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
On the smaller side for horn. Easier to center high notes; less room to open up for a big low register.
Detail 02
Narrow. More lip contact with the air stream means quicker flexibility, but less cushion over a long rehearsal.
Detail 03
Standard for horn. Keeps enough resistance to shape notes cleanly without choking off volume.
Detail 04
Straighter taper that firms up the core of the sound and keeps intonation stable across registers.
Detail 05
Slight grip on the lips, which helps placement stay put. Some players react to silver and need gold instead.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Same 17mm cup diameter and 4.50mm throat. The 7N has a narrower rim (3.85mm vs 4.50mm), which trades cushion for flexibility and easier high-register work.
It's less forgiving. There's less surface to rest on, so placement matters more and endurance takes longer to build. The payoff is faster slurs and better upper-register response.
The 5 is the better starting point — a standard rim with a shaped funnel cup is more forgiving while you're learning placement. The 7N suits players who already have a set embouchure.
Check whether your horn takes an American or European shank taper — the two aren't interchangeable, and a mismatch will sit too loose or too deep in the leadpipe.
