The Bose QuietComfort Ultra Earbuds 2nd Gen can handle workouts, though they're not designed as dedicated sports earbuds.
Water Resistance
IPX4 rating protects against sweat and light rain. Adequate for gym use but avoid submersion or heavy rain.
Fit System
Nine combinations of ear tips (S/M/L) and stability bands (1/2/3) provide secure fit for most users. Note: the earbuds are chunky and may not suit smaller ears.
Running Considerations
Some users report subtle "thunking" sounds from footsteps, especially when sweating affects the seal.
Safety Features
The Bottom Line
Excellent for casual workouts where audio quality is the priority. Serious runners or heavy gym users may prefer sports-focused alternatives with higher water resistance.
