Headphone Amplifier Bluetooth 5.0 Headphone Amp 16-300Ω | HiFi Audio Receiver, Dual Gain, 1500mAh Battery, 3.5mm AUX In/Out, Portable, For Smartphones, Laptops, MP3, CD Players

As someone who's dealt with hearing difficulties since childhood, I've always struggled with the pitifully low volume from standard headphones—no matter the audio source, it just wasn't enough to catch every word in podcasts, movies, or calls. The Neoteck Headphone Amplifier with Bluetooth 5.0 receiver has been a game-changer, letting me amplify sound to comfortable levels without distortion. I bought one on a whim after years of frustration, and it worked so well I recently got a second unit—one for my iPhone during walks and another permanently connected to my TV’s audio output. If you need a volume boost, this is a must-have.What I Love (The Pros):Massive Volume Boost: It pushes sound way beyond standard headphone limits—perfect for my hearing loss. I can now enjoy clear dialogue in films or lyrics in music without maxing out my device’s volume and risking ear fatigue.Versatile Connectivity: Seamless wired inputs for my laptop, PC, or TV, plus Bluetooth 5.0 for wireless use. It auto-connects when turned on—just check your iPhone or laptop’s Bluetooth list, and it pairs in seconds with a solid 30-foot range (no dropouts in the next room).Dual-Use Convenience: Having two units is a lifesaver—one travels with my iPhone for walks, boosting podcast clarity on the go, while the other stays plugged into my TV for movie nights. Both setups are flawless.Compact and User-Friendly: Pocket-sized with simple volume and mode controls. USB-C charging while in use means no downtime—I just plug it in during long sessions.Reliable Battery Life: Each unit lasts 6-8 hours per charge, perfect for daily use, and pass-through charging ensures I never run out of juice.Affordable Lifesaver: At under $30, it’s a steal compared to pricier audiophile amps that don’t add much for everyday needs.ConclusionThis amp is accessibility in a box, turning any 3.5mm wired headphones into a powerful audio solution. I’ve recommended it to friends with hearing issues, and they love it too. Whether you’re boosting TV audio or music on the go, the Neoteck delivers. I’m thrilled enough to own two—grab one if low volume’s holding you back! 5 stars!

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.

I have an older car without stereo Bluetooth audio streaming, so for the longest time I’ve been using a blackberry music gateway and plugging that into the auxiliary 3.5 audio input.That works most of the time, however sometimes, specifically with YouTube playback, the volume can be quite low, even when turned up to the loudest setting on both my iPhone and the car radio volume dial.This solves that problem, and has a very convenient high and low gain switch!That’s a real nice touch, as I typically will keep it on low gain, but then a quick flip into high when I need to play something with lower volume from YouTube or elsewhere.The one drawback is that this thing is battery powered, which is not ideal for use in a car, since your phone won’t automatically disconnect when you turn your car off.There is however a very easy solution to this problem — you can simply open up the chassis / case of this thing and disconnect the battery from the board, which is exactly what I did.The screws are T6 I think, they were very difficult to remove, but I eventually got them out. I wish there was a convenient switch to turn the battery off!But oh well, this works and it works exactly the way I want it to.Now when my car is off, the amp / BT transmitter automatically turn off and my phone automatically disconnects from it, and vice versa when I turn my car on.I keep it plugged in to a car lighter USB port which automatically turns it on when I turn my car on.I subtracted one star for having a Micro B connector instead of type-c, and also for not having an easier way to turn the battery off, and for it being kind of difficult to get the screws out and open up the chassis…but other than that, this product is a great value and does exactly what I need it to do.I do have concerns about longevity, especially with the stupid Micro B connector, but I suppose I’ll just have to be extra careful.The audio quality is just as good as with the blackberry music gateway, it sounds great.I am also using it with a ground loop noise isolator, which is exactly what I used with my blackberry music gateway too.

Although some reviews mention a boat load of negativity, take that with a grain of salt. I purchased this unit a year ago, and have had time to see its pros and cons. I had the earlier version,(still available), about 5 years ago on my Goldwing and was skeptical until I heard what it would do with a stock Honda Goldwing stereo system. Honda put some very crappy speakers(30 amp rated 2 ohm) with very low impedance in these early bikes (2006). Coupled with an amp that did nothing for volume and depth, these were used for many years from 2001-2012 at least. With nothing to lose, I installed the earlier model along with a separate Bluetooth dongle and when I turned it on, the volume and clarity increase was dramatically increased. More bass, way more volume and thru the 4 speakers ,5.25 in, it was easily heard at highway speeds. Before? Not so much past 60mph, and became useless. The new version with BT is on my 2002 model Goldwing now. Same results but without a dongle. Even while plugged in to charge, there is no feed back or hum. Very big difference. Worth every penny, and dramatic difference to our riding even though this bike has only 2 speakers. Before this amp, she couldn’t hear much after 50 mph. Now, it is clear up to 75mph for us both. Give it a try, I can’t say anything about customer service, as I haven’t had issues with product. If it doesn’t work for you, just return it. It’s Amazon, people. Lol

