Built-In Battery Long-lasting internal lithium polymer battery lasts up to 20 hours and recharges through convenient micro-USB port (micro-USB recharging cable included). Why would I need a headphone amplifier? Headphone amplifiers can be great for anyone looking to get the most out of their favorite pair of headphones and improve their overall listening experience. Cell phones, tablets and other listening devices these days may sound ok for general use, but could be lacking in overall response. A good headphone amplifier can improve the frequency response, clarity and add a much needed volume boost for high impedance headphones. They can also help in loud environments where it may be necessary to turn the headphone volume up more than normal like playing drums to a backing track.

Will not work on anything that has a built in amplifier. Instead of spending 20 on this, spend 10 on a boomstick and get more bass. ### ⭐⭐⭐ Worked great while it lasted. *by A***H on Reviewed in the United States 🇺🇸 on December 23, 2018* I bought this in July and by December it no longer was functional. For the time that it worked it was great ### ⭐⭐ the boost in volume and tuning of sound are not worth the extra work for me *by A***R on Reviewed in the United States 🇺🇸 on January 29, 2019* as an amplifier the increase in power was insignificant to the ear in regards to loudness, as for audio improvement the highs were higher and the lows were more pronounced but the balance seemed off. i don't think the average listener will use it continually and a audiophile would probably prefer something better balanced or adjustable --- ## 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.pt/products/54969688-shinevi-portable-headphone-amplifier-black-180mw](https://www.desertcart.pt/products/54969688-shinevi-portable-headphone-amplifier-black-180mw) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-22*
