Neumann just expanded its 3-way monitor line with the KH 310 II and the brand-new KH 350. Both are serious reference tools, but they are aimed at slightly different rooms and workflows. The question most engineers are asking is simple: which one actually makes more sense for a treated home or project studio in 2026?
Quick Decision
Choose the KH 310 II if: you want maximum precision, tighter bass control, and a compact nearfield that stays analytical
Choose the KH 350 if: you need more low-end authority, higher output, and a monitor that can handle larger listening distances or immersive work
Biggest truth: both require a properly treated room — neither will fix a bad acoustic environment

Neumann KH 310 II 
Best for: Critical nearfield mixing where precision, imaging, and controlled bass matter more than raw output
Typical price: $3,000–$3,400 each
See Neumann KH 310 II →Key Differences at a Glance
The KH 310 II is the refined evolution of the classic KH 310. It keeps the sealed-box design, improves amplifier power, lowers distortion, and adds modern DSP with MA 1 alignment support. It is still primarily a precision nearfield.
The KH 350 is a new model with a larger cabinet, bass-reflex design, deeper low-frequency extension (down to roughly 27–30 Hz), and more output capability. It sits between true nearfield and midfield use and is better suited for rooms that need more physical scale and low-end authority.
If you are still on smaller Neumanns, the Best Budget Studio Monitors and earlier high-end compact posts show the step-up path most people take before reaching this level.
Neumann KH 350 
Best for: Studios that need stronger low-end, higher SPL, and a monitor that can work at slightly longer listening distances or in immersive setups
Typical price: $3,600–$4,000 each
See Neumann KH 350 →What Each Monitor Actually Delivers
The KH 310 II keeps the tight, time-accurate bass that sealed designs are known for. Imaging is extremely precise and the midrange stays neutral and revealing. It is the more analytical of the two.
The KH 350 gives you more extension and a greater sense of scale. Bass has more physical weight, and the larger waveguide helps maintain consistent directivity. It is still a Neumann reference monitor, but it feels more authoritative in bigger rooms or when low-frequency content is critical.
Genelec 8341A 
Best for: Engineers comparing Neumann’s new 3-ways against a proven point-source flagship alternative
Typical price: $4,500–$5,000 each
See Genelec 8341A →Side-by-Side Reality Check
- Bass character — KH 310 II is tighter and more controlled; KH 350 has more extension and physicality
- Maximum output — KH 350 has the advantage in larger rooms
- Imaging & precision — both excellent; KH 310 II edges it for pure critical detail
- Room size flexibility — KH 310 II prefers true nearfield; KH 350 handles slightly longer distances better
- Immersive / multi-channel — KH 350 is the more natural fit for LCR and surround roles
Pros and Cons
Neumann KH 310 II Pros
- Extremely precise and analytical
- Sealed design gives tight, time-accurate bass
- Excellent imaging and consistency
- DSP + MA 1 support for room alignment
- More compact footprint
Neumann KH 310 II Cons
- Less low-end authority than the KH 350
- Still expensive for most home studios
- Requires solid treatment to justify the cost
Neumann KH 350 Pros
- Deeper bass extension and more output
- Better suited to larger listening distances
- Strong candidate for immersive and film work
- Still maintains Neumann’s reference character
Neumann KH 350 Cons
- Larger and more expensive
- Bass-reflex design trades a bit of sealed-box tightness
- Overkill for small untreated rooms
Neumann KH 120 II 
Best for: The more accessible high-end Neumann option if the 310 II / 350 level is still too far for your current room or budget
Typical price: $1,500–$1,800 per pair
See Neumann KH 120 II →Clear Recommendation Tiers
Most treated home / project studios:
The KH 310 II is the more sensible choice. It delivers the classic Neumann precision in a size that still works for nearfield work.
When the KH 350 makes more sense:
You have a larger treated room, need stronger low-end for modern music or film, or are building toward immersive monitoring.
If budget or room size is still limited:
Stay with the KH 120 II or equivalent compact high-end monitors and invest the difference in better treatment and calibration first.
