Bluetooth or USB for Music in the Car?

[GeorgeLee]

You can listen to music in the car using either Bluetooth or a USB drive. Since both Bluetooth and USB interfaces in vehicles have different ports and comprehensive functionalities, you can choose between them based on your device's battery level and connection method. Bluetooth can eliminate noise and echo: Equipped with advanced digital signal processors and voice devices, it is suitable for any harsh environment, eliminating background noise and echo to ensure high-quality call performance for both parties, with an effective range of 10 meters. Bluetooth can automatically recognize mobile phones: It can connect to your phone without the need for cables or phone holders. You can control your phone without touching it, even keeping both hands on the steering wheel, using voice commands to answer or make calls. Users can conduct calls through the car's audio system.

I often use Bluetooth in my SUV to connect to my phone and play music, mainly for convenience. It automatically connects to my phone when I start the car, syncs my playlist without any hassle, and allows me to take calls directly through the car's speakers. However, it occasionally stutters on the highway, and my phone tends to overheat with rapid battery drain. My kid always plays with my USB drive, so I now keep a 256GB one in the armrest, loaded with over 800 lossless music tracks. The sound quality is noticeably clearer than Bluetooth, especially when listening to symphonies—the bass drum hits are particularly powerful. For long-term car use, I recommend having both options: Bluetooth for city commutes and a USB drive for high-quality music on long trips. Oh, and don’t buy the cheapest USB drives—they’re prone to chip burnout in hot weather. Opt for metal-shell models with better heat dissipation for durability.

Last time I accompanied a friend to the auto parts market to upgrade the car audio, the technician made a valid point: if you truly want to pursue sound quality, you should use a USB drive. Bluetooth transmission compresses audio, and even with aptX-supported car stereos, the details can't match a direct USB connection playing WAV files. My older car model only supports Bluetooth 4.0, which is fine for pop songs, but when playing rock, the guitar solos noticeably sound muffled. The current compromise is to buy a Type-C dual-head USB drive, so I can transfer songs from my phone without constantly plugging and unplugging. Actually, the latest car stereos support wireless CarPlay, but for Android users, a USB drive is still more reliable since car stereo systems update slowly, and many phones' Bluetooth protocols can't keep up. Remember to format the USB drive monthly to avoid lagging or crashes.

Who still uses USB drives in cars these days? Just connect your phone via Bluetooth and start your NetEase Cloud daily recommendations. Last week during a road trip, I tried my friend's USB drive—the playlist was full of 80s classics. It's 2024 now, with new songs dropping every few days, and using a USB means constantly remembering to update it. But Bluetooth has a major flaw: music gets interrupted when gaming with friends, like PUBG going silent right after parachuting. I've found that installing music apps directly on the car's infotainment system is way better—stream online with caching, and music automatically lowers when navigation speaks. I do keep a USB drive for rentals though, to avoid connecting to unfamiliar cars' Bluetooth and risking contact leaks. Oh, and wireless charging mounts + Bluetooth are the ultimate combo—no more battery anxiety.
