How to Convert Sennheiser HD650 to Balanced

If you’re an audiophile looking to take your Sennheiser HD650 headphones to the next level of audio quality, converting them to a balanced connection might be the solution you’ve been seeking. Balanced headphones offer improved signal quality, reduced noise interference, and a more immersive listening experience. In this article, we’ll guide you through the process of converting your Sennheiser HD650 headphones to a balanced connection.

What is a Balanced Connection?

Before we delve into the conversion process, let’s briefly discuss what a balanced connection is. A balanced connection uses three conductors: two for carrying the audio signal (positive and negative) and one for the ground. This setup helps cancel out common-mode noise, resulting in cleaner audio with less interference.

Tools and Components You’ll Need:

1. Sennheiser HD650 headphones
2. Balanced headphone cable with the appropriate connectors
3. Soldering iron and solder
4. Heat shrink tubing
5. Wire stripper and cutter
6. Screwdriver (if needed)

Step-by-Step Guide to Converting Your HD650 to Balanced:

1. Prepare Your Workspace: Start by setting up a clean and well-lit workspace. Make sure you have all the necessary tools and components within reach.
2. Remove the Stock Cable: Carefully remove the stock cable from your Sennheiser HD650 headphones. You may need to unscrew or unclip the cable connector, depending on your headphone model.
3. Examine the New Cable: Take a close look at the balanced headphone cable you’ve chosen. Ensure that it has the correct connectors for your headphones and audio source. If the cable is longer than desired, you can cut it to the desired length.
4. Strip the Cable Ends: Strip the outer insulation of the new cable to expose the inner conductors. You should have three wires: two for the audio signals (positive and negative) and one for the ground. Use a wire stripper for this purpose.
5. Prepare the HD650 Connectors: If your new cable has different connectors from the stock cable, you may need to adapt them to fit your HD650 headphones. This may involve soldering or using an adapter. Follow the instructions provided with your new cable.
6. Solder the New Cable: Carefully solder the new cable’s conductors to the corresponding terminals on your HD650 headphones. Typically, the left channel is positive, the right channel is negative, and the ground is common to both channels. Refer to the wiring diagram provided with your new cable for guidance.
7. Secure the Connections: After soldering, use heat shrink tubing to cover and secure the soldered connections. This helps prevent short circuits and provides strain relief for the cable.
8. Reassemble Your Headphones: If you had to disassemble any part of your headphones to access the connectors, reassemble them following the manufacturer’s instructions.
9. Test Your Balanced HD650: Plug your newly converted balanced HD650 headphones into a compatible balanced headphone amplifier or source. Test them to ensure that both channels are working correctly, and the sound quality meets your expectations.

Conclusion

Converting your Sennheiser HD650 headphones to a balanced connection can significantly enhance your audio experience, providing improved signal quality and reduced interference. While the process may seem daunting at first, following this step-by-step guide can help you achieve outstanding results. Remember to take your time, work carefully, and ensure that you have the necessary tools and components before starting the conversion. Once completed, you’ll be able to enjoy your music with even greater clarity and fidelity.
