Review on SENNHEISER RS 175 Wireless Headphone System with RF Connectivity by Seunghyun Nahm ᠌
Good product, not disappointed.
In general, this upset me, and I almost went to take them back, but decided to straighten their frequency response with a multiband equalizer, since the drivers allow. What I've done: 30Hz -9dB 60Hz -2.5dB 250Hz +3dB 500Hz +5dB 1kHz +4db 2kHz -7db 4kHz -1.5dB With such an edit, I brought the frequency response to the form to which I was accustomed, and, in principle, I was satisfied. Now interesting. I took care in advance to change the leather ear pads to velor ones, because. the leather ones can peel off. The RS 175 does not have velor by default (there is for the RS 185), so I looked at the velor for the RS 160/170/180 series (they seem to fit in shape, judging by the photo) and ordered a pair. But in the end, I got leather ones. Why this happened is another question. The ear pads differ in the circumference of the cup shape, but it was not difficult to put them on the plate that attaches them to the cups. I turn off the equalizer for them. And about a miracle! The frequency response of the headphones leveled off to the values to which I brought them with the help of the equalizer. Those. With these ear pads, the default headphones sounded great. How it happened that regular ear pads "embellish" the sound to such a terrible state is also not clear to me. Most likely, the material of the ear pads has different reflective properties, but I was lucky to get exactly those that brought the sound in order. All this is subjective, of course. In the photo, headphones with new ear pads. In the other photo, the regular ear pads are the first row.
- Build quality Sound (in comments)
- Ear pads (in comments) ALC (may suppress dynamics a bit) - Comment starts here to meet character limit - I've been using the AKG K242 HD (semi)open-back headphones for many years. And all my subsequent headphones (for the street) I was looking for, focusing on the sound of AKG. For the music I listen to, they fit perfectly, in my humble opinion. It was necessary to purchase wireless headphones on the radio channel. I didn't hit my original target (slight delay). when transmitted to the headphones, the signal is digitized and converted back to analog by the headphones, which gives a noticeable delay of 40-50 ms for playing the instrument. Anyway, I decided to leave them and use them for their intended purpose (they are still faster than bluetooth headphones). And what was my surprise when I listened to them. Of course, I understand how the open design differs from the closed one, but I didn’t like the sound that Sennheiser “drilled” from the word “completely” - a raised subbass, a failed bass, 2kHz crawled up somewhere, which makes the guitars unheard, because that they start whistling. And in addition, there is a bass boost function that raises the bass and lifts the subbass even higher. For whom they do this, I have no idea.
