B015 – Front Stereo Signal Amplifier Booster Headphones Speaker Amplifier Headset Dual-Audio SourceProduct description:
You have a line level signal source (TV audio, MP3 player, Video game, mobile phone, tablet, computer, record player), but desire louder sound or bigger volume?
A powerful signal amplifier receiver or volume control, you may need a long line connecting TV audio and the receiver on the other side of the room to provide high gain through any line level signal source, allowing longer cable operation or requiring “buffer” to amplify the lower volume. You may use it between the line level signal source and power amplifier as a signal amplifier, 3.5mm + RCA port matches almost all product interfaces.
The product improves the sound amplification and reduces ground noise by controlling the signal, and it has large dynamic range without produce cracking. It controls output volume through a sensitive volume knob, the output of the headphone interface can drive 16Ω-600Ω headsets, and uses AC9V transformer for power supply to ensure full power.

Fantastic keyboard
I did a lot of research before choosing this keyboard, and man am I glad I got it! The split is great, very comfortable. The arch is minimal, but it does the job. I also really like this scissor-switch technology, no more backspacing to fix a key that didn't register the first time! The built-in wrist rest is also really nice. I type a lot for work, and at a rate of 55 WPM. The keyboard gives just the right amount of feedback, and the keys are not mushy at all.
It's also a very good looking keyboard, and is very responsive. I have heard some people mention (not just on this keyboard) that they have some lag/delay with their typing. I would bet the farm that they have plugged the receiver into a USB hub. If you're going to do that, then get yourself a USB extension cable, because the hub will cause interference with ANY wireless dongle you plug into it. Just a foot or so of distance from the hub will alleviate that. I found that out with my prior Logitech keyboard, after lots of searching around for what the cause could be.
The ONLY thing I would improve is fairly minor: It does not have dedicated keys for Page Up/Down, Home, or End. You need to hold down the function key and use the corresponding arrow key for those functions. Not even remotely a deal breaker, this keyboard is fantastic in every other aspect.

Great Keyboard & Excellent Customer Service
I’ve been using this keyboard for almost 3 years and it has worked great for me the entire time. Comfortable, reliable, and perfect for long hours of work.
The customer service was also great — very responsive, helpful, and professional throughout the process.
Very happy with the product overall and would definitely recommend it.

Soft keyboards ( updated)
The keys fell off very easily after only 2.5 months of use. It is a nice and smooth keyboard. I like it, but it didn't last even 3 months. I am trying to get it repaired by them since it was so recent that I got it- I will update this review later once I hear from the manufacturer.
This is an update to my original post. I am extremely impressed with the quality of customer service and how fast they addressed my concerns regarding the product and they honestly back up their product. Not only did they respond fast, but they also replace my keyboard. Not just fix it, replaced the whole thing and it is also backed by their manufacturer warranty. I’m so happy and love that I get to have my keyboard back to use for hopefully a lot longer this time. It truly is a comfort keyboard and I love how smooth the keys feel when typing for long periods of time. Thanks guys for the prompt response!
Today 3/27/2026 I received my brand new keyboard to replaced the one with the broken keys and I’m so happy to it back again and fully working thanks guys for the great customer service. Truly appreciate it.

Great keyboard at the right price
I bought this to replace my old Logi Ergo K860. I like the idea of curved keyboard. But the distance between my left and right hands on Ergo K860 was bothering me ever since I bought it 5 years ago. I would say I never got used to it. The Ergo started to act up one day with one key F not working properly. I tried to fix it and considered getting another one, then I saw this keyboard with a much better price. So I took the chance and went with this cheaper option. I like this one better than Ergo for the following reason:
1. The layout is more comfortable. Yes, it took me a while to get used to it like I would with any keyboard. I don't have to twist my wrists to reach any keys.
2. Keys are not too loud. It's not going to silent, but better than Ergo.
3. Battery life is great. I make a living by typing my keyboard. I only charged this keyboard once so far (4 months).
4. The price is great for what I got.
