MT339 vs MT398 Spec Breakdown
Track Length
The MassaMAX MT398 features a 55-inch SL track, which extends from the neck to the thighs. This specific length ensures broad coverage for the back and upper legs. The MassaMAX MT339 also uses an SL track, described as extending from the neck to the thighs with a 50% increase in massage area. While both models target the same general body regions with their long tracks, the MT398 provides a precise measurement of 55 inches. You should consider the MT398 if you want a clearly defined, extended track length for comprehensive back coverage.
Heat Therapy
Heating zones differ significantly between these two chairs. The MassaMAX MT398 includes dual-zone soothing heat therapy with carbon fiber heating in both the backrest and calf rests. This setup helps loosen tight knots and improve circulation in two major areas. In contrast, the MassaMAX MT339 offers lower back graphene heating therapy. This single-zone heat targets occasional and chronic strains in the lumbar region only. If you want warmth for both your back and your lower legs, the MT398 provides a more comprehensive heating solution.
Physical Dimensions
Size and footprint are important for your home setup. The MassaMAX MT339 measures 60.6 inches in length, 29.9 inches in width, and 44.5 inches in height, weighing 192 pounds. The MassaMAX MT398 is larger, measuring 64.6 inches in length, 29.9 inches in width, and 47.2 inches in height, with a weight of 208 pounds. Both are classified as X-Large. The MT398 requires more floor space due to its greater length and height. You need to ensure your room can accommodate the larger footprint of the MT398.
Control Features
How you interact with the chair varies by model. The MassaMAX MT398 includes AI voice control, allowing hands-free operation by simply speaking your demands to the chair. It also features a built-in child lock function to prevent accidental touches on the touchscreen. The MassaMAX MT339 highlights OTA Cloud Tech, which provides over-the-air updates for its 27+ massage programs. While the MT339 focuses on software evolution, the MT398 offers immediate hardware-level convenience through voice commands and safety locks. Choose the MT398 for hands-free convenience.
Massage Airbags
Both chairs utilize airbag systems for compression massage. The MassaMAX MT339 specifies 32 airbag points with three levels of pressure for the shoulders, arms, feet, and buttocks. It also includes foot rollers for kneading. The MassaMAX MT398 lists airbags targeting the shoulders, arms, hips, calves, and feet. It emphasizes a full-body airbag massage system. While the MT339 provides a specific count of 32 points, the MT398 explicitly includes the hips and calves in its airbag coverage. Both offer extensive compression, but the MT398 highlights broader limb coverage.
Choose the Right Massage Chair
Users wanting AI voice control
The MassaMAX MT398 includes AI voice control, allowing hands-free operation. You can simply speak your demands to start specific programs. This feature is not listed for the MT339. The MT398 also offers dual-zone heating for the backrest and calves, providing broader warmth coverage compared to the MT339's lower back graphene heating. Both chairs feature 4D massage and zero-gravity positions.
Users seeking cloud program updates
The MassaMAX MT339 supports OTA cloud technology, giving you access to 27+ professional massage programs. New sequences are added regularly via over-the-air updates. This keeps your experience fresh. The MT398 does not mention this cloud connectivity feature. Both models use 4D massage mechanisms and SL tracks, but the MT339 offers this evolving software library as a distinct advantage.
Users needing child safety locks
The MassaMAX MT398 includes a built-in child lock function. You can press and hold a button for three seconds to lock the touchscreen controller. This prevents accidental operation by children or unintended touches. The MT339 data does not list this safety feature. Both chairs offer full-body airbag massage and zero-gravity reclining, but the MT398 adds this specific control security.
Users preferring foot rollers
The MassaMAX MT339 features foot rollers for full-roller kneading on the feet. This stimulates acupoints directly. The MT398 lists airbags for the feet but does not mention mechanical rollers. Both chairs provide enveloping airbag pressure for the legs. If you prefer mechanical kneading over air compression for your feet, the MT339 offers this specific mechanical feature alongside its 4D massage and SL track coverage.
