Given the combination of the max volume of an ipad and a set of headphones with a very long cord, my sound level was difficult to hear over the exercise machine noise. With this USB chargeable headphone amplifier in the line between the headphones and the ipad, I can get excellent sound well over the surrounding background noise with level to spare. This product comes in a strong metal case not some cheap plastic garbage. Its on/off/volume knob is also metal, as I said well designed and built. In all the time I’ve had it I’ve only had to recharge it twice as its seems to have great battery life. It comes with a short approx 4 inch cord to go from the amplifier to the source and has as its output a 1/8 in standard jack. It also comes with a charging cord to mate with the amplifier and a USB end to plug into any standard USB wall charger. I haven’t tried it yet but I’m betting I can also use it on my professional audio portable wireless headsets for use during my professional video productions as sometimes it gets noisy backstage for our crew members and the audio sets could use some extra boost. Because these are so small they can fit in a cameraman’s shirt pocket or real pants pocket and given its metal sitting on it or dropping it wont smash like cheaper plastic products. ### ⭐⭐⭐⭐⭐ Amplify fine. *by on Reviewed in the United States May 9, 2026* Good battery life. Works fine . Wear on connectors after repeated 3.5 mm removal. ### ⭐⭐⭐⭐ Great for planes *by on Reviewed in the United States September 10, 2025* I was getting pretty frustrated trying to watch movies on my tablet while on a plane. The noise of the engines was drowning out the sound in my headphones. Of course, sitting in the area with the engines outside the window doesn't help much. I bought this amp and have used it a couple of times on trips and it has made a huge difference. The battery lasts at least 4 hours. I say at least because I haven't run out the battery on a trip yet but have spent 4 hours watching movies on the tablet without a recharge, but the battery is supposed to last 12-15 hours.You will notice some degradation in the sound quality, but you get use to it pretty quickly and it really isn't bad. In fact, it's better than I was expecting. It's a no-brainer to use and it's small enough to easily handle while sitting in your seat.I would recommend this to anyone who travels on a plane for vacations/business/etc. ## Frequently Bought Together - Headphone Amplifier, Portable HiFi Headphone Amp 3.5mm Stereo Audio Gain Switch Support Impedance 16-300Ω Headset for MP3/MP4 /Phones/Digital Players/Computers/Xbox one,PS4,PS5 Controller - 2 Pack AUX Cable, (6.6ft/2m, Hi-Fi Sound) 3.5mm TRS Auxiliary Audio Cable Nylon Braided Cord Compatible with Car,Home Stereos,Speaker,iPod iPad,Headphones,Sony,Echo Dot,Beats (Grey) - Belkin F8V234 Speaker and Headphone 3.5 mm AUX Audio Cable Splitter,Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/170482453-headphone-amplifier-hifi-headphone-amp-3-5mm-stereo-audio-gain](https://www.desertcart.jp/products/170482453-headphone-amplifier-hifi-headphone-amp-3-5mm-stereo-audio-gain) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-15*
