We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want wireless freedom with a real over-ear listening experience you can fold up and carry, choose PowerLocus Over-Ear Headphones; if you need to switch audio back and forth between two wired sources or outputs, choose cooidea 3.5mm.
These two products are not rivals in the usual sense. One is a pair of Bluetooth over-ear headphones. The other is a tiny passive switch box that routes a 3.5mm signal. But shoppers comparing them are usually asking the same question: what is the cleanest way to move my audio from device to device? The answer depends on whether you want to replace your headphones or simply control which of them is playing.
• PowerLocus biggest strength: A complete, self-contained listening solution — over-ear drivers, a built-in mic, Bluetooth 5.3, plus wired 3.5mm and Micro SD/TF and FM options in one foldable package.
• PowerLocus biggest trade-off: It is a listening device, not a router. It switches between sources by pairing or unplugging, not by flipping a physical toggle.
• cooidea biggest strength: True hardware switching. A single toggle sends one 3.5mm signal to either of two outputs, or picks between two inputs, with no power, drivers, or apps.
• cooidea biggest trade-off: It makes no sound of its own and needs wired 3.5mm devices on both ends. Plug it into a phone with no headphone jack and it does nothing.
• Who PowerLocus is for: Anyone who wants one pair of comfortable over-ear headphones for travel, sport, calls, and everyday listening.
• Who cooidea is for: Anyone juggling two wired audio sources or two outputs — PC plus laptop, or headphones plus speakers — who wants instant switching.
The PowerLocus P2 is built around convenience. It uses 40mm dynamic drivers with 32 ohm impedance, a frequency range up to 20,000Hz, and 110dB sensitivity, so it is easy to drive and tuned toward a full, bass-forward sound. Connectivity is generous for a single product: Bluetooth 5.3 for wireless, a 3.5mm jack for wired listening, plus Micro SD/TF card and FM radio playback. That means you can keep using it even when the battery is drained or when you would rather not pair at all.
Comfort and portability are clearly the design priorities. The earcups use memory-protein foam with a leather finish, the headband stretches, and the whole thing folds. At 165g it stays light on the head, and the included leather carrying case protects it in a bag. Battery life is quoted at around 15 hours of music playback and 14–15 hours of talk time, with a 2.5-hour charge via USB-C. Bluetooth range is listed at 36 feet, so you can leave your phone on a desk and walk around a room.
The controls are touch-based media controls with sound isolation rather than active noise cancellation, and there is a noise-reduction microphone for hands-free calls. In my opinion, this is the pick for someone who wants one dependable pair of headphones for commuting, the gym, and calls, and who values being able to switch between wireless and wired depending on the situation. Skip it if your real problem is routing audio between two devices you already own — that is a different job.
The cooidea audio switcher is a problem-solver, not a listening device. It is a 40 x 38 x 10mm aluminum box that weighs about 13 grams and does exactly one thing: it moves a 3.5mm signal between ports. It supports TS, TRS, and TRRS connectors, including CTIA and OMTP standards, so it handles plain stereo cables, cables with a microphone, remote-control cables, and balanced headphones or AV cables. Gold-plated contacts and a low-impedance, full-signal switching design are aimed at keeping the signal clean and avoiding ground loop noise when multiple devices share a path.
It works in two directions. In 1-in-2-out mode, you plug your source into the common port and two outputs into the two channels, then toggle to choose which output plays — headphones or speakers, for example. In 2-in-1-out mode, you connect two sources to the two channels and your headphones to the common port, then toggle to choose which source you hear. There is no power supply, no battery, no USB, and no software. You flip the switch and the audio path changes.
This is the right tool if you keep a desktop and a laptop on the same desk, or if you want speakers and headphones sharing one output without crawling behind the machine to swap cables. It ships with a TPU audio cable, and the aluminum housing should hold up to daily desk use. The obvious limits: both ends must be wired 3.5mm, and it adds nothing to a purely wireless setup. Skip it if your devices have no headphone jack or if you want fewer cables, not more.
• Best for wireless listening anywhere → PowerLocus Over-Ear Headphones. Bluetooth 5.3 with a 36-foot range and roughly 15 hours of playback.
• Best for switching between two wired devices → cooidea 3.5mm. One toggle, no power, no drivers.
• Best for calls and hands-free use → PowerLocus. Built-in noise-reduction microphone with 14–15 hours of talk time.
• Best for sharing one output between headphones and speakers → cooidea. Use 1-in-2-out mode.
• Best for travel and portability → PowerLocus. It folds, weighs 165g, and comes with a leather case.
• Best for a fixed desk setup with multiple sources → cooidea. At 13g and 40 x 38 x 10mm it disappears next to a monitor.
• Best for flexibility in how you play audio → PowerLocus. Bluetooth, 3.5mm wired, Micro SD/TF, and FM all in one device.
• Best for zero setup and zero charging → cooidea. Fully passive, plug-and-play from the first second.
If I had to pick one, I would buy the PowerLocus Over-Ear Headphones. It solves the bigger, more everyday problem: it gives you a comfortable over-ear pair for music, calls, and travel, and its 3.5mm jack plus Bluetooth 5.3 means you are not locked into one way of listening. The cooidea switcher is genuinely clever and I recommend it without hesitation — but only as an add-on for people who already own wired headphones and speakers and want a fast way to move between them. It is a companion, not a replacement. If your goal is to stop swapping cables behind your desk, get the cooidea. If your goal is better sound on the move, get the PowerLocus.
FAQ
how to switch headphones between devices
how to switch headphones left right
Channel order is set by how the plug and cable are wired, not by the headphones themselves. A standard TRS or TRRS 3.5mm plug carries left and right on separate conductors, and the cooidea switcher passes that signal through unchanged — it switches which source or output is active, not which side plays. If your channels are reversed, the cause is upstream, in the cable or the source's settings.
how to switch headphones to headset windows 11
Windows 11 treats a headset and headphones as different output and input devices. Plug in a 3.5mm headset and pick it under Settings > System > Sound, or use the quick settings in the taskbar to choose the output. Bluetooth models such as the PowerLocus appear as a separate audio device once paired, and you select them the same way.
how to switch headphones to speakers on computer
You can do this in software by changing the default playback device in your operating system. If you would rather not touch settings every time, run the cooidea switcher in 1-in-2-out mode: connect the computer to the common port, then your headphones and speakers to the two channels, and flip the toggle to send audio to whichever you want.
