help Sony MDR-XB50BS FAQ
Are the Sony MDR-XB50BS wired or wireless?
The MDR-XB50BS are wireless Bluetooth in-ear headphones, not a wired 3.5 mm earbud model. Sony rates battery use at up to 8.5 hours and lists about 2.5 hours for charging.
Are the Sony MDR-XB50BS waterproof for swimming?
They have an IPX4 water-resistance rating, which covers splashes and sweat from ordinary workouts. IPX4 does not mean the earbuds can be submerged or used for swimming.
What kind of sound do the MDR-XB50BS produce?
Sony lists a 0.47-inch dome-type dynamic driver and a 4 Hz to 24,000 Hz frequency response. The XB branding refers to Extra Bass, so the tuning emphasizes low frequencies rather than aiming for a flat studio sound.
Do the MDR-XB50BS stay in place during exercise?
The package includes arc supporters in sizes S, M, and L plus multiple silicone ear tips. That design is meant to improve stability while running, but the correct tip and supporter size still depend on the user's ear.