I bought this for my old 2007 Toyota Solara SLE Convertible with the "premium" JBL Nav head until. I found the Aux amplification for this JBL Nav head unit was fairly low (I have a Solara is non-nav to compare it to) and while the head until has Bluetooth, it is only for phone calls (odd decision on JBL/Toyota).First off, It is interesting that it Bluetooth in this Amp is ready to connect as soon as it is powered on, while that surely makes it easy to connect to, I wondering about other random jerks connecting or being able to have a passenger to connect instead of me... I guess time will tell.I have the amp set to low (L), and I just turn it up all the way when powering on, and it is more than enough to overcome the Solara's deficient JBL Nav amplification on the Aux input. I do have power supplied (all times) and while I have a BESIGN Ground Loop Noise Isolator between this Bluetooth Amp & the Aux, I am hearing no whine/buzz. The "old" Amp and separate Bluetooth units I was using before, I did hear a very slight annoying power whine, even with the ground loop noise isolator. It seems all these little amp units could be designed for ground loop noise isolation, it couldn't add that much to the final cost. Anyways, buying a separate one like I did months back, isn't a big deal either.I now have less things to power & various audio/power cables to run in the Aux cubby area - so the cubby area is much cleaner. The size is perfect for the cubby too and as far as I am concern it sounds great. You can't really see it in my cubby, and I love that.

EDIT: I bought this piece of junk TWO (2!) times and BOTH times the headphone jack did not work!! Sound only comes out of 1 ear! Chinese company does not respond to emails, forms, anything. Stay far away from these scammers!Why did you pick this product vs others?:I really enjoyed this amplifier for a while - it was the 1st one I ever bought, thanks to some particularly powerful headphones I recently got. It does enhance the audio quite a bit! However, the aux jack (that we plug into the laptop) is extremely fragile, and now it doesn't work at all, with sound only coming into the left ear. I know it's not a problem with the cord, as I tried both ends; it's an internal problem with the device. Now I need to take it to some repair shop to open and fix it.

I bought this mainly for my car, because it's an old car without Bluetooth. Upon receiving this unit I immediately charged it to full and tested it with my in ears and my Sennheiser headphones. I noticed lots of background noise immediately, and the more you crank the volume up, the louder the noise gets, this can be ignored if you play old music with lots of instrumentation, but for softer music, like classical or any low-volume music, the noise it's there and it's persistent. I know it is unfair to compare this amplifier to something like the Qudelix 5k or the ifi Blue, which I own both and are much more expensive than this, but the sound quality is a night and day difference. I will probably return this one, and get a Qudelix for my car. It's really a shame because the unit is nice and seems promising, but it doesn't deliver quality, just noisy power.

I own the precious version of the Neoteck Headphone Amp which I will say as a basic headphone clean signal amplifier I will give 5 stars. The biggest disappointment with this one is the quality of the Bluetooth connection. It's not lossless, I'm not even sure is apTX, it is Bluetooth 5 however. As a basic headphone amp it seems to work just as fine as their previous version, meaning using a wired source such as your phone's headphone jack (if it still has one), you can plug a 3.5 cable into this amp, and plug some of your High End headphones like my AudioTechnia's or Sennheiser Studio K 240 MK II's into the headphone amp and it will provide cleaner, louder, and more accurate sound than would come from your phone or tablet, or even mini portable music production devices like a pocket operator.Bluetooth Audio Quality:I have been using the previous (non Bluetooth amp) version of this product along with a few years old Anker Bluetooth transmitter/receiver paired with my Sennheiser's and my laptop for gaming. I was so impressed with the amplification of the Neoteck using it this way that when I saw there was a Bluetooth version available I jumped on it, because I could remove the Anker BT device and just use this with my headphones. However, the audio quality and clarity of the Neoteck BT amp are no where near the Anker portable BT in terms of quality. Everything sounds muffled and compressed, and when you are gaming for instance you don't get the same audio separation that I got from the Anker BT. You can choose not to use this amp as a BT device but that defeats the purpose of buying it, and you should just stick with the previous version. Another thing is even if you don't pair its built in Bluetooth, it seems like there is no way to disable the built in Bluetooth device , so this device seems to always be in pairing mode, potentially running down the battery, and also causing unnecessary radio interference, if you already have a fair amount of BT devices in your home already.Final Thoughts:As a basic headphone amp like I previously said the Neoteck seems to be solid and the audio signal is clean and the previous version is probably the best mini headphone amp you can buy at its price range. With this version, don't let the BT feature fool you, its probably better to use a separate BT device plugged into this and get the previous version (still available when I'm writing this) for currently about 10- 15 dollars cheaper. If Neoteck comes up with the same amp but a higher quality audio BT codec i may consider it, but for now this one may be returned, there are better options on the market for a slightly higher price (with buying the old Neoteck plus a different version apTX Bluetooth receiver) but with much better audio to power your higher end studio headphones using Bluetooth if thats your goal.

