Rapasopis brand does not need any introduction – it has long been well known to everyone who is at least somewhat interested in audio and video equipment. The company also produces wireless stereo headsets, and one of them, the RP-BTD5, was tested by us.
Appearance, design, ergonomics
The case of the headphones does not contain metal – both the cups and the headband are made of a combination of matte and glossy plastic, and the ends of the cups are made of rubber or a rubber – like soft material. This fact, combined with a fairly simple, utilitarian design, gives the impression of an inexpensive thing, some more affordable headsets look more solid and solid. But thanks to this choice of material, the headset is not heavy, and the headband is not too tight, and the pressure on the ears is minimal. Ear pads of the On-Ear type (semi-open) very poorly isolate the ears from external sounds.
The headband does not fold, but for ease of wearing around the neck and compactness when carrying the ear cups are made rotatable, and for a more precise fit, the ear pads, along with their plastic base, deviate slightly from the vertical position.
All buttons, as well as the charging Jack, microphone and led indicator are located on the right earpiece, and the electronics and battery are hidden inside it. Control of calls and music is placed on a large flat end of the earphone, the buttons are decorated in the form of raised symbols that indicate the corresponding functions.
The telephone functions are implemented only basic call answer and end, call rejection and more, that sometimes it’s necessary to transfer the sound between the headset and the phone. The headset remembers up to 8 paired devices. when connecting to the ninth device, the first one is deleted.
Simultaneous operation with two phones (Multipoint) is not implemented, and advanced phone functions such as call hold and conference call are also not supported. But all this is not necessary here – this headset is primarily for music. For its transmission, by the way, the most common SBC codec is used, which guarantees compatibility with any audio source and is able to provide quite high-quality playback.
Impressions from use
Given the well-known brand and yet not the lowest price, I expected a more or less decent sound. This was hinted at by the characteristics (18-20 000 Hz, 40 mm speakers), but, alas, I was very disappointed. In these headphones, the music sounds muffled, clamped. The first analogy that comes to mind is as if you were listening to the sound from a speaker through its back wall. The sound is unnatural, “plastic”.
Bass and treble are played quite cleanly and accurately, but exactly as long as no vocals or some mid-range instrument is connected – acoustic guitar, piano, cello, electric guitar (rhythm or solo), saxophone, etc. Such instruments are played noticeably louder, and against their background, both the bass and the “cymbals” of the drums sound as if very far away. Quite often there are extraneous sounds caused by the resonance that occurs in the case of headphones. The sound of medium frequencies in General is unpleasant, the vocals are lifeless, without nuances and details. You can hear the loss of sound quality during transmission even in loseless-format tracks, and mp3 files that are already compressed with losses are distorted even more. Perhaps a wired connection would save the sound, but this is not possible.
The autonomy claimed is impressive – up to 40 hours of playback. It looks very much like the truth – one full charge was enough for me for more than two weeks of testing. But there is a nuance here. This “longevity” is achieved, among other things, with the help of very Intrusive energy saving. If nothing is transmitted to the headset for 5 minutes, it gives a short beep and immediately turns off.
I would not have bought a Panasonic RP-BTD5 myself, and if I had been able to listen to them when I bought them, I would probably have chosen a different model. With all due respect to the brand, it was better to save on anything, but not on the sound quality — that is, on the main characteristic of headphones.
