Reasons Why You Should Buy Them

  • Panasonic RZ S300W are the small and cheaper "younger brother" of the RZ-S500W headphones with the same matte, textured finish and available in three color options - Deep Black, Dusty White and Mint Green
  • They have a splash-resistant IPX4 rating to manage sweat or adverse weather conditions, which makes them good for outdoor workouts without any worry
  • 6 mm dynamic driver units deliver balanced, pleasant sound quality with solid bass, natural mid-range, slightly boosted, clear treble to keep the energy high during training
  • Integrated touch controls and MEMS microphone allow you to answer/end phone calls, control music playback, adjust volume, skip tracks and connect to Google Assistant, Siri or Alexa
  • These Panasonic True wireless earbuds are small and fairly light, offering a comfortable and secure fit while running or gym workouts without worrying about falling out of your ears
  • Bluetooth 5.0 provides a stable connection (in our test up to 35 meters) even in crowded environments and helps reduce battery consumption
  • They offer brilliant sound isolation as tips of three different sizes help create the perfect seal that blocks most external sounds
  • With the "Panasonic Audio Connect" app you can make some fine adjustments via smartphone, such as EQ adjustments, Bluetooth pairing, skipping tracks, volume adjustment, prioritizing sound quality or connectivity, auto shut on/off, searching for your missing earphones, firmware update and selection of phone’s virtual assistant
  • You will get up to 7.5 hours of battery life on a single charge, another 22.5 hours with the charging case, and there is also a quick charge function that provides an additional 1.5 hours of running time with just 15 minutes of charging
  • Each bud receives its own Bluetooth signal and works independently, so each bud can be used alone in solo mode to listen to music or answer phone calls
  • With the auto-shutdown feature in the app, you can set the headphones to automatically shut down after a few minutes of inactivity to extend battery life

Reasons Why You Should Avoid Them

  • No support for advanced Bluetooth codec such as aptX, aptX HD or aptX LL for better sound quality, these headphones only support AAC and SBC codecs
  • The lack of support for higher quality codecs also causes significant latency while enjoying HD video or game content and are not the best option if you want to use them to watch Netflix or Apple TV
  • When it comes to higher frequency sounds, sometimes they sound a little harsh due to a slight overemphasis on the treble which hurts the overall audio reproduction
  • The plastic charging case is of poor quality, feels brittle, the lid seems to break easily. It is also twice the size of the Apple Airpod's case, and is not easy to put in your jeans pocket
  • The case is not compatible with wireless charging, it means that it cannot be recharged simply by placing on the back of the new high-end Android smartphone such as Samsung S20 Series or on the Qi compatible wireless charging pad
  • Although Panasonic True Wireless Earbuds RZ S300W have Bluetooth 5.0, there is no multi-device connectivity, which means that only one device can be connected at a time
  • The MEMS microphone is good enough to capture vocals for voice commands, the same cannot be said for call quality. People on the other end of the call struggle to hear the voice in a moderately noisy environment
  • They don't have a noise canceling function to filter out low-frequency external sounds, if you want to use your headphones while commuting, we recommend to opt for a higher-end RZ-S500W, which are one of the best noise-canceling earphones on the market
  • There is no ambient/transparency mode that lets some external sounds in, this function is very useful to keep you aware of the surrounding environment while running or cycling on a busy city street

Highlights

  • The ultra-compact, stylish, comfortable, truly wireless headphones for music, podcasts, calls, smartphone content and more
  • Touch sensor antenna ensures a strong, independent left-right connection for smooth, uninterrupted playback in the most crowded places
  • Premium 6mm driver units deliver dynamic bass and treble tones for clear and powerful sound
  • Elegant, high-quality earbuds designed to easily adapt to the natural contours of the ear canal for a snug, perfect fit
  • High performance MEMS microphone and Labyrinth structure minimize noise for clear call quality in windy places
  • Touch controls for music playback, volume and tracks, answer calls and connection to the voice assistant
  • Up to 30 hours (buds and charging case) of uninterrupted playback on a single charge
  • With an IPX4 splash-proof rating, it can be used safely anywhere and, in any weather
  • Panasonic Audio Connect app to control music playback, adjust volume levels, connect to voice assistant and more
  • Three color options are available for the Panasonic RZ S300W: Black, White and Green
