2-Pin to 3.5 mm Conversion

@markoa7

As a seasoned electrical engineer, I am more than comfortable working on non-detachable cables, and I can certainly guarantee a professional finish for your conversion project. I understand the importance of durable, clean re-termination and take pride in my precise solder joints and meticulous strain relief work using heat-shrink or equivalent, ensuring long-lasting audio performance. My diverse skill set aligns perfectly with your project needs. My extensive experience in PCB design and development will prove invaluable as I remove the existing two-pin connector and replace it with a low-profile 3.5mm TRS plug. Additionally, my skills in firmware development contribute to my deep understanding of various communication protocols, providing a thorough guarantee to correctly map your headphones' left-right channels without any hum, crackle or channel imbalance. Lastly, I embrace comprehensive testing as a core part of my development process. Your headphones will be returned not only fully tested but also ready to deliver the high-quality sound you seek. My commitment to delivering cost-effective solutions within stipulated deadlines further cements me as the best fit for this project. Let's connect and discuss your turnaround time expectations as well as preferred logistics for shipping. Photos of similar past works can be shared upon request for you to gauge my work quality. Thanks again for considering me!

Hello, I understand you’re looking to convert a hard-wired dual-pin airline headphone cable to a standard 3.5 mm stereo TRS jack, with a clean, durable, professional finish. I have hands-on experience with audio cable re-termination, fine soldering work, and headphone repairs where signal integrity and strain relief are critical. I will carefully remove the existing two-pin connector, identify and map the left, right, and ground conductors correctly, and install a low-profile 3.5 mm TRS plug suitable for phones, laptops, and audio interfaces. The work will include solid solder joints, proper insulation, and heat-shrink strain relief to prevent future cable fatigue. No mic or control circuitry will be added—pure, clean stereo audio only. Once completed, the headphones will be fully tested for channel balance, noise, continuity, and real-world playback to ensure there is no hum, crackle, or imbalance. The goal is a neat, factory-quality re-termination that looks professional and is ready for everyday use as soon as you receive it back. Thanks Asif

Being an electrical engineer is not just a job for me, it's a passion that I have cultivated over the past 6 years. My work involves circuit designing, PCB designing and more importantly, solutions as per the client needs which guarantees that I can deliver an elegant and durable re-termination for your headphones. My experience in handling different electronic projects has made me proficient enough to ensure correct channel mapping and no hum, crackle or channel imbalance in the audio. During my career, I have dealt with a variety of non-detachable cable situations, so transforming your dual-prong airline plug into a single 3.5 mm stereo jack is right up my alley. Besides technical expertise, I'm also noted for my good coordination and time management skills which ensures quick turnaround times without compromising on quality – something that you also emphasize on in the project description. Lastly, if you're concerned about the logistics for shipping or want to track the progress in photographs throughout this process, I'm here to cater to all your needs. To sum up, choosing me for this project can lead us towards ensuring an efficient and hassle-free transformation to your headphones sans disappointment plus a close collaboration where you are involved at every step of the process.
