• Mr Rex 2.5mm — biggest strength: It revives headphones you already own. A 2.5mm plug on one end, a 3.5mm angled jack on the other, plus an inline mic and volume control, so your Bose 700, QC45, QC35II, QC35 or QC25 (and a long list of JBL and AKG models) becomes a wired headset.
• Mr Rex 2.5mm — biggest trade-off: It is a cable, not a product. No ear cups, no headband, no microphone boom. If your headphones are broken or you do not own a compatible pair, this cable does nothing for you.
• Arama Cordless Phone Headset — biggest strength: A complete, purpose-built telephone headset with a noise-cancelling boom mic, external volume control, mute button, on-ear cushions and a lightweight stainless-steel headband, made for Panasonic, AT&T, Vtech, Uniden, Gigaset, RCA and Grandstream handsets with a round 2.5mm port.
• Arama Cordless Phone Headset — biggest trade-off: It is locked to phone duty. The 2.5mm jack and the 20 Hz–7 kHz frequency range are tuned for speech on a cordless handset, not for music, gaming or plugging into a laptop.
• Who each pick is for: Mr Rex → you already own compatible Bose/JBL/AKG headphones and want a wired, mic-equipped cable for calls, gaming controllers and phones with a 3.5mm port. Arama → you spend hours on a cordless landline phone and want a comfortable, hands-free headset with real call controls.
The Mr Rex 2.5mm is best understood as a repair-and-upgrade part. The 2.5mm plug is the end that goes into your headphones, and it is built for a specific family of them: Bose 700, QuietComfort QC45, QC35II, QC35 and QC25, plus JBL E45BT, E55BT, E65BTNC, Everest and Tune series, plus AKG models like the Y50BT, Y500 and Y600NC. The other end is a 3.5mm jack with a 135-degree angle, which matters more than it sounds. That bend takes the stress off the connector when the cable snags on a desk edge or gets yanked in a backpack, and it is a genuine durability point for daily heavy use. If you have ever killed a straight headphone cable by bending it at the plug, you know why this design exists.
Buy it if you own compatible Bose, JBL or AKG headphones and want one cable that handles music and hands-free calls on a phone, controller or laptop. Skip it if your headphones are not on the compatibility list, or if you are shopping for a headset rather than a cord.
Arama Cordless Phone Headset: Who It's For
Arama's headset is the opposite kind of product: everything is included, and everything is pointed at one job. The 2.5mm jack is sized for cordless and landline handsets, and the compatibility list is broad within that world — Panasonic DECT 6.0 phones with a round 2.5mm port (KX-TGxx series), most AT&T, Vtech, Gigaset, RCA, Uniden and Grandstream handsets. It is wired, with no wireless technology at all, which is exactly what you want for a phone that already lives on a base station.
Comfort is clearly the design priority. A lightweight stainless-steel headband, skin-friendly materials, enlarged soft ear cushions and a soft temple pad are all aimed at the same problem: people who wear a headset for an entire shift. The on-ear cups with over-ear cushion shaping and an ergonomic contour are meant to reduce pressure and squeezing rather than clamp down. Controls are deliberately simple — volume up and down, answer and end, and a mute button for the microphone, all reachable one-handed. The external volume control can boost audio to higher levels when a caller is quiet. The dynamic driver covers 20 Hz to 7 kHz, which is the classic telephone band: speech comes through clearly, and you should not expect it to double as a music headset.
Arama also backs it with a two-year warranty and 24-hour email support, which is a real consideration for something used daily in a home office or call center. Buy it if you take calls on a cordless landline handset and want a comfortable, hands-free headset with a mute button. Skip it if your priority is music, gaming or PC audio — that is not what this is built for.
Side-by-Side: Which Should You Choose?
• Best for reviving headphones you already own → Mr Rex 2.5mm. It is a direct replacement for the detachable cable on Bose 700, QC45, QC35II, QC35, QC25 and many JBL/AKG models.
• Best for long-call comfort → Arama Cordless Phone Headset. Stainless-steel headband, enlarged cushions and a soft temple pad are designed around extended wear.
• Best for call controls → Arama Cordless Phone Headset. Dedicated volume buttons, answer/end and a microphone mute, all on the cord.
• Best for music, gaming controllers and laptops → Mr Rex 2.5mm. The 3.5mm end feeds PS4/Xbox controllers, computers, laptops, phones and Hi-Fi gear — the Arama's phone-tuned 20 Hz–7 kHz range is not meant for that.
• Best for cable durability → Mr Rex 2.5mm. The 135-degree angled 3.5mm jack, zinc alloy control box and braided tangle-free cord are all stress- and wear-oriented details.
• Best for a single, complete purchase → Arama Cordless Phone Headset. No headphones required, no adapters to think about, plus a two-year warranty.
• Best for travel and storage → Mr Rex 2.5mm. A 5-foot cable with a Velcro strap disappears into a headphone case or backpack pocket; a full headset does not.
In my opinion, the honest answer is that these are not competitors — they are answers to two different questions. If your Bose or JBL headphones still sound great but the cable died, or you want an inline mic for calls on your phone or controller, I would buy the Mr Rex 2.5mm. It is cheap insurance for hardware you already like, and the angled jack and zinc alloy control box are the right details for daily abuse. If your problem is a cordless phone and hours of talking, I would buy the Arama Cordless Phone Headset instead — the boom mic, mute button and comfort-focused build are things a cable simply cannot give you. Pick based on what is sitting on your desk right now, and check the current price on Amazon before you commit.
what is an inline mic on headphones
An inline mic is a small microphone built into the cable itself, usually inside a little control box, rather than on a boom arm in front of your mouth. The Mr Rex 2.5mm is exactly this: a microphone and volume control sit on the cord between the 2.5mm headphone plug and the 3.5mm source jack. It is fine for calls and voice chat, but it will not isolate your voice the way a dedicated boom mic does.
how to use wired headphones with mic on pc
Plug the headphone end into your headphones and the 3.5mm end into your PC's audio jack — or into a controller or phone if that is your source. Your computer should then show the Mr Rex cable as both an output and an input device, and you select it in your call or chat app. One caution: many laptops have separate headphone and mic ports, so if your PC does not have a combined 3.5mm socket, you may need a splitter.
It is designed for cordless and landline handsets with a round 2.5mm port, and Arama lists Panasonic DECT 6.0 KX-TGxx series plus most AT&T, Vtech, Gigaset, RCA, Uniden and Grandstream handsets as compatible. The safest move is to check your exact handset model against the compatibility list before ordering. If your phone has a standard 3.5mm jack instead, this headset is not the right fit.
Yes. The 3.5mm end feeds phones, tablets, laptops, computers, PS4 and Xbox controllers, MP3 players and Hi-Fi systems, and the 24K gold-plated jack and OFC wire are there for clean audio transfer. Just confirm your headphones are on the compatibility list first — Bose 700, QC45, QC35II, QC35, QC25, JBL E45BT/E55BT/E65BTNC and several AKG models fit, while Sennheiser and Audio-Technica do not.
