Sony WH-CH720N.

The Sony WH-CH720N is a wireless over-ear headphone model from Sony’s lineup. These headphones are part of the “CH” series.

 Key Features of the Sony WH-CH720N include:

  • Active Noise Cancellation (ANC): This feature allows the headphones to actively cancel out background noise, providing a more immersive and focused listening experience.
  • Bluetooth Connectivity: The headphones can be connected to devices such as smartphones, tablets, or laptops wirelessly via Bluetooth, enabling you to listen to music or take calls without the need for cables.
  • Built-in Microphone: The headphones likely have an integrated microphone, enabling hands-free calling and voice commands when paired with a smartphone or other compatible device.
  • Long Battery Life: Sony headphones typically offer extended battery life, allowing for hours of continuous playback and talk time.
  • Comfortable Design: Sony usually prioritizes comfort in their headphone designs, making them suitable for extended wear.
  • Customizable Sound Settings: Sony often provides companion apps that allow users to customize the sound profile of their headphones according to their preferences.


Factors that Contribute to the Professional Label for the Headphones:

  • Sound Quality: Professional headphones should offer high-quality audio reproduction, with accurate and balanced sound. This is particularly important for tasks like audio editing, mixing, or critical listening where precise sound reproduction is essential.
  • Durability and Build Quality: Professional headphones are expected to be robust and durable to withstand frequent use in various environments. They should be made from quality materials that can handle daily wear and tear.
  • Comfort: Comfort is crucial, especially if the headphones are worn for extended periods during work or professional tasks. Padded earcups and headbands, as well as an ergonomic design, are essential for comfortable wear.
  • Noise Cancellation or Isolation: For professionals working in noisy environments or those needing focused concentration, active noise cancellation or excellent passive noise isolation is a valuable feature.
  • Connectivity Options: Versatile connectivity options are important for professional use. Bluetooth connectivity for wireless operation is beneficial, but professional headphones may also provide wired connectivity options, such as detachable cables, for reliable audio transmission.
  • Battery Life (if applicable): If the headphones have wireless capabilities, a long battery life is advantageous, especially for professionals who need extended usage without frequent charging.


Key Aspects to Keep in Mind:

  1. Comfort: Ensure that the headphones fit comfortably on your head and ears. Prolonged usage of uncomfortable headphones can lead to discomfort and even pain.
  2. Volume Levels: Be mindful of the volume levels. Listening to music or audio at excessively high volumes can damage your hearing over time. It’s recommended to keep the volume at a reasonable level.
  3. Noise Levels: If you are using the headphones in a noisy environment, consider using noisecanceling features or isolation to reduce the need for higher volume levels.
  4. Listening Environment: Be aware of your surroundings, especially if you are walking, cycling, or doing any activity that requires attention to your environment. Avoid using headphones in potentially dangerous situations where you need to hear important sounds, such as traffic or emergency alerts.
  5. Wireless Connectivity: If using Bluetooth connectivity, ensure that your headphones are fully charged, and the Bluetooth connection is stable. Bluetooth range is limited, so keep your audio source and headphones within a reasonable distance to avoid signal dropouts.
  6. Battery Life: Keep track of the battery life, especially if you are using wireless headphones. Charge them regularly to ensure they are ready for use when needed.
  7. Maintenance: Regularly clean and maintain your headphones to keep them in good working condition. Follow the manufacturer’s guidelines for cleaning and storage.
  8. Compatibility: Ensure that your headphones are compatible with the devices you intend to use them with, whether it’s a smartphone, computer, gaming console, or audio interface.


Complementing Accessories AND Peripherals:

  • Carrying Case or Pouch: A protective carrying case or pouch helps keep your headphones safe from scratches and damage while traveling or when not in use.
  • Audio Cables: If your headphones support wired connectivity, having extra audio cables can be useful, especially if the original cable gets damaged or lost.
  • Bluetooth Transmitter: If you have audio sources that do not have built-in Bluetooth, a Bluetooth transmitter can allow you to connect wirelessly to your headphones.
  • Bluetooth Dongle: For computers or laptops without integrated Bluetooth, a Bluetooth dongle can add wireless connectivity to your device.
  • Replacement Earpads: Over time, earpads can wear out. Having a set of replacement earpads ensures you can maintain the comfort and hygiene of your headphones.
  • Headphone Stand: A headphone stand keeps your headphones organized and provides a dedicated spot to place them when not in use.
  • Audio Splitter: If you want to share audio with a friend or watch a movie together, an audio splitter allows you to connect two sets of headphones to a single audio source.
  • Audio Interface: If you use the headphones for professional audio production, an external audio interface can improve audio quality and offer additional connectivity options.
  • Headphone Amplifier: If you want to boost the audio output or drive high-impedance headphones more effectively, a headphone amplifier can be a valuable addition.
