Fungerar som förväntat

Funziona perfettamente, 4 canali separati

Habe diesen Verstärker an meiner DVBT-2 Fernsehbox angeschlossen, um nun einen besseren Bass und Höhenit größerer Lautstärke in meinem Over Ear Kopfhörer genießen zu können.Ist zu empfehlen, auch am PC oder Notebook anschließbar für ein besseres Klangerlebnis im Kopfhörer.

Tolle Ware Danke

Klasse Teil. Ich hätte nicht gedacht das das Gerät die gute Qualität auch in der Übertragung hat.

Das Gerät ist hochwertig verarbeitet und die Soundqualität ist recht gut. Jedoch das Knacken beim Ein/Aus Schalten ist übel. Des tritt auch auf, wenn man das Gerät vom Strom nimmt oder mit Strom versorgt. Es ist nicht möglich es zu umgehen.

Sehr Zufrieden und schnell Geliefert.

Ich betreibe 2 Kopfhörer und 2 Lautsprecher am PC-Audio-Ausgang. Die dafür zu schwachen PC-Signale werden nun optimal verstärkt. Alle Geräte können einzeln geregelt werden. Besser geht es nicht.

Bought this to hook up to my computer and play audio to my headphones and speakers from the USB DAC. This makes it super easy to just adjust volume on each independantly without worrying about blasting the volume after a switch or having to manually switch the 3.5mm cable on the DAC.It feels super well built, nice metal housing and volume knobs have a very sturdy feel when adjusting.Great value overall and well worth the purchase

Wirklich effizient gegen digitales Rauschen oder Erdungsbrummen ! Wer sauberes und ruhiges Signal braucht, für ein ungewöhnliches Environment oder auch Situation mit mehreren Geräten, wo es evtl mal zu Problemen kommt, kann hiermit schnell Abhilfe schaffen

Wie auch beim YGiTK 4-Kanal-Stereo-Kopfhörerverstärker, habe ich auch hier ein sehr lautes Einschaltknacken und ein erhöhtes Rauschen (bei angeschlossenen Kopfhörern ohne Signal ) der Drehregler ab 12 Uhr. Auch der Klang war nicht so gut wie beim YGiTK . Wahrscheinlich ein generelles Problem bei derart günstigen Geräten. Für mich leider ungeeignet !

After reading generally-favorable reviews of this item, it's attractive pricing prompted me to purchase one to try. The application in this case is TV-listening, not necessarily privacy, but as a means to better follow movie dialog, which has suffered from a lack of stress on diction within recent crops of actors, and of unwarranted dominance of music and effects tracks during mixdown in post-production. Moreover, the reverberant acoustics of our rather cavernous living room also sabotage speech intelligibility.This amp is packaged nicely; so well, in fact, that Amazon simply slapped their shipping label on the box it comes in. The amp is well protected in a custom-foam 'nest' along with its power adapter. The unit is small enough to nestle between couch cushions. Up to four watchers can share the TV audio, each with independent volume control... which is not only convenient, but necessary, as I found out.We tried the amplifier with multiple headphones, from very pricey studio-monitor types to 'stethoscope' headsets normally associated with dictating machines. The impedance and sensitivity differences between headphones makes the individual volume controls a must. Least sensitive were my go-to Sennheiser HD414s, a good choice for TV viewing from an intelligibility standpoint, although wearing them for more than an hour might be a problem. These were early 'open-air,' 'on-ear' types, now 40 years old. The most sensitive headphones were another Sennheiser 'over-the-ear,' studio-quality ones, which block nearly all outside noise, but are again not that comfortable for extended use.The surprise was the 'stethoscope' set, which pose no problem for wearing hours on end. The audio quality generally isn't that great with this type, but they do excel for speech intelligibility. A neat trick is to leave the normal TV speakers (or surround system) on, which will provide movie effects and music bass response while wearing this type of headset. Be sure to choose one that's "stereo" as many in this category are not (for dictating machines).Another tip: if your headphones have a built-in volume control, operate with that control wide-open and use the amplifier's volume control to set the sound level. That will maximize the headroom margin in the system.As for the performance of this little amp, again, it's excellent. I encountered absolutely no hum or noise attributable to the amp, action of the volume controls is smooth and wide-range, the amp generates no heat, and no problem with intermittent 3.5mm jack connections. By the way, if you are plagued with headphones or other gear that cuts-out as you wiggle those 3.5mm plugs, put a small drop of Caig DeoxIT Gold (sold on Amazon) on the plug. It keeps the connection solid for a long time, not like simply licking the plug... ugh.

Como algo tan pequeño funciona muy bien. Superó todas mis expectativas
