My original order got lost and they were so kind as to send a replacement long after I had given up on ever getting it. I'm now the proud owner of both E1x2 OTG & E2x2 OTG interfaces, along with other DAC/Amp gear I've bought from them. Thanks!!! Review: Clean Audio and Simple to Use - Works flawlessly. Clean output. The gain is just enough for an SM57 to run live output. Headphone output power and clarity is incredible. One annoyance is that they haven't fix the exponential gain knob, you have to be super precise in the last few degrees of rotation to avoid clipping. I paid $169, and there is nothing that comes close at that price from a pure hardware performance standpoint. Have not yet tested the OTG with my phone, so I might revise the review if that doesn't work well. ## Features - 【High-Quality USB Audio Interface with Optical Output】 The TOPPING E2x2 OTG USB audio interface delivers high-resolution sound with support for 192kHz/24bit recording and playback.

My original order got lost and they were so kind as to send a replacement long after I had given up on ever getting it. I'm now the proud owner of both E1x2 OTG & E2x2 OTG interfaces, along with other DAC/Amp gear I've bought from them. Thanks!!! ### ⭐⭐⭐⭐⭐ Clean Audio and Simple to Use *by P***H on December 6, 2025* Works flawlessly. Clean output. The gain is just enough for an SM57 to run live output. Headphone output power and clarity is incredible. One annoyance is that they haven't fix the exponential gain knob, you have to be super precise in the last few degrees of rotation to avoid clipping. I paid $169, and there is nothing that comes close at that price from a pure hardware performance standpoint. Have not yet tested the OTG with my phone, so I might revise the review if that doesn't work well. ### ⭐⭐⭐⭐ Great audio interface *by T***R on October 17, 2024* This is a really well designed audio interface. It's overall look and feel reminds me of classic 2x2 audio interfaces of the past. The knobs feel really great and it has multiple knobs, which is great. you don't have to click a button to active then turn the one knob that is on the interface like other interfaces do. So you can quickly adjust levels with ease. The overall sound is great and the preamps are nice. I have tested these and should have enough power to drive even something like the sm7b. The headphone output is really great and loud and packs plenty of power. The overall feel of this interface is nice, a flat black matte finish does not pick up finger prints and gives it a professional feel. This does not include any recording software but it makes up for that with its control software of the interface. With that software you get different mixes and virtual playback routing options, loopback and OTG, so you can connect your phone or ipad and stream audio between the 2. The one downfall but seems to be a tread lately is that it is USB-C but if you are using it with a standard usb cable, it will require you to use an additional usb-c cable to provide it power. Not a big deal just be aware. Overall I would recommend this interface for small recording at home or if you travel around and want something to put in your bag to use. It does require some extra power with non usb-c devices but it does offer an on and off switch. ## Frequently Bought Together - TOPPING E2x2 OTG USB Audio Interface - Ultra-Linear Preamp & Powerful Headphone Amp,Optical Output, Dual Mobile Streaming, Zero-Latency, 192kHz/24bit Recording, PC/Mobile Compatible (Black) - beyerdynamic DT 990 Pro 250 ohm Over-Ear Studio Headphones For Mixing, Mastering, and Editing - Shure SM7B Microphone - Vocal Dynamic Studio Mic for Broadcast, Podcast, Recording, Gaming & Streaming, XLR, Rugged Construction, Detachable Windscreen, Smooth Sound, Warm Vocals, Wide-Range Frequency --- ## 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/653737384-topping-e2x2-otg-usb-audio-interface-ultra-linear-preamp-powerful](https://www.desertcart.be/products/653737384-topping-e2x2-otg-usb-audio-interface-ultra-linear-preamp-powerful) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-26*
