Afterglow Wireless Headset Buzzing Noise

This headset was purchased to replace an entry level Logitech set from about 10-12 years ago. I wanted a comfortable headset for video conferencing that supported usb-c, since both my Pixelbook Go and MacBook Air only have usb-c ports. The fact that this headset can also easily convert into a standard stereo jack was also very appealing. I'm not ready for a wireless headset since I dislike charging too many devices and the mics on Bluetooth wireless headsets usually rate poorly (nearly always, the complaint is that they are underpowered and too quiet). I've used this headset now for numerous many hour long calls. It is lightweight and comfortable, my ears do not get hot, and it does an amazingly good job at blocking out background noise without any active noise canceling technology. The ear pad material was softer than I was expecting and it appears to sink around my ears for a close fit. Sound quality has been very good, and when I asked the people on the other side of my calls how I sounded, they all confirmed that I was clear and easily understood. The cord is very long, and the usb-c connector makes a tight fit. Setup was the same as any other usb headset.

For years I had been using the older Sennheiser RS 120 wireless headset which operated in the 926-928 MHz frequency range. The performance was adequate, but the unit suffered from multipath cancellation (signal reduction due to the out of phase combination of multiple reflections). You will notice this when you move your head slightly, and there would be a sudden, and audible, change in signal amplitude or a short burst of background noise. As I had need for an addition system, I decided on the RS 175 as it seemed to have good reviews. I have not been disappointed. The RS 175 operates in the 2.4 GHz band with digital modulation. While 2.4 GHz systems are also subject to multipath propagation deterioration, I noticed none with this system, even with the headset taken outside onto the patio with the transmitter 40+ feet away. As typical with digital modulation systems, there was a threshold effect -- if the headset got out of range, the signal would abruptly disappear, quieting the audio -- in the past, you would simply be greeted with noise. In addition, I very much like the Bass Boost and Surround Sound options which can be quickly selected at the press of a button on the headset. The one negative for the headset is that you need to really take the headset off in order to figure out which button to press. I find this a rather minor inconvenience as I am not changing audio level, bass boost or surround sound options on the fly. In summary, Sennheiser did a superb job with this unit. The audio quality is excellent (I used an analog input -- an optical interface also exists for even better quality) and the annoying multipath effects so common with many wireless headsets are non-existent.

[This review was collected as part of a promotion.] INZONE H7 headset is absolutely the best wireless that I ever used. The noise cancellation is fantastic. The headset is lightweight and comfy. I would definitely recommend

I have been using the PST8 power station for about two weeks now to replace my $10 cheap power strip. I mainly bought it to attempt to resolve an audible buzzing noise in my headphones when connected to a desktop headphone DAC/amp. After plugging the DAC/amp directly into the PST8, the buzzing noise went away entirely. This was with both the digital filter outlet as well as one w/o filtering. Either way, I'm pretty confident the PST8 is delivering much cleaner power and that it resolved my specific issue. Happy with the purchase, although note this is much bulker than it appears in photos.

Yep, this solved the buzzing noise I was getting sometimes when the fridge was running. It seems very well built, and the positioning of the outlets is well-thought out so that I can arrange just about any combo I have tried without covering up outlets, thereby rendering them useless. No complaints. The cord is good quality and long enough to be useful in places where outlets are sparse.

It blocks out the noise so you can hear all the different audio in the headset.

No rattle or buzzing!

Occasional buzzing feel but other than that amazing!

amazing product, you won't find a better wireless headset.

Paired it up with my Plantronics wireless headset and everything works great
