Wired Headphones Vs. Bluetooth – Where are we now?

Is Bluetooth Good, or Do You Need Wired Headphones for Better Sound?

“Aren’t wireless headphones worse than wired ones?”

This is one of the most common questions I get when people find out I work in the headphone industry. It’s a valid concern—almost everyone uses headphones nowadays.. But with technology moving fast, not everyone keeps up with the latest advancements, leading to outdated biases that can result in buying the wrong or unnecessarily inconvenient headphones. Here is a little history on wireless headphone tech, which can help explain why some people might still be living in the past with headphones.

The Early Days of Bluetooth Audio

When the first Bluetooth headphones hit the market, they were designed primarily for hands-free phone calls. In the early 2000s, mobile phones had become ubiquitous, and a significant portion of the population was talking on their phones while driving. This led to an increase in driving-related incidents, prompting many states to ban handheld phone use while driving. The solution? Bluetooth earpieces.

These early earpieces weren’t designed for high-quality audio—they didn’t need to be. Bluetooth had a very limited bandwidth back then, but for phone calls, you only needed a frequency range of about 100Hz to 8kHz to understand speech, even though human hearing extends from 20Hz to 20kHz.

Many people still remember those early Bluetooth devices and may not realize how much the technology has improved. Today, Bluetooth has evolved into a global wireless standard with vastly improved bandwidth and new codecs that support high-quality, low-latency, and even lossless audio.

Bluetooth Audio for Entertainment

Between its use for phone calls and where we are now, Bluetooth also became important for travel. As smartphones gained the ability to play movies and games, wireless audio became a convenient way to enjoy content on the go. However, early Bluetooth had noticeable latency issues—meaning that, in movies, dialogue wouldn’t sync with lip movements.

Thankfully, this problem has been mostly solved. I’ve taken plenty of flights using wireless earbuds and headphones, and syncing issues are rarely a problem anymore. That said, if you’re shopping for new Bluetooth headphones, always check that they support the latest Bluetooth version to ensure the lowest latency. As of now, Bluetooth 6 is the newest standard.

Audio Quality: Bluetooth vs. Wired

One of the biggest concerns people have about Bluetooth is sound quality. In the past, Bluetooth compression limited audio fidelity, but manufacturers have since introduced new codecs that allow for high-quality, even lossless, audio streaming.

For example:

  • Sony’s LDAC and Qualcomm’s aptX Lossless allow for higher-resolution audio over Bluetooth. 
  • Modern smartphones support these codecs natively, but you may need to enable them in your Bluetooth settings. 

For most listeners, the difference between a high-quality Bluetooth connection and a wired connection is negligible. However, if you’re an audiophile or working in professional audio, there are still reasons to keep a wired option around.

The Case for Wired Headphones

While Bluetooth has improved significantly, wired headphones still have their advantages.

  1. No Wireless Interference – Bluetooth can experience dropouts in crowded areas, like busy train stations, where too many devices are competing for bandwidth. With a wired connection, you don’t have to worry about signal congestion. 
  2. Guaranteed Lossless Audio – While Bluetooth codecs have improved, a wired connection ensures you’re getting true lossless audio without compression artifacts. 
  3. Higher Sample Rates – Some wired setups support sample rates up to 192kHz, which can deliver incredibly detailed sound if you have high-resolution music files. This is known as Pulse Code Modulation (PCM). 

The Verdict: Is Bluetooth Good Enough?

Cutting the cord

Worth it to cut the cable and go wireless?

Yes—Bluetooth audio has come a long way and is now a great option for most people. If you buy a well-designed pair of Bluetooth headphones with the right codecs and features, you can enjoy high-quality, low-latency, and convenient wireless audio.

That said, wired headphones still have their place. If you work in audio production, want an uninterrupted connection in crowded environments, or just prefer the reliability of a wired connection, they’re still a great choice.

At the end of the day, the best headphones are the ones that fit your lifestyle. Do a little research, read reviews, and don’t assume that more expensive means better quality. Happy listening!
