• EARLA TEC's biggest strength: a 3.5mm-to-2.5mm cable around 1.5 m long that fits Bose QC25/QC35, SoundLink and SoundTrue headphones, plus a straight-and-L-shaped plug pair that suits awkward jacks.
• EARLA TEC's biggest trade-off: the spec sheet covers Bose and phone compatibility broadly, but it lists no gold plating, no cable-length flexibility beyond the fixed 1.5 m, and no stated interference shielding.
• Callez's biggest strength: a 155 cm cable (about 5.09 ft) with 24K gold-plated connectors and oxygen-free copper wiring that resists EMI/RFI, plus voice-assistant activation on the remote.
• Callez's biggest trade-off: compatibility is narrower and pickier — it's built for specific 2.5mm-jack headphones like Bose 700/QC25/QC35/QC35II/QC45, JBL Tune and AKG models, and it explicitly does not work with Beats or Sony.
• Who each pick is for: EARLA TEC for QC25/QC35 and older Bose users who want a simple, long replacement cord; Callez for Bose 700/QC45 and JBL Tune owners who want a more premium-feeling cable with a longer warranty.
The EARLA TEC cable is the straightforward option. It's a replacement cord and extension wire for Bose QuietComfort QC25 and QC35, and it also plays nice with SoundLink and SoundTrue headphones. On the device end, the 3.5mm plug is listed as compatible with iPhone 3GS through 6 Plus, Samsung phones and other Android models, plus PCs.
What stands out to me is the plug design. You get two male plugs — one straight and one L-shaped — on a cable that runs about 1.5 m (150 cm). That L-shaped end matters more than it sounds. If your headphone jack sits on the side of the earcup or in a tight spot, a right-angle plug takes the strain off the connection and stops the cord from kinking every time you move. The outer material is TPU, which the sheet describes as soft and durable.
Who should buy it: QC25 or QC35 owners who lost or frayed the original cable, and anyone who wants a longer cord for desk work or watching TV across the room. Who should skip it: if you own a newer Bose 700 or QC45, or JBL Tune and AKG headsets, this cable's compatibility list doesn't call those out — check your jack size carefully before buying.
Callez Replacement Audio Cable: Who It's For
Callez takes a more engineered approach, and you can feel that in the spec sheet. The cable is 155 cm — essentially the same reach as the EARLA TEC — but it's built from TPE with a 24K gold-plated straight plug and oxygen-free copper (OFC) conductors. The gold plating is there for conductivity and corrosion resistance, and the OFC wiring is designed to resist electromagnetic and radio-frequency interference. In plain terms: the design is aimed at keeping the signal clean.
On the 2.5mm side, Callez targets a specific list: Bose 700 (NC700), QuietComfort QC25, QC35, QC35II and QC45, JBL Tune 710BT, 660NC and 760NC, and AKG Y40 and N700NC, plus other 2.5mm-jack headsets named in its description. The 3.5mm end reaches iPhone, Samsung, most smartphones, computers, laptops, Mac, iPad, iPod, tablets and console controllers with a single 3.5mm jack. Two caveats are spelled out: newer iPhones need Apple's original Lightning-to-3.5mm adapter, and Xbox needs its own headset adapter.
The remote goes a step further than EARLA TEC's. It handles volume up/down, play/pause, track skipping, answer/end calls — and it can activate voice applications. The built-in mic works with phones and computers. Callez also lists a 45-day free replacement and a 2-year warranty, and the extra features include short-circuit protection and a tangle-free design.
Who should buy it: Bose 700, QC45 or JBL Tune owners who want a modern, well-specified replacement with a longer warranty. Who should skip it: Beats and Sony headphone owners — Callez states plainly that this cable is not for those — and anyone with a headset not on its compatibility list, since it's a pickier fit.
Side-by-Side: Which Should You Choose?
• Best for Bose 700, QC45 or JBL Tune users → Callez. Its 2.5mm list covers those newer models; EARLA TEC's does not.
• Best for cable length → a tie. Both land around 1.5 m (150 cm vs 155 cm), so neither wins on reach.
• Best for clean signal design → Callez. Gold-plated connectors and OFC wiring aimed at reducing interference.
• Best for awkward jacks → EARLA TEC. The included L-shaped plug handles tight, side-mounted ports better than a straight-only plug.
• Best for warranty confidence → Callez. A stated 2-year warranty and 45-day replacement policy versus EARLA TEC's 1-year manufacturer warranty.
• Best for voice-assistant users → Callez. Its remote can activate voice applications; EARLA TEC's sheet lists calls, volume and track control.
• Best for simplicity and broad phone support → EARLA TEC. It lists a wide range of iPhone and Android models with no adapter caveats.
If I were buying for a specific modern headphone, I'd go with the Callez Replacement Audio Cable. In my opinion, the gold-plated connectors, oxygen-free copper wiring and the longer warranty make it the more reassuring pick for a Bose 700, QC45 or JBL Tune. But if I owned QC25 or QC35 headphones and wanted a no-fuss cord with an L-shaped plug for a tight jack, I'd take the EARLA TEC instead — it simply fits that job cleanly. Match the cable to the model you actually own, and either one does the job.
The EARLA TEC sheet lists QC25, QC35, SoundLink and SoundTrue — it doesn't name the Bose 700. If you own a 700, the Callez cable is the safer match, since its list includes the 700 (NC700).
No. Callez states clearly that its cable is not for Beats or Sony headphones and only fits the specific models named in its description. Check your model before ordering.
Both offer mic, volume and call handling. Callez adds track skipping and voice-assistant activation on top, so if you use a voice assistant, that's the one I'd lean toward.