He400se 'yi gayet güzel besliyor. Herhangi bir sıkıntı, dip ses vs yok. Shuoer S12 taktığımda biraz dip ses alıyorum ancak bu gayet doğal çünkü iemler düşük güç tüketimi ve yüksek hassasiyetlidir. Yani gereğinden fazla güç verirseniz dip ses duymanız doğaldır. Sarjı gayet iyi ve belirtilen sürelere kadar dayanıyor. Kendim sıradan samsung sarj aletinde masada sürekli bağlı kullanıyorum, herhangi bir statik ses yok. Ancak bilgisayarın usb girişine bağladığımda statik ses epey duyuluyor. Kısacası elektriği verdiğiniz cihaz statik sesin varlığı açısından son derece önemli. Şarja bağlı değilken herhangi bir statik ses yok. Düşük güçlerde sağ sol dengeside fiyatına göre gayet tatminkar. Gücü yaklaşık %10-15 i geçtiğinde sağ sol dengeleniyor. O değerin altındayken soldan ses biraz daha az geliyor. Bu elinize gelen üründen ürüne değişiklik gösterebilir. Genel olarak fiyatına göre gayet iyi olduğunu düşünüyorum. En azından markasız dropship ürünü değil. Kendi siteleri vs var kontrol edebilirsiniz.

Pour écouter mp 3 amplifiés

Yes, "Impressive". Wired & Bluetooth both excellent with enough amplification to drive Sennheiser HD 660S2[300ohm] headphones from laptop even at low gain. Sound quality seems neutral with no noticeable distortion, Good solid well finished aluminium case and nice touch that illuminated eoteck logo subdued and not distracting.If affordable, well worth the purchase.

nessuna critica .Ottimo prodotto. Qualcuno a detto di aver difficolta sul collegamento con Bluetooth, posso affermare che nel mio caso uso il ricetrasmettitore Soomfon Mod. BT17 in funzione TX ed il collegamento in area libera supera i 20 metri, all'interno dell'appartamento va benissimo su tutta l'area nonostante le pareti divisorie e le colonne in cementarmato. Pilota benissimo le mie cuffie da 60Hom, nessuna distorsione, io lo uso per l'ascolto TV con ottimo risultato; il ritardo tra immagine e audio èimpercettibile,bassissima latenza. Ottimo prodotto merita più di 5stelle. Complimenti al costruttore.

I waited 4 months before reviewing this, just to make sure my first impressions were accurate.I wanted something to drive a pair of Beyerdynamic DT-770 Pro 80Ω Limited Edition headphones, streaming FLAC audio from my Plex server via mobile/tablet.This little amp is powerful enough to drive 80Ω audiophile/studio grade headphones easily with good loudness at 2/3 full volume on normal gain, and without distortion at uncomfortably loud levels on high gain. There is some very faint almost indiscernible background hiss at high volume levels with music on pause/between tracks, but that seems to disappear as soon as signal is received.Output is very clean/flat/neutral, so much so that I started looking at my Samsung Galaxy tab Android built in Sound Profiles, and discovered that I have measurable hearing loss in my right ear at high frequencies. I now have an 'Adapt sound' profile set up to counteract that.I could try and sound all professional and audiophile, but simply put, this Amplifier paired with a decent set of headphones has transformed my mobile listening. I am hearing details I was never aware of before on music I have owned for years; music that I have listened to on various mid to high range amplifiers (e.g. Denon) and speakers (e.g. B&W) over the years.If I was trying hard to find something to complain about, I can say that Bluetooth range is mediocre, borderline reception at max 10 meters in absolute clear line of sight, but even so much as a dining room chair in between and it is down to 5 or so meters. Really not an issue for me since I have the amp right next to my mobile device, but might be good to know.Others have mentioned the quality of the volume control. I am treating mine with care, and have the amp in a hard case with my headphones when it's not in use.
