With the wireless over-ear HD305B, the Japanese electronics giant Panasonic has launched Bluetooth headphones that, according to the manufacturer, are convincing both in connection with a television set and when listening to music on the go. We took a closer look at the Panasonic RP-HD305B and tested it for its practicality and sound performance.

Panasonic’sPanasonic’s product range extends from TV sets to cameras and headphones. The wireless over-ear tested here has been optimized for home theater applications, gaming, and playing music – a real jack-of-all-trades.

Scope of delivery and construction of the Panasonic RP-HD305B

Visually, the Panasonic RP-HD305B impresses with its simple, elegant, completely black design, strongly based on that of the Panasonic RP-HD610N that we last tested. In addition, the test candidate is equipped with large auricles that can be swiveled and tilted towards the ear, through which it can be brought to flat transport size. Unfortunately, unlike those on the HD610N, the earpiece’s shell cannot be folded in as well.

Generously dimensioned, very soft ear cushions enclose the built-in 40-millimeter neodymium HD converter of the Panasonic RP-HD305B. The high-precision headband, which clicks in 16 steps, is generously encased in fabric encased in a thin synthetic leather cover. Both the upholstery and the height adjustment also make a robust impression. While there is a 3.5-millimeter jack connection on the left auricle, the right side has various buttons. The USB port for charging the headphones is also located here. Furthermore, an anti-vibration transducer frame reduces unwanted shocks.

The quality of the Panasonic RP-HD305B can be classified as extraordinarily good, especially considering its price range. The high-quality first impression is also reflected in the scope of delivery of the headphones: This includes a two-meter long 3.5-millimeter jack cable. And a 0.5 meter long USB charging cable is also included. Two minor shortcomings: The USB cable is a type B and not a C standard. And a transport bag for on the go would have been pretty handy too.

Bluetooth, battery, and functionality

The Panasonic RP-HD305B is equipped for wireless transmission with Bluetooth 5.0, the latest Bluetooth generation. In addition, the manufacturer has given its product the standard codecs AAC and SBC and the Qualcomm codecs aptX and aptX Low Latency. The latter also ensures almost lag-free playback in connection with television sets. But, of course, they also have to support this codec themselves. Thus, Panasonic has optimized the listener for wireless connection with the TV set or streaming moving image material. Moreover, the Bluetooth signal is designed for the industry-standard distance of around ten meters. And this range was also confirmed in our practice test.

Furthermore, the HD305B, like the HD610N, has a wireless runtime of up to 24 hours thanks to the built-in battery, which we were also able to prove in our practical test using the example of the SBC mode. The handset also provides a full charge within the five hours specified by the manufacturer. In addition, the Quick Charge function enables up to two hours of wireless music playback time with just 15 minutes at the socket – this also came out pretty well in the test. Last but not least, the voice control of the handset should be mentioned at this point, as well as the possibility of making phone calls with it thanks to the integrated microphone.

The Panasonic Bluetooth Over-Ear in practical use

The Panasonic RP-HD305B sat comfortably on the head of several different testers as part of our practice test. And longer use was possible without any problems. The buttons on the side also proved to be easy to reach. However, after a short period of getting used to it, we blindly hit the right button.

With the help of those buttons, we could easily skip through tracks, regulate the volume, start or pause songs and choose between the two EQ modes, “Bass Enhancer” and “Clear Voice,” or leave the headphones in their default settings. The first mode, as the name suggests, emphasizes the bass frequencies. The second is particularly interesting for those who want to watch films with headphones. In this setting, the frequency ranges of the voice are particularly emphasized. This worked very well in our practice test, especially in action-packed scenes.

In addition, the wireless connection of the Panasonic RP-HD305B to mobile playback devices via Bluetooth was always very fast in our test. However, compromises have to be made in terms of high-res sound since high-resolution audio files can only be played with the jack cable connected. In addition, ambient noise is suppressed relatively well due to the closed over-ear design of the listener. However, there is still room for improvement here, as the test subject does not have Active Noise Canceling in contrast to the HD610N.

This is what the HD305B sounds like

After a burn-in phase of around 72 hours that every headphone had to go through before our hearing test, the Panasonic RP-HD305B also got down to business: We took digital audio players such as our reference player, the iBasso DX220, and the Pioneer XDP-300R or the super-compact FiiO M5 to help and played the Panasonic headphones with music extensively. It turned out that all-important frequency ranges are reproduced very well.

The sound that the RP-HD305B presented to us in the listening test can overall be described as hidden, which is particularly noticeable in the bass range: Nowadays, many manufacturers are trying to achieve a high level of bass emphasis. We were able to determine this, for example, in the tests of the two JBL models, LIVE 650BTNC and REFLECT FLOW. But even if you select the “Bass Enhancer mode” on the Panasonic RP-HD305B tested here, the bass range does not come across as overemphasized. The “Clear Voice” EQ setting, as expected, provided a better definition of the vocal parts. However, we liked the basic attitude best, as it is the most neutral. But of course, that is and will remain a matter of taste in the end.

The middle frequency range was reproduced with a fine resolution. At the high frequencies, the headphones seemed inconspicuous, partly reflected in a slightly ”musty” sound. For example, on the Jay-Z song “99 Problems”, the hi-hats stayed pretty much in the background. The impulse reproduction of the listener is great, and the reverberation rooms were also reproduced excellently by the Panasonic RP-HD305B. In doing so, he also got a lot right when listening to classical music. By the way: If you use the headphones wired, this is noticeable in terms of sound with a plus in radiance, so you should always have the jack cable with you.


Very good usability, and unobtrusive sound, and a high level of comfort are the strengths of the Panasonic RP-HD305B Bluetooth headphones. In addition, the quality of the wireless over-ear is rock solid. And its versatile functionality is also impressive. However, a carrying case included in the scope of delivery would have been desirable. Nevertheless, there is not much to complain about in this price range in terms of sound and beyond. In any case, the price-performance ratio is right here.
