Detail 01
Narrow 3.85mm rim
Concentrates pressure on a small band of lip. That's what buys the flexibility, and it's also what tires you out faster.

What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Concentrates pressure on a small band of lip. That's what buys the flexibility, and it's also what tires you out faster.
Detail 02
Smallest cup in this range. Less lip vibrating means more high-register security and less raw volume than the 18mm 4.
Detail 03
Matches the standard 7. Sets how much resistance you feel; smaller throats push back more, which many players use for control.
Detail 04
Shared across every size here, so switching between them changes the rim and cup feel, not the back end of the taper.
Detail 05
Cosmetic difference from the plain versions. The rim contour and dimensions are the same as the standard 7N.
Detail 06
Identical 17mm cup and 4.50mm throat. The N drops the rim from 4.50mm to 3.85mm — that is the whole difference.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Narrow rim. The 7N has a 3.85mm rim against the standard 7's 4.50mm, with the same 17mm cup and 4.50mm throat.
The 5 is the size described as a good beginner choice. The 7N's narrow rim rewards a developed embouchure and can wear out a new player.
The 4N, with an 18mm cup and 4.70mm throat, is the narrow-rim option described for range and volume. The 7N is the smallest of the group.
It helps flexibility, and the 7N's smaller 17mm cup is the bigger factor for high playing. Expect less endurance in trade.
