If you want one pair of over-ear headphones that works wirelessly over Bluetooth and also over a plain 3.5mm aux cord, choose PowerLocus Over-Ear Headphones; if you need a single replacement aux cable to revive a pair of Bose or JBL headphones that already has a detachable 2.5mm socket, choose Callez Replacement Audio Cable.
• PowerLocus Over-Ear Headphones — biggest strength: it's a complete, self-contained pair of 40mm over-ear headphones with Bluetooth 5.3, a 15-hour battery, a built-in mic, and a 3.5mm jack for wired listening when the battery runs out.
• PowerLocus Over-Ear Headphones — biggest trade-off: it's a budget-class wireless headphone, so it gives you convenience and flexibility rather than reference-grade audio, and the mic is a call mic, not a gaming headset boom.
• Callez Replacement Audio Cable — biggest strength: it's a purpose-built 2.5mm-to-3.5mm aux cable with a 24K gold-plated straight plug and oxygen-free copper wiring, designed specifically to replace the cord on Bose 700/QC25/QC35/QC45 and JBL Tune 660NC/710BT/760NC headphones.
• Callez Replacement Audio Cable — biggest trade-off: it only fits headphones with a 2.5mm jack port on the earcup, it carries no microphone and no volume control, and it will not work with Beats or Sennheiser headphones.
• Who each pick is for: PowerLocus is for the person who wants one headphone for everything — commuting, travel, kids' tablets, phone calls, wired or wireless. Callez is for the person who already owns a compatible Bose or JBL headphone and just needs the cord to work again.
The PowerLocus P2 is the "one pair does everything" answer. It's an over-ear headphone with 40mm dynamic drivers, a 32-ohm impedance rating, and a frequency range that reaches up to 20,000 Hz. It streams over Bluetooth 5.3 with a stated range of around 36 feet, and it charges over USB-C in roughly 2.5 hours. The battery is rated at about 15 hours of music playback and 14–15 hours of talk time, which is enough for a full week of short commutes or a long-haul flight.
What makes it genuinely flexible is that it isn't wireless-only. There's a 3.5mm jack on board, and the box includes a cable, a protective case, and the charging cable. So if the battery dies mid-flight, or you want to plug straight into a laptop, a Nintendo Switch, an in-flight entertainment system, or an older phone with a headphone jack, you just run it wired. That's the whole reason this pair is worth considering alongside a bare replacement cable: it covers both scenarios out of the box.
Who should buy it: travelers, students, commuters, and parents buying for teens who want one headphone that pairs with an iPhone, a Samsung, an iPad, an Amazon Fire tablet, or a PC, and that still works when the battery is flat. Who should skip it: anyone who needs true active noise cancelling, a boom mic for competitive gaming, or audiophile-grade tuning. In my opinion, this is a convenience-first headphone, and it should be judged that way.
Callez Replacement Audio Cable: Who It's For
The Callez cable solves a much narrower problem, and it solves it well. It's a male-to-male aux cord: 2.5mm on one end that plugs into the headphone earcup, and a standard 3.5mm on the other end that plugs into your phone, laptop, tablet, console controller, or anything else with a normal headphone jack. It's about 4.99 ft / 152cm long, black, and built from TPE with a 24K gold-plated straight plug and oxygen-free copper conductors that resist electromagnetic and radio-frequency interference.
The critical detail is the 2.5mm end. This cable is made for headphones that use a 2.5mm socket on the earcup — specifically Bose 700 (NC700), QuietComfort 25, QC35, QC35II, QC45, JBL Tune 660NC, 710BT and 760NC, and AKG Y40 / N700NC. If your headphone has a 3.5mm socket on the cup, this is the wrong cable. It also explicitly does not fit Beats or Sennheiser headphones, so check your model before ordering.
The other thing to know up front: there's no inline microphone and no volume control on this cord. If you're replacing a Bose cable that had a mic module and you take a lot of calls, you'll lose that function and will need to talk through the device itself or a different cable. On the plus side, the straight plug design and soft, tangle-resistant TPE jacket make it easy to coil and carry, and plug-and-play means no pairing, no charging, and no battery anxiety — it just works as long as the source has a 3.5mm jack.
Who should buy it: anyone whose Bose or JBL headphone still sounds great but whose original cord is frayed, lost, or intermittent. Who should skip it: owners of Beats, Sennheiser, or 3.5mm-socket headphones, and anyone who needs an inline mic.
Side-by-Side: Which Should You Choose?
• Best for reviving a headphone you already love → Callez Replacement Audio Cable. It exists purely to replace a broken Bose/JBL-style cord.
• Best for battery-free, zero-latency listening → Callez Replacement Audio Cable. A passive cable has no battery, no pairing, and no charging delay.
• Best for travel and everyday commuting → PowerLocus Over-Ear Headphones. Foldable, ~150–165g, 15-hour battery, and a protective case included.
• Best for kids, tablets and mixed devices → PowerLocus Over-Ear Headphones. It pairs with iPhone, Samsung, iPad, Amazon Fire tablet and PC, and works wired for anything else.
• Best for calls and hands-free talk → PowerLocus Over-Ear Headphones. It has a built-in noise-reduction microphone; the Callez cable has no mic at all.
• Best for a specific headphone model (Bose 700/QC25/QC35/QC45, JBL Tune, AKG) → Callez Replacement Audio Cable. Compatibility is model-specific by design.
• Best if you want one purchase that covers most situations → PowerLocus Over-Ear Headphones. Fewer moving parts, one box, both connection types.
In my opinion, most people reading this should buy the PowerLocus Over-Ear Headphones. It's the only one of the two that works on its own — Bluetooth when you want freedom, a 3.5mm cable when you don't — and it comes with everything needed to start listening. I'd only pick the Callez Replacement Audio Cable if you already own a compatible Bose, JBL or AKG headphone with a 2.5mm cup socket and simply need to replace the cord. That's a repair, not an upgrade. Buy the Callez cable to fix what you have; buy the PowerLocus to get something new that does both wired and wireless.
how to make aux cable with headphones
You don't actually need to "make" anything — you need a headphone with a 3.5mm jack, or a replacement cable like the Callez that converts a 2.5mm earcup socket to a standard 3.5mm plug. The PowerLocus headphones already include a 3.5mm cable in the box, so you can go wired immediately. Just match the plug size on the headphone end to the socket on the headphone.
how to use wired headphones without headphone jack
how do i connect my wired headphones to my phone
Plug the 3.5mm end of the cable into the phone's headphone jack, and the 2.5mm end into the headphone's cup socket if that's the model you own. If there's no jack on the phone, use the correct adapter for your charging port. Note that the Callez cable is audio-only — it has no microphone or volume control, so calls go through the phone itself.
does this cable work with all Bose headphones?
No. The Callez cable is only for models with a 2.5mm jack port, and it lists Bose 700 (NC700), QuietComfort 25, QC35, QC35II and QC45, plus JBL Tune 660NC/710BT/760NC and AKG Y40/N700NC. It is explicitly not for Beats or Sennheiser headphones. Check your exact model before ordering, and check the current price on Amazon using the button on this page.
