Power Switch On Logitech Headphones Affects Speakers

I use this to switch between my ipod dock and my xbox using my logitech z-2300 speakers and it works flawlessly, there is no sound quality loss nor interference.

I must state that I am not an audiophile and purchased these headphones to listen with my iMac and Logitech Z623 speakers. I have varied kinds of music on my computer; Broadway shows, opera, Sinatra, Bennet, symphonies, etc. The sound on these headphones blows me away. They are rich, deep and I do not need the volume to be turned up very much. I highly recommend them.

Really like the ease of setup for this Logitech keyboard/mouse combination. The keyboard does not have a power switch. The mouse does have an on/off switch. The only thing that bothers me is when using with a laptop, the keyboard is wider than the actual laptop.

Needed a simple, well-built switch to switch between headphones and monitor speakers. Could also be used in the future to take two inputs from different sources and play through the same output. Compact and easy to velcro to the side of a desk, out of the way.

Helps me get the affects i was looking for

THERE IS NO POWER SWITCH. I can not use them where I intended to because I have to move furniture every time I want to turn them on or off. I bought a set over 15 years ago and they do have a power switch but they no longer work. So, now I’ve had to buy a different set of lower quality speakers to replace them because I’m unable to move furniture every time I want to turn them on or off in the location I wanted to use them because of my physical disabilities. A design flaw that resulted in me spending more money than I can really afford. The speakers and sound are excellent that’s why I bought a second set but, I would not recommend them to anyone because of the lack of a power switch.

I use this device for off-on switch for PC's, amps, speakers, lights, just about anything that requires power. This is my fourth unit.

Shortly after I purchased the Eco Max hurricane Ian's affects came through and we were without power for a few days and the Max helped greatly with keeping our freezers and refrigerators plus smaller appliances running. Easy to use and great product.

I use this amp to power headphones connected to an airplay device. I use the optical connection for ultimate quality. At fist I was concerned if it could adequately drive my 300 ohm Sennheizer HD600 headphones because it is just USB powered. But when I got it, It became clear that I had nothing to worry about! Wonderful, Clean, accurate sound. Excellent for both Classical music and hot Jazz. It can also serve as a preamp, so you could connect powered speakers, or a power amp and full size speakers. Although it works well usb powered from my Mac Mini, I advise getting the AC adapter so you are not draining usb power from other usb devices. Well packaged, come with a carry pouch, good fit and Finnish, responsive customer support. Simply Excellent at any price, fantastic at this price!

Before I bought this amplifier, I would have to connect my headphones (Sennheiser HD201 and eH350) to my desktop speaker's headphone output each time I wanted to use them (late at night, for example). In order to get roughly the same listening volume through my headphones, I'd have to really crank up the volume knob on my speakers (they take a lot of power compared to your typical earbuds). With the HA400, I can keep my headphones and speakers connected all the time. When I want to use my headphones, I just turn down the volume control for the port my speakers are connected to and turn up the volume for my headphones (and vice versa to use the speakers again). This amplifier really lets me enjoy my headphones. The amplifier seems really well built and solid. The input/outputs are all 1/4 stereo connectors (could be a con for some, but I have a bunch of 1/4-1/8 adapters already, so it's not a problem for me). The only thing that I feel it's really lacking is a power switch, but in reality, that's not a big deal to me. All in all, I highly recommend.
