• V-Moda Forza Metallo in-Ear — biggest strength: a full in-ear headphone package: 5.8mm dynamic driver, Hi-Res Audio certification from the Japan Audio Society, a 3-button mic/remote for Android and Samsung devices, plus sport fins, ear hooks and eight pairs of ear tips.
• V-Moda Forza Metallo in-Ear — biggest trade-off: it is a wired 3.5mm headphone, so it needs a phone or player with a headphone jack (or an adapter) and it ties you to a cable — no true wireless freedom.
• BQEYZ 6.35mm — biggest strength: it solves one specific connection problem — converting a 4.4mm balanced jack into a 6.35mm plug so a headphone cable fits mixers, keyboards, amps, speakers and microphones.
• BQEYZ 6.35mm — biggest trade-off: it is an adapter, not a listening device. On its own it produces no sound, has no driver, no mic and no cable, so it cannot replace headphones.
• Who V-Moda Forza Metallo in-Ear is for: listeners who want one wired headset for music, calls and workouts.
• Who BQEYZ 6.35mm is for: anyone whose gear has mismatched 4.4mm and 6.35mm sockets.
The Forza Metallo is a metal-bodied in-ear headphone built around a 5.8mm dynamic driver with a stated frequency range of 20 Hz to 40,000 Hz and a low 14-ohm impedance. That low impedance matters in the real world: it means the headphone is easy to drive, so a phone, laptop or budget USB DAC should reach a usable volume without needing a dedicated headphone amp. The Hi-Res Audio certification from the Japan Audio Society points to the high-frequency extension above 40kHz that V-Moda targets with hires music sources.
Who should buy it: commuters, gym-goers and Android users who want one wired headset that handles music, calls and workouts, and who value sound isolation plus a physical remote over touch controls. Who should skip it: iPhone-first users who need a Lightning or USB-C connection, anyone who has fully moved to true wireless, and listeners who want a detachable cable or a balanced 4.4mm termination. It is also not the pick for someone who just needs to plug headphones into a studio console — that is a different problem entirely.
BQEYZ 6.35mm: Who It's For
The BQEYZ 6.35mm is an audio adapter, not a headphone. Its job is narrow and clear: it takes a 4.4mm jack and presents it as a 6.35mm plug, which is the large connector used on mixing consoles, digital pianos and keyboards, active amplifiers and speakers, electric guitars, condenser and dynamic microphones, and home Hi-Fi gear. If your headphone cable ends in a 4.4mm balanced plug and your device only offers a 6.35mm socket, this is the bridge between them.
The build is the selling point. BQEYZ describes a composite of aerospace-grade aluminum alloy, pure copper with thick gold plating, and a skin-friendly PC soft resin shell. The gold plating is there for corrosion resistance and a stable contact surface, while the metal body is meant to resist drops and wear and to shield against external electromagnetic interference. The short-angle plug design is a practical touch too — it keeps the adapter from jutting far out of a socket, which reduces leverage on the jack and makes plugging in and out smooth rather than sticky. BQEYZ also claims signal transmission loss as low as 0.01%, which is their way of saying the adapter is designed to stay out of the way of the signal rather than color it.
Who should buy it: musicians, home-studio owners, keyboard players and Hi-Fi listeners who already own 4.4mm cables or 4.4mm-terminated headphones and need them to fit 6.35mm equipment. It is also handy as a spare in a gig bag. Who should skip it: anyone shopping for actual earphones, anyone with a 3.5mm-only setup, and anyone who needs a mic, remote or wireless connection — this adapter has none of those. Note that it is a passive adapter with no plug of its own, so it only works when paired with a compatible 4.4mm cable.
Side-by-Side: Which Should You Choose?
• Best for phone calls and voice assistants → V-Moda Forza Metallo in-Ear. Its 3-button remote and mic are built for Samsung and Android devices.
• Best for workouts and sweat → V-Moda Forza Metallo in-Ear. Detachable sport fins in three sizes, sport ear hooks and weather/sweat resistance round it out.
• Best for connecting a 4.4mm headphone to a mixing console, piano or amp → BQEYZ 6.35mm. That is precisely what it is engineered for.
• Best for a pro-audio or home-studio setup → BQEYZ 6.35mm. Gold-plated contacts and an aluminum/copper body suit frequent plugging and unplugging.
• Best for travel and portability → BQEYZ 6.35mm. At 13 g and pocket-sized, it disappears into a gig bag; the V-Moda is a full headphone kit with a case.
• Best for Android users who want one do-everything wired headset → V-Moda Forza Metallo in-Ear.
• Best for iPhone or USB-C-only users → neither as-is. The V-Moda terminates in 3.5mm, and the BQEYZ is a 4.4mm-to-6.35mm adapter, so you would need a separate solution.
For most people reading this comparison, I would buy the V-Moda Forza Metallo in-Ear. It is the only one of the two that is actually a listening product, and it covers a huge amount of ground: Hi-Res-certified sound, a mic and remote for Android, sport fins and hooks for the gym, and a genuinely generous accessory set including eight pairs of ear tips and a carrying pouch. In my opinion the BQEYZ 6.35mm is excellent at what it does, but what it does is one job — adapting a 4.4mm cable to a 6.35mm socket. If you own studio or stage gear with a 6.35mm input, buy it without hesitation. If you are shopping for earphones, the V-Moda is the answer. Check the current price on Amazon before you commit, since both are inexpensive enough that the decision should come down to the job, not the number.
No. It is a wired in-ear headphone with a 3.5mm jack. The listing notes Bluetooth under connectivity technology, but the product itself connects via the DiamondBack cable and a 3.5mm plug for audio and the 3-button remote.
It converts a 4.4mm jack into a 6.35mm plug so 4.4mm cables or headphones can connect to mixing consoles, digital pianos, amplifiers, speakers, guitars and microphones. It is passive and needs a compatible 4.4mm cable to work.
No. It has no driver, no cable and no microphone. It is purely a connector, so it cannot produce sound on its own.
The V-Moda Forza Metallo in-Ear. It comes with detachable ActiveFlex sport fins in three sizes, sport ear hooks and a sweat- and weather-resistant build, none of which an adapter offers.
