Jabees' bone-conducting speakers sit flat under your pillow and emit audio for your ears only. We've covered Jabees previously, with its single-speaker unit that could play SD-card-loaded soundscapes or connect to your smartphone for fuss-free bedtime audio. But it's worth noting that your environment is going to play a part in how well these speakers perform. And because they're bone-conducting, ideally the thinner or looser your pillow is, the louder the audio is likely to be. The standard unit available in Sunrise Yellow or Mist Green is currently on sale for US$49.99 (normally $59.99).
