Much better than similar devices!

I have previously (probably Identical to blueLino 4G without "plus") tested a Marmitek BoomBoom90, but so had already rather short distances (3m, sight) problems with the radio connection. A quick look inside the unit explained the problem: It was built only a small 1x2mm, built in Bluetooth radio antenna, which lies in a plane with the rest of the electronics.

In contrast, the reviewed here blueLino 4G plus does have the same electronic circuit board, but also about a 1x5cm large antenna that is built into the lid of the device. This causes the blueLino 4G can hold plus a significantly more stable wireless connection to Bluetooth partners than is the case with the Marmitek device. So here is a clear "plus" point for the blueLino 4G plus.

Sure it seems somewhat confusing, with one device what music "receives" from a higher range (20m are probably only a theoretical maximum value) to speak, but must remember you that this "music receiver" as opposed to a radio receiver to receive both and must send to the "music channel" establish the Bluetooth connection.

Apart from that one should hope for optimal sound quality for "APTX" not too high stuck because APTX is apparently supported only on very few or only on newer devices. Here APTX has two Dell laptops, two HTC smartphones ('Desire Z "and" Sensation ") are not supported and a Samsung Galaxy Tab S2. Surely I could support APTX with a USB Bluetooth adapter with a chipset from "Cambridge Silicon Radio" (ie the licensor of APTX codecs) retrofit, but if you already have an internal Bluetooth module, do not appear in the point of it, even a second to put on one of the few USB ports the laptop has.

Fortunately, I have experienced in my previous musical enjoyment no loss of quality - no difference to the cable without direct comparison is also the standard SBC codec. That may be different if you use a Bluetooth headset and / or you listen much more accurate - but if it is only a matter zuzuspielen music on the system, without having to stretch a cable, the device is just right - and the extra money well laid out for the better antenna.
