NeoteckPortable 3.5mm Headphone Amplifier with Bluetooth 5.0 Receiver, Two-Stage Gain Switch, 16-300 Ohm HiFi Earphone Amp, Aluminum Matte Surface

Pros:SERIOUS volume boost, clean/clear balanced sound amplification that is more than loud enough & I seriously mean loud enough, probably to loud/powerful for a wide range of earphones, earbuds, headphones & IEM's, compact enough to be portable & pocket friendly, tactile volume control, can be "hardwired" as well as Bluetooth ability. Bluetooth pairing is simple, easy & stable within 20ft, almost 30ft with no obstructions, 2 stage gain switch is definitely noticeable when switched from L to H, very lightweight, easy to use. Decent battery life. Metal shell. Good build quality.Cons:This an amp without a DAC, no play/pause or track control, charges micro USB not Type-C which is a subjective con on my part, many ppl won't even care & have at least 40 spare micro USB cables these days..., might be too big,/not compact enough for some. Battery life: should be better/longer; considering the size of device. In my opinion it should have a bigger battery... should be closer to 24hrs or more not the 8hrs in the description. Bluetooth range could be better & should be considering it's big enough to accommodate a bigger/stronger Bluetooth antenna..bluetooth signal starts to breakup after 20ish feet & can also be disrupted entirely if objects are in the way of signal (ie: walls, more than 1)Would I suggest or recommend this device to others looking for a Bluetooth headset amp?Overall, Yes. Definitely.Bottom line; if all you're looking for is "more power/higher volumes" to your audio headgear.. You've found it. To that end it preforms Fantasticly...it can easily get more than loud enough to give the user an urge to want to turn it down a bit. I don't see a person needing to deal with Bluetooth signal issues all too much when considering it will most likely be worn "on person" with a wired headset via phone or mp3 player with or without Bluetooth & not used at a distance.The sound quality is balanced, full, rich & lively. It amplifies the sound given to it. That said it's up to the device the signal is originally coming from to "filter" or clean up the signal. Highs are clear, crisp, technical & articulate. Bass is super solid & not "muddy" drowning out mids or highs. Mid-range is smooth & rich. Vocals are forward/front center. Staging is more detailed & wide when being used with higher quality headphones/IEM's. The device is very lightweight & compact enough to not be noticeable on your person unless you don't have pocket(s) that can accommodate. Volume control is user friendly & simple unlike a button (that's purely subjective on my part. I prefer a knob over a button)Take note that this amp potentially has enough power to actually burn out/"fry" cheap earbuds & headphones. If you're looking for something with more features than just volume control or want to use at a distance.. this might not be for you.

Das Gerät wird täglich für ca. 5 Stunden zur Verbindung zwischen einem Laptop und In-Ear-Phones (16 Ohm) benutzt und die Kapazität des Akkus ist noch nicht erschöpft. Die Lautstärke ist vollkommen (mehr als) ausreichend und der Klang ist gut. Das Gehäuse macht einen soliden Eindruck. Schön wäre allerdings, wenn eine Ladezustandsanzeige mit verbaut wäre.

A very inexpensive upgrade . You can hear the difference, even with mid-priced cans. I tested this a pair of AKG, Beyer Dynamics and Sony XM5 headphones. It is not very fond of wired systems. The DAC doesn’t make sows’ ears into purses, and my £12.99 pair of headphones bought at a service station still sound awful. However, it really made the Beyer Dynamics sing, with tighter bass control and clearer vocals. I wouldn’t recommend for Hi-Fi , as they didn’t do the Sonys any favours,But I’m guessing that people who buy the best in headphones wouldn’t need a DAC or would buy a much more expensive one.I tested this alongside a FIio amp/ DAC and a Hip-DAC 2. Yes the Hip-DAC wins in test every time but at a price. However, this is a very worthwhile investment if you want to look the part but your bank has lost all patience with you. On the other hand, it has Bluetooth connectivity and is discrete enough to hide in a pocket.Use with mid-priced headphones for a real treat; don’t expect miracles with cheap cans and, if you are considering expensive ‘phones, you need to factor in the cost of a DAC in your budget. Have fun!
