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

Panasonic RZ S500W are one of the best noise-canceling headphones for commuters under $200. The louder your environment, the greater the ANC strength, as the dual Hybrid Noise Canceling (feed-forward mic and a feed-back mic) and 50 indoor/outdoor noise cancellation levels filter most external sounds to fully enjoy your music

RZ S500W headphones have a simple, circular design with a matte, textured plastic finish, a shiny chrome ring wrapped around the small ear cap and available in two professional-looking color options - Deep Black and Dusty White

Lightweight build and four different sizes of silicone tips help keep the buds comfortable and firmly in your ears, whether you're in the gym, on the bus or in the office without worrying about falling out of your ears

When it comes to audio performance, the dynamic 8mm driver units offer strong bass, natural mids and solid, rich highs that are perfect for modern genres such as hip-hop, jazz, mettle and pop. If necessary, this can be adjusted using the equalizer in the Panasonic app as desired

With built-in touch controls and MEMS microphone, you can answer/end calls, control music playback, adjust volume, skip tracks, select ANC/Ambient Noise mode, and connect to Alexa, Google Assistant or Siri

They deliver one of the best runtimes of up to 6.5 hours on a single charge with ANC ON, another 19.5 hours with the charging case and a quick charging function that offers an additional runtime of 70 minutes with just 15 minutes of charging

With the "Panasonic Audio Connect" app, you can make some fine adjustments via your smartphone, such as EQ adjustments, Noise-canceling and Ambient Noise adjustment, Bluetooth pairing, skip tracks, volume control, prioritization of sound quality or connectivity, auto-power on/off, search for your missing headphones, firmware update, and choice of phone's virtual assistant

Bluetooth 5.0 provides a stable connection (in our test up to 35 meters when used outside the home), even in crowded environments, and helps to reduce battery consumption

The earbuds support mono-listening or answering phone calls with the left or right bud, as each bud receives its own Bluetooth signal and operates independently

The "Ambient Noise" mode is a small but practical function if you need to keep your ear open for external announcements without taking off your headphones

With IPX4 splash resistance, they can handle sweat and rain better than other truly wireless earbuds and can be used safely anywhere and, in any weather

The auto shutdown function in the app allows you to set the headphones to shut down automatically 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

For some users, noise cancellation is too strong. At best, these headphones are hard to use for long listening sessions. Fortunately, you have the option to adjust the intensity via the app

Panasonic RZ-S500W headphones are equipped with Bluetooth 5.0, but there is no multi-device connection. In other words, you can only connect to one device at a time

The plastic charging case is of poor quality, brittle and the lid seems to break easily. It's also twice the size of the Apple Airpods case and can't be easily put in your jeans pocket

Earphones have moderate IPX4 ratings. They can cope with some sweat and rain, but they are not designed for severe water pressure or submerged, so be careful if you want to rinse them off

Advanced Bluetooth codecs such as aptX, aptX HD and aptX LL are not supported for better sound quality. These headphones only support AAC and SBC codecs

High-quality audio codecs are not supported, so there is a significant delay in enjoying HD video and game content, and they are not the best option if you're using them to watch Netflix or Apple TV

The Panasonic RZ S500WE buds are a pair of larger headphones and protrude a little from the ears compared to other truly wireless models

The MEMS microphone is good enough to capture the vocals for voice commands. The same is not true for call quality. It seems distant and blurry, the person you call struggles to hear your voice in a moderately noisy environment

Built-in touch sensors are extra sensitive and it's quite easy for you to accidentally play/pause music or skip tracks when you put the earbuds on or adjust them in your ear

The case doesn't support wireless charging, which means it can't be recharged just by placing it on the back of a new high-end Android smartphone, such as the Samsung S20 Series, or on a Qi-compatible wireless charging pad

Unless noise cancellation is necessary, the Panasonic RZ-S300W earphones are a great alternative and they are also much cheaper. They lack noise-canceling functionality and have slightly smaller drivers (6 mm), but otherwise all the features are the same
