct fix for that exact problem. Neither is a universal mic. Match it to your headset and you will be happy; mismatch it and no amount of adjusting will help.
FAQ
Yes — it is made specifically for the Razer Barracuda X Wireless Multi-Platform Gaming and Mobile Headset and uses a gold-plated 3.5mm TR plug. It is not intended for other Razer models or other brands.
weishan uses a unidirectional cardioid element, which is designed to pick up sound mainly from the direction it points. LEFXMOPHY uses an omnidirectional condenser, which picks up from all around. For isolating your voice in a noisy room, directional is generally the better choice by design.
