At CES 2020 wireless earbuds appeared at almost every audio booth of any size, from anywhere in the world. And many accessory makers prominently displayed their cases, chargers, and charms made for Apple’s AirPods.

As we poured over the literature from multiple manufacturers we met with at CES, several characteristics became clear design standards among earbud manufacturers. All earbuds on the market need to address the following characteristics to be considered relevant.

Earbud Design Criteria

Battery life

Smaller earbuds usually mean more efficient electronics, but also means a smaller battery. Earbuds offer a variety of continuous playback times from 2-hours to 24-hours. The sweet spot seems to be 5-6 hours.

Wireless charging

Limited battery life for a wearable means coming up with ways to charge earbuds quickly, and with the need to chase down an electrical outlet.

Connectivity distance

Implementing Bluetooth® 5.0 greatly increases connection distance between devices, from 4.2’s 200 feet to 800 feet. Distance and speed/quality are tied in Bluetooth, which means that those manufacturers who choose 800 feet may not be leaving the 2Mbps transfer speed, which can also be used to transmit higher-quality sound over the signal.

Noise cancelation

Many earbuds offer passive noise isolation, which means that they have a good seal around the ear and sound dampening components that attempt to keep sound out. Active noise cancelation requires hardware to pick up ambient noise, and software to filter it out of the incoming sound stream. More lower-priced headphones will follow the lead set by Apple and Bose on noise cancelation.

Water resistance

Does the earbud support an IPX rating, and if so, does it cover a splash, and downpour, a swim around a pool, a deep-sea dive or a walk across a desert? (See this Wikipedia article for an explanation of IP codes). Some will list an IPX rating, while others will choose phrases like “some water resistance.”

Size and weight

Some earbuds are starting to disappear into the ear. It isn’t clear that the smallest versions will prove best for sound, features or battery life. Regardless of features fulfillment, the size of earbuds will matter for comfort and overall experience.

Special features

Several manufacturers offer the following features in an attempt to differentiate their products from the onslaught of now relatively easy to manufacturer devices.

  • Earbud location
  • Heath rate monitoring
  • Personalized hearing profiles
  • Special controls

As Serious Insights continues to evaluate new earbuds, we will include an evaluation against all the listed characteristics for our readers—and continue to update the criteria as the market evolves.
