Very good, especially for those with impaired vision.
The buttons and labels are large clear. It's great for Seniors and is easy to use. The built-in microphone is fixed and omnidirectional. It plays through any standard stereo (3-conductor) 3.5mm earphones or headset, though &#34;in-ear&#34; earphones are best. Avoid &#34;Open Air&#34; headphones since the sound coming out of them will cause feedback. Also, very high sensitivity (greater than 100db) earphones work best since the amplification is not tremendous. The user's own voice gets amplified, so you have to get used to that. They're much better than &#34;cheapies&#34;. It does have a &#34;tone control&#34; that can boost either high or low frequencies. But I find the limited total frequency range of the device limits the usefulness of this feature. It has another jack on the front that allows you to directly connect the stereo RCA jacks on the back of a TV to this device with the included long cable. Plugging it in turns off the microphone, though you can toggle it back on so that both are on if you want. Overall it's a very good device.
