What is a B-stock product?

A product becomes B-stock when it can no longer be sold as new. It can simply be a product that has been returned by a customer or it may have packaging that is damaged or missing. It’s possible that the product itself may show slight signs of use or damage too. All B-stock products are fully checked to ensure that they work properly and you can find details of why the product is a B-stock in the information above.

B-stock information

The B-stock tab on the product page shows information about the B-stock product. Be aware that this information supersedes anything you may read in the product description. The product description includes text and specifications about the product in its brand-new state. It’s possible that a B-stock item may be missing accessories mentioned in the text or specifications, for instance, but if so, this will always be mentioned in the B-stock information. B-stock products also include photos of the actual B-stock item so that you can see exactly what it looks like.

Sennheiser XSW IEM SET - E (823.2 - 831.8 MHz) Complete Monitoring System

I bought two of these Sennheiser XSW IEM SETS- E systems for my Daughter as her main Christmas present for 2025, as she was looking to take music to the next level next on stage with her rock band. Using IEM's helps the band to here themselves a lot better on stage rather than having to rely on floor monitors. Although my Daughter is not the best with tech like this on stage. She found this Sennheiser system easy to setup, operate and navigate while in rehearsals. Highly recommend this system for its ease of use, the build quality, and most importantly good stable sound through to her in ear buds.
