If you want a pair of wireless over-ear headphones you can fold up, wear for hours and use with almost any phone, tablet or PC, choose PowerLocus Over-Ear Headphones; if you need to repair the game card reader and headphone jack on an original Nintendo Switch console, choose MFLDSFLHM Switch Game Card.
• PowerLocus Over-Ear Headphones — biggest strength: a genuine all-rounder audio device — Bluetooth 5.3 wireless plus a 3.5 mm wired option, a built-in mic for calls, a 15-hour battery, foldable over-ear comfort and a protective carry case.
• PowerLocus Over-Ear Headphones — biggest trade-off: it's a consumer headphone, so it gives you music and calls, not precision hardware repair. If something inside it fails, you're not fixing it yourself.
• MFLDSFLHM Switch Game Card — biggest strength: it's a purpose-built replacement part that solves a very specific, very annoying console problem — no sound from the headphone port, a card reader that won't read or eject games.
• MFLDSFLHM Switch Game Card — biggest trade-off: it only fits the original Switch HAC-001 model, it explicitly does not fit Switch Lite or OLED, and it requires real repair experience — no install guide is included.
• Who each is for: PowerLocus is for anyone who wants to listen, talk and travel with one affordable-feeling headset. The MFLDSFLHM card is for a confident tinkerer reviving a broken original Switch.
Think of PowerLocus as the everyday listening tool in this comparison. It's an over-ear Bluetooth headphone with a 40 mm dynamic driver, 32 ohm impedance and a frequency response rated up to 20,000 Hz. In plain terms, that's a standard full-size headphone recipe: deep bass, dynamic sound and enough sensitivity (110 dB) to get loud without much effort. The sound-isolation design and memory-protein foam leather earcups are what make it wearable for long stretches rather than a five-minute novelty.
Buy it if you want one headphone for commuting, studying, gaming sessions on a phone or tablet, and hands-free calls — and you like the idea of folding it flat into the included leather case.
Skip it if you need studio-grade accuracy, active noise cancellation or a headphone you plan to repair rather than replace. This is a convenience-first design, and the foldable, stretchable frame is built to fit a wide range of head sizes — kids, teens and adults — rather than one perfect head.
MFLDSFLHM Switch Game Card: Who It's For
This is not a listening device at all, and that's the point. The MFLDSFLHM Switch Game Card is a replacement game card reader slot with an integrated headphone jack port, made for the original Nintendo Switch HAC-001 console only. It exists to fix a specific cluster of faults: no voice from the headphone port, a card reader that isn't detected, games that won't read, cards that won't insert or eject properly, or the console constantly re-loading a game.
The kit is practical for what it is. You get one set of the headphone jack and card reader slot replacement parts, eight back cover screws, pry tools and two screwdrivers. It's produced by a third-party factory and inspected before packing, and the listing notes it should match the original fit. Importantly, the job does not require desoldering or soldering — but it does require experience. There's no printed or video guide in the box, and you'll likely need to transfer some accessories over from your old console rather than getting a complete drop-in module.
Buy it if you own an original HAC-001 Switch, you're comfortable opening electronics, and you've already watched a headphone jack replacement video so you know what you're getting into.
Skip it if you have a Switch Lite or an OLED model — it will not fit — or if you'd rather not open your console at all. In that case, a professional repair is the better route.
• Best for listening to music, podcasts and calls → PowerLocus Over-Ear Headphones. It's the only one of the two that actually plays audio.
• Best for fixing a broken original Switch → MFLDSFLHM Switch Game Card. It's a repair part, and nothing else on this page is.
• Best for battery life → PowerLocus Over-Ear Headphones, with 15 hours of playback and about 14–15 hours of talk time per charge.
• Best for wired flexibility → PowerLocus Over-Ear Headphones, thanks to the 3.5 mm jack alongside Bluetooth 5.3.
• Best for travel → PowerLocus Over-Ear Headphones. Foldable, 165 g, and it ships with a leather protective case.
• Best for console compatibility caution → MFLDSFLHM Switch Game Card. Check your model first: HAC-001 only, not Lite, not OLED.
• Best for a no-soldering repair → MFLDSFLHM Switch Game Card, which the listing says needs no desoldering or soldering — just experience.
• Best for a low-effort purchase → PowerLocus Over-Ear Headphones. Charge it, pair it, wear it. No tools, no teardown.
In my opinion these two products don't compete for the same buyer at all — they compete for the same moment. If your Switch's headphone port or card reader has failed, the MFLDSFLHM part is the only one of the two that solves your problem, and I'd buy it if I owned an original HAC-001 and was comfortable doing the swap. For everyone else, I'd buy the PowerLocus Over-Ear Headphones: wireless and wired, a 15-hour battery, a mic for calls, a carry case and a foldable frame that fits most heads. One is a tool; the other is a daily companion. Pick the one that matches the job in front of you.
how to switch headphones left right
On most over-ear headphones — PowerLocus included — the left and right earcups are marked on the inside of each cup, and the headband is worn with the mic and controls on the appropriate side. If stereo channels feel reversed, flip the headset around rather than changing any setting; on a wired connection, also check that the 3.5 mm plug is fully seated.
how to switch headphones between devices
With PowerLocus, the simplest route is Bluetooth: turn the headphones off, then slide the power button to re-enter pairing mode and connect from the new device's Bluetooth menu. You can also skip Bluetooth entirely and use the 3.5 mm cable, which works with any device that has a headphone jack — no pairing required.
how to switch headphones to headset windows 11
Plug the 3.5 mm cable into your PC's headphone jack, or pair over Bluetooth, then open Windows 11 sound settings and set the PowerLocus as both the output and input device if you want to use the built-in mic for calls. If audio still routes to your speakers, select the headphones explicitly in the output dropdown.
how to switch headphones to speakers on computer
This is a Windows setting, not a headphone feature: open the sound output selector in the taskbar and choose your speakers instead of the headphones, and unplug the 3.5 mm cable if it's connected. On Bluetooth, disconnect or turn off the PowerLocus and Windows will fall back to the default speakers automatically.
