Relatively inexpensive fully wireless TWS headphones from Panasonic, mainly notable for their average battery life and the ability to adjust the volume directly from the headphones. But in general, we have a rather classic, as for this price range, model in the in-ear form factor and with minimal additional functionality. The special shape of the headphone stem improves their fixation in the user's ear.
For sound reproduction in Panasonic RZ-B100W headphones, dynamic drivers with dimensions of 13 mm are responsible - a very good indicator for this type of equipment. Connection to a smartphone, laptop or other signal source is carried out via the Bluetooth v 5.0 wireless protocol, which provides a reliable connection within a radius of up to 10 m. The headphones themselves are capable of “playing” up to 4 hours, and the complete case provides them with the ability to quickly recharge for more 16 hours of work. To charge the case, the USB-C interface is used. Protection against dust and moisture according to the IPX4 standard is provided - the headphones are not afraid of sweat or light rain, but they absolutely cannot swim. The case itself is made of white matte plastic, has a compact size and fits comfortably even in your pocket.

Model overview based on user reviews
The Panasonic RZ-B100W headphones offer good sound quality and support for SBC and AAC audio codecs, making them a decent choice for everyday use. They feature a stylish design with a long stem, which some users find advantageous for call clarity. However, the headphones have notable drawbacks, including connectivity issues where the earbuds do not always synchronize, and the left earbud sometimes fails to charge properly. Users have also reported discomfort over time due to the specific ear placement design. While the build quality is generally appreciated, some users have experienced glitches and durability issues. Despite these concerns, the headphones are considered to offer good value for money and can compete with more expensive models in terms of sound purity. However, potential buyers might want to consider alternatives if they prioritize reliability and comfort.

Overall, the headphones are okay, but nothing special, and you can find more interesting options now. These are not top for their price. Additionally, they don't always synchronize with each other, and only the left earbud plays, so you have to reconnect. However, one feature is that these earbuds have a long stem, which might be an advantage for some. Unfortunately, it doesn't have any power over others... Always flicker Do not always connect with each other  Galina: use Panasonic RZ-B100W more than year |
I recently got these headphones, but I already have something to say about them. The length of the stems surprised me; they are too long, longer than my other headphones. One might have thought that this was due to impressive autonomy with a large battery. But no, it's decent but ordinary. My ears got tired before they ran out of battery. The stems are so long and wide that they even managed to fit Panasonic labels on them. There are quite a few, and there's one on the case too. On one hand, the headphones are designed so that they can only be placed in the ear in one specific way (finally). There is a special groove they attach to. On the other hand, over time, this becomes tiring, and you feel like adjusting the headphones or taking them out to rest. This design might be ideal for someone. Perhaps the voice will be heard better by the interlocutor during calls with such a stem, but I haven't checked yet. Overall, the sound is not unpleasant, it's normal. There is touch control, but it's somewhat strange: one earbud controls volume, and the other controls forward/backward. The case is convenient, making it easy to take out the headphones. When connected to a smartphone, a female voice in the headphones announces it, but with a desynchronization, how come! However, afterward, they work normally, and this effect is no longer present. Sometimes I need specifically earbuds They take one single correct position in the ear I believe they won't suit girls Perhaps too many Panasonic inscriptions Over time, they cause me discomfort But the main downside is they constantly blink once connected, at a moderate frequency, but I don't understand why this was even done. Relatively long charging time.  See Sea: use Panasonic RZ-B100W less than month |
I don’t recommend it, it’s a waste of money Sound Build quality, glitches, the left earphone stopped charging and then fell apart. |
