Hi there,
Thank you so much for your feedback on the 7HZ Timeless headphones.
We are glad to hear that you appreciate the convenience of the 7Hz Timeless. We understand that its performance in terms of ambient noise isolation may not have met your expectations. The poor isolation may be related to the choice of ear tips. The size and shape of the ear tips should fit the customer's ear canal for better isolation. Additionally, the way the headphones are worn can also affect the isolation. If the headphones are not secured properly, it may cause sound leakage and affect the clarity of the audio.
To assist you further, we will reach out to you via email to gather more information about your situation.
Thank you for your understanding and patience.
