Featuring dual headphone outputs and a versatile docking base, this amplifier is designed for audiophiles seeking high-quality sound and convenience. ## Description The Fiio E09K Desktop Headphone Amplifier with E17 Dock In is designed to work with the Fiio E17 USB DAC Headphone Amplifier and USB soundcard. It features dual-channel power outputs for both 1/4" and 1/8" headphone plugs, as well as an additional RCA L/R audio output, USB interface and line input. The amplifier features a Texas Instruments main power amp integrated circuit with a low noise level, low distortion and a high conversion rate. The E09K is cleverly designed with an E17 dock for using the line out signal from the Fiio E17 docking port. This provides better sound quality and makes the amp able to drive high impedance or low sensitivity headphones -- giving you the clarity and punch to make your music sound alive and vibrant. Plus, it lets you charge and sync the E17 with your computer as well. The E09K even has a Low/High gain section switch, LED power indicator and a built-in power converter to meet the demands of high dynamic signal processing. Based on the Fiio E9, this updated version allows for synchronously working for power supply and turn on/off. When using with E17, it only needs to turn on/off E09K, and E17 will turn on/off at the same time. When selecting AUX IN and DOCK IN signal of E09K, there is no need to take out DOCK from E17, you just need to adjust the switch. The EO9K features reliable, durable RCA gold-plated terminals rather than 3.5mm connectors. Other than these updates, there is no tone quality difference between Fiio's E09K and earlier E9. ## Features - Device uses a Texas Instruments TPA6120 Integrated Circuit, which is their main power amplifier IC with a low noise level, low distortion and a high conversion rate - TI OPA2134+TPA6120 chip combo allows the headphone amplifier to have low noise, low distortion and high power - E09K and E17K with Gold Plated RCA-to-RCA connector cable included.

The E17K does not dock in the E09K. Don't order these together unless you are sure they are sending you the E17. ### ⭐⭐ 2.0 out of 5 stars Crapped out in one month's time. E17 will not charge fropm either port. *by T***M on Reviewed in the United States on February 24, 2015* So far so good. I received these items just last week. They both are working and do a fine job cleaning up the signal going into the headphones. It's a much cleaner, clearer sound, no noise in the silent places and helps push the less efficient headphones where they need to be. I found the portable to really help the sound coming from a phone. It does add size, bulk and weight to the phone, but if you have a set of favorite headphones that need amping, these do the job. The bottom piece stays at home connected to the computer (you could also attach this to an existing stereo) and also has plenty of power to push my Alpha Dogs, Sennheiser 558's, and Philips Fidelio x2s. There are more expensive headphone amps and portable amps out there, but really these fill the bill with nice clean power. I would recommend these if you are looking for both types of amps and want something reasonably priced without giving up performance.UPDATE to above review; In exactly one month's time the portable amp E17 has stopped taking a charge. Neither the dock port or the plug-in. As Amazon does not want to deal w/ questions of repairs/replacement the ONLY option given was to ship the whole order back to them for replacement. I wish, at times like these, there was a person, a tech/repair guy, to speak with. Now I cannot recommend either the E17 or the purchase of complicated equipment through Amazon. I will certainly get another portable amp, just will buy it locally where a salesman, tech team can step in and help w/ small repairs. ### ⭐⭐⭐ 3.0 out of 5 stars BE AWARE THAT DAC DOES NOT DOCK TO THE AMP. *by E***E on Reviewed in the United States on March 18, 2015* BE AWARE THAT DAC DOES NOT DOCK TO THE AMP. The picture is misleading, although the product numbers in the text are correct. Think of this as a bundled package with a separate headphone amp and portable DAC. But the two do not work together as pictured. This is OK for my purposes but I was disappointed. Both items I received are in good shape and confirmed as genuine FiiO on the FiiO website. A good deal if you are OK with a separate amp and DAC; look elsewhere if you need the integrated pair. --- ## 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.be/products/9938813-fiio-e09k-high-output-desktop-headphone-amplifier-with-e17-e17k](https://www.desertcart.be/products/9938813-fiio-e09k-high-output-desktop-headphone-amplifier-with-e17-e17k) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-29*
