The Logitech BT adapter has been in the house for a few weeks now and I really like it.
Have the Logitech Z623 2.1 speaker set here at home as a replacement for audio equipment. This set is connected to the BT adapter instead of a cable to the laptop. The laptop with Windows 8.1 has built-in Bluetooth, so let's look for the adapter from Logitech. Within seconds the laptop had found it, after which I manually connected it once, which is remembered every time the laptop is started. The speaker set plays an audio fragment when there is a connection and the adapter makes the blue light shine brighter during the connection. Then followed the first "test"... streaming music wirelessly to the adapter and hearing it over the speakers. It's as if a cable is just connected because it all plays flawlessly. What I did run into in the beginning was the equalizer settings of Windows. I am a real music lover and love good renderings. My laptop has DTS and with that you can improve the audio signal. The disadvantage is that you can forget about this technology if you play music wirelessly over Bluetooth. The BT adapter itself does not have software to tune sound (pnp), so you have to do that PER APPLICATION yourself. That means that you have to set EVERY media player (think Winamp/AIMP/VLC etc) yourself to get the perfect sound for you. that is a bit more cumbersome, because you are used to doing this in 1 mixing console under Windows. However, once set it is no longer a problem. There are absolutely no hitches or interference with other equipment and what my acquaintances were afraid of: infringement/eavesdropping on your music that is impossible. If another device wants to connect to your adapter, for example your smartphone (or that of your neighbors), Windows will give a message and a series of check numbers must be entered what Windows presents you and what "the coupler" does not. gets to see. So listening is not possible. However, which is possible, if the laptop is turned off and you have your speakers turned on, someone who is within range of your BT signal can connect to the BT adapter and play music. With me they have to be in front of my windows because the signal does not (or very limited) pass through walls. And what is the "fun" of having your smartphone play music that your neighbor can hear on his speakers? So I could follow the audio from my neighbors at that time instead of the other way around. In any case, here the speakers are turned off when my laptop is off. What a pleasure to be able to play music through your living room without a wire. I should have bought this a long time ago. What is unclear according to Coolblue, however, is whether I can also connect a BT mouse to the BT built-in adapter on my laptop if I have already connected it to my BT adapter from logitech (again saves such a USB nano receiver in your USB port) unless the mouse and my BT built-in adapter of my laptop support "unifying" (cooperation with 1 receiver, simply put) I have no idea if that is the case, so I think I'll try it out in the store :) Keep in mind is that if you adjust the connection to, for example, your smartphone, your laptop has lost the connection at that moment. Sometimes that gives some problems to restore the connection to your laptop (even if Windows just sees the adapter). Then it is a matter of switching off the power of the Logitech BT adapter, after which you can establish a connection again ( kind of memory connection in the adapter so to speak) The device itself is small and fits easily in the palm of your hand, looks super sleek and lights up blue. If there is no connection, the blue light dims slightly, but you cannot turn it off. So it remains in standby mode with blue lighting. So keep that in mind if you plan to buy this adapter. The sound of movies in HD quality also allows the adapter to stream perfectly throughout the room. Perfect item for me, very happy with it.
