First, however, we turn to the smaller, completely wireless in-ears, the Panasonic RZ-S300W with touch sensor control and Amazon Alexa built-in, with IPX4 splash protection and other features. PROS: Very good sound quality Long battery life Great value for money CONS: No wireless charging of the case No ear recognition Construction and scope of delivery of the Panasonic RZ-S300W The two TWS models from the manufacturer, the Panasonic RZ-S300W and the RZ-S500W tested here are almost identical in terms of their external appearance, apart from the differences in the details in the silver contrast ring surrounding the driver covers. However, a not entirely “unimportant” difference should be emphasized here: While the charging boxes of both models look completely identical from the outside, the earpieces of the Panasonic RZ-S300W are significantly more compact than those of its “big brother.” With housing dimensions of just 1.5 x 1.5 x 2.1 centimeters and a weight of no more than four grams per listener, the ultra-compact test candidate is already in the realm of the tiny 1MORE ColorBuds (about 1.7 x 1.4 x 2.4 centimeters and 4.1 grams). Nevertheless, dynamic drivers with a 6-millimeter neodymium magnet can be found in the tiny housing, as well as powerful batteries with which the small earbuds can reliably last for many hours on the go – not bad. The scope of delivery is also not bad: in addition to the headphones themselves and the charging case equipped with the USB-C standard and status LEDs, there are also silicone ear tips in four different sizes. Bluetooth, battery, and functionality The Panasonic RZ-S300W comes with Bluetooth version 5.0 and supports the audio codecs AAC and SBC and the wireless profiles A2DP, AVRCP, HSP, and HFP. As with the Cambridge Audio Melomania 1, the Blaupunkt BTW 10, the 1MORE ColorBuds, or the TWS sports headphones JBL REFLECT FLOW, the connection to mobile players is established through automatic switching on and pairing when the receiver is removed from the charging case. Both the earphones and the charging case are equipped with powerful lithium-polymer batteries, thanks to which the test subject can operate wirelessly for up to 7.5 hours on one charge and up to 30 hours in total by charging in the charging case. The charging case is fully charged after two and a half hours, the earphones themselves after two hours. And with the Quick Charge function, the Panasonic RZ-S300W is ready for another 90 minutes of wireless music playback after only 15 minutes of charging. In addition, the highly compact test candidate has an intuitive touch sensor control, a practical “Ambient Sound Mode,” and, thanks to built-in microphones, a headset function on board. And in case it rains outside again – hello autumn …! -, the test person is also equipped with IPX4 splash protection. Furthermore, the TWS model tested here is compatible with the voice assistants Google Assistant and Siri from Apple – and can also come up with “Alexa built-in”; it has the ubiquitous voice assistant from Amazon almost directly on board. Last but not least, the Panasonic RZ-S300W can also be controlled and configured using the free “Panasonic Audio Connect” app. The true wireless handset in practice Like its larger sister model, the RZ-S500W, the Panasonic RZ-S300W not only has a tastefully designed exterior but also has an equally pleasant feel. With a slight twist, the receiver was perfectly placed in the ear in no time – and remained there in the practical test with a secure hold even during longer listening sessions. At the same time, thanks to its compact format and feather-light weight, the mini earphone was barely noticeable for many hours – very pleasant, the whole thing. On top of that, the small size benefits from another plus point, which sets it apart from the larger RZ-S500W: the look when carried. Does the larger model look a bit like a “Frankenstein-like” button in the ear – similar to the other true wireless models such as the Technics EAH-AZ70W, the Sennheiser MOMENTUM True Wireless or the BOSE SoundSport Wireless sports headphones, “disappears” the test candidate, on the other hand, literally in the ear. In practice, pairing took place very quickly, and as a matter of course, it was also completely automatic with devices connected once. Moreover, the Bluetooth connection had no dropouts but was always stable – as was the crystal-clear telephone connection when the test person was used as an in-ear headset. And the wireless range, which the manufacturer specifies as “up to ten meters,” was also able to be fully exploited by the small earphones without any problems, as demonstrated in a practical test. And the true wireless headphones tested