Samsung Galaxy Buds4 Pro (SM-R640) White

Galaxy Buds4 Pro

• “The Galaxy Buds4 Pro are extremely recommendable. I absolutely love the sound quality in them. The fit and the comfort are incredible. The microphones are really, really impressive. And they have pretty much every feature I would want. These are not only a jack of all trades, but also a master of quite a few as well.” Mike O’Brien
• “Your music will sound fuller with more delicate and precise high tones and an impactful (but not overwhelming) bassline rounding out your scores.” TechRadar, 02/2026
• “The Galaxy Buds4 Pro deliver a warm sound that’s tuned for the mainstream: bass is ample, without being overpowering, vocals are clean, and the high-end gives a great impression of detail. Tool’s Parabola hits hard on the chorus, but I was still able to pick out individual instruments.” Stuff
