We appreciate your time in providing feedback on our JBL Reflect Aero TWS. We understand that the noise cancellation of this product didn't meet your expectations. This product comes with different sizes of ear tips and ear fin enhancers that you can choose from to fit comfortably into your ear. You may try the "Check My Best Fit" test in the JBL Headphones App, which will help you get the best sound quality depending on the size of the ear tip and fins.

Thanks for your feedback. To achieve the best seal and secure fit, you may try the three sizes of ear tips and powerfins enhancers that come with our JBL Reflect Aero TWS to know which best fits your ear. Next, create a tight seal within your ear canal. To do this, angle the ear tip slightly downward to make it easier to insert into your ear then gently twist the earbud to fit it securely into the shape of your ear. Alternatively, you can try other ear tips from third-party retailers that will fit your ear. If you need further assistance, please contact our customer support.