here also knew how to confirm all the manufacturer’s information on the subject of battery performance almost precisely in practice. And finally, there was absolutely nothing to complain about with all the functions with which the Panasonic handset comes around the corner: From the intuitive touch sensor control to the “Ambient Sound Mode,” which is practical in everyday mobile use, to the control he mini earphones via an app and the use of various voice assistants – including Alexa built-in – not only worked naturally and without problems with the RZ-S500W but also with the Panasonic RZ-S300W tested here. This is what Panasonic’s first TWS model sounds like But not only the big brother, but the RZ-S500W also has a lot to offer in terms of sound. No, the extremely compact TWS headphones Panasonic RZ-S300W tested here also worked after the usual 72-hour burn-in phase on both the smartphone and various digital audio players such as the FiiO M5, the FiiO M11, the Pioneer XDP-300R and to offer a lot in terms of sound technology to our reference DAP iBasso DX220 : The Panasonic RZ-S300W showed itself at its best in the listening test, giving a finely resolved, authentic, and overall round sound. Sure, the “big brother” RZ-S500W that we recently tested sounds a little more coherent and rounder overall. Nevertheless, the test candidate doesn’t need to hide from comparable competitors from its price range, such as the Blaupunkt BTW10, the Cambridge Audio Melomania 1, the 1MORE ColorBuds, the Lypertek TEVI, the HUAWEI Freuds 3i, or the HONOR Magic Earbuds. The Panasonic RZ-S300W equipped a wide variety of music tracks from various genres with an astonishingly rich bass foundation – which is all the more remarkable, not least because of the smaller driver and its more compact format compared to the RZ-S500W. In addition to the powerful punch in the lows that characterizes the listener tested here, the RZ-S500W also features a little more subtlety in the design of the bass contours. Nonetheless, soundedElectro tracks by Jon Hopkins and Trentemøller are similarly crisp. The same applies to the reproduction of the electric bass in rock, pop, and funk titles such as OK Go’s “A Million Ways,” Dua Lipa’s “Don’t Start Now,” or “Tieduprightnow” from the Parcels. And the representation of the double bass in jazz pieces is not to be despised either. The Panasonic RZ-S300W also reproduced the highs clearly and in detail; it did not reveal any problems in the representation of high voices and at the instrument level, for example, also with saxophone solos such as in Foreigner’s rock classic “Urgent.” Fortunately, the slight emphasis on high and low pitches is by no means at the expense of the reproduction of the middle-frequency range: Although this was slightly cautious compared to the very high and very low tones, it was nonetheless handy and with a feeling for details – even with demanding source material such as the tracks “Tatatango” or Tchavolo Swing “by the Minor Swing Quintet. Here the small TWS receiver from Panasonic was able to prove its abilities in terms of impulse fidelity. The test subject did just as well in the hearing test – especially because of its construction, technology, and compact size – also in terms of dynamic behavior. For example, the Panasonic RZ-S300W mastered larger dynamic jumps in classical orchestral works with ease. His audio stage presentation was just as convincing in this musical segment as with live material or in the song “Homeless” by Paul Simon and Ladysmith Black Mambazo – although Panasonic’s larger RZ-S500W true wireless headphones did even better in this discipline. Ultimately, it can be said that with the Panasonic RZ-S300W, thanks to its technical sound quality, almost every music genre can be heard pleasantly well – thanks to its great fit in the ear, even for hours and despite the lack of noise-canceling, it is surprisingly pleasant and relaxed even in ambient noise. Conclusion With the Panasonic RZ-S300W, the Japanese technology giant has launched a successful and comparatively inexpensive TWS debut. Just like the sister model RZ-S500W, the handset tested here has a stylish design and is extremely comfortable to wear over the long term. It is also equipped with cool features such as a powerful battery, IPX4 protection, and Alexa built-in. The advantage of the test person’s smaller size and weight than the “big brother” RZ-S500WThe ANC function falls victim, and the driver is also a bit smaller here. Nevertheless, the test candidate also delivers a remarkably round sound and good passive noise suppression, thanks to its good fit. If you can get over the mentioned “negative” points, you are right with the Panasonic RZ-S300W.
