Vandoren and Gleichweit represent two very different approaches to clarinet mouthpiece making. One is a large French manufacturer with a century of history and global distribution. The other is a small Viennese workshop producing a limited range of precision mouthpieces by hand and CNC machine. Both are serious professional instruments. The question is which one is right for you.
This is a genuine comparison — not a sales pitch. Both brands have real strengths, and the right answer depends on your playing style, your priorities, and what you actually need from a mouthpiece.
About Vandoren
Vandoren was founded in Paris in 1905 and is probably the most recognised name in clarinet accessories worldwide. Their mouthpieces — the B45, B40, M30, and others — are used by professional players in orchestras, conservatories, and studios on every continent. They make mouthpieces in hard rubber (ebonite) and offer a very wide range of models covering different tip openings, chamber shapes, and tonal characters.
Vandoren’s strengths are breadth of range, proven track record, and availability. You can find their mouthpieces in almost any serious music shop globally, and you can reliably expect consistency between units of the same model.
About Gleichweit
Gleichweit mouthpieces are made by Josef Gleichweit in Vienna — a city with one of the most distinctive clarinet traditions in the world. The mouthpieces are CNC-machined from high-grade synthetic material to very tight tolerances, with each unit inspected individually. The range is deliberately focused: a limited number of models, each carefully developed for a specific playing context.
Gleichweit’s strengths are precision, consistency, and tonal character. The Viennese sound — warm, centred, blending — is baked into the chamber geometry and facing design. The built-in O-ring system is a practical feature absent from most competitors: it ensures a secure, airtight fit without any cork or tape adjustment.
Sound Character
Vandoren
Vandoren mouthpieces vary considerably across the range. The B40 (used extensively in the French conservatory tradition) has a more open, brilliant quality — projecting and clear. The M30 is warmer and more centred. The B45 sits between the two and is the world’s best-selling clarinet mouthpiece for good reason: it suits a very wide range of players.
In general, Vandoren mouthpieces lean toward the French clarinet sound: a tone that’s clear, articulate, and projection-focused.
Gleichweit
Gleichweit mouthpieces are consistently warmer and more focused than their Vandoren equivalents at the same tip opening. The chamber design produces a blend of tonal core and warmth that sits well in ensemble contexts — a tone that contributes to the sound of a section rather than standing above it.
Players coming from the French tradition sometimes find Gleichweit darker than they expect. Players from the German or Viennese tradition, or those who prioritise blend over projection, typically adapt immediately.
Precision and Consistency
Vandoren
Vandoren has strong manufacturing quality control, and consistency between units of the same model is generally reliable. Hard rubber can vary slightly between production batches due to material properties, but this is rarely a significant practical issue at the professional level.
Gleichweit
CNC machining of synthetic material gives Gleichweit an edge in unit-to-unit consistency. The tolerances are tighter and the material doesn’t vary. If you order a BW 7-4, you get exactly a BW 7-4 — not one that plays a little differently because the rubber cured at a slightly different density. This consistency is a meaningful advantage for players who tour, use multiple instruments, or need to replace a mouthpiece quickly.
Range and Availability
Vandoren
Vandoren has one of the widest mouthpiece ranges available, covering Bb, A, bass, E-flat, and contrabass clarinet, with multiple models for each. They’re stocked by almost every serious music retailer globally and available for immediate purchase at most conservatory shops.
Gleichweit
Gleichweit’s range is more focused. They make mouthpieces for Bb, A, bass, E-flat, bassett horn, and contrabass clarinet, with models spanning closed to open tip openings. They’re sold primarily through myclarinetstuff.com, and include a trial option (the Test Box) that most retailers don’t offer.
Price
Vandoren mouthpieces range from around $100 for standard models to $300+ for premium editions. Gleichweit mouthpieces are similarly priced in the $130–$245 range. At this price point, both represent serious professional instruments — neither is a budget option, and neither should be.
Trial Options
This is where the comparison gets practically important. Most Vandoren purchases are final — you buy the mouthpiece, and if it doesn’t suit you, you either adapt or resell it.
Gleichweit offers the Test Box: try up to 5 mouthpieces at home for 7 days for $40. Play them on your own instrument, with your own reeds, in your own rehearsals — and keep only what works. The $40 fee is credited toward your purchase. For a $200+ buying decision, this significantly lowers the risk.
Which Is Better for Orchestral Playing?
Both brands have professional orchestral players using them. Vandoren’s M30 and M15 are common in symphony orchestras worldwide. Gleichweit’s closed and medium tip models are designed specifically for the focused, blending tone that orchestral ensemble work requires.
If you’re in a French or American orchestral tradition, Vandoren may be the more natural fit. If you’re in a German or Viennese tradition — or if you prioritise blend, warmth, and intonation consistency over projection — Gleichweit is worth serious consideration.
Which Is Better for Beginners and Students?
Vandoren’s student-range mouthpieces are widely available, well-made, and a solid choice for anyone starting out. Gleichweit’s models are also suitable for advanced students, with the Test Box making it easy to try before committing.
The Honest Conclusion
Neither brand is universally better. Vandoren offers breadth, global availability, and a proven track record across many playing styles. Gleichweit offers a more specific tonal character — Viennese warmth and precision — with higher manufacturing consistency and a lower-risk purchasing experience through the trial option.
If you’ve been playing Vandoren for years and are broadly happy, you may not need to change. But if you’ve been chasing a warmer, more centred tone and haven’t found it in the Vandoren range, Gleichweit is a logical next step.
The Test Box makes it easy to find out. Try up to 5 Gleichweit mouthpieces at home for 7 days and compare them directly against what you’re currently playing.
