# Hi-Res Audio Smartphone Adapters The Acoustune ATX001 Supports aptX Lossless and LDAC By Michael Hemsworth | Published 2026-05-30 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/acoustune-atx001 References: [t3](https://www.t3.com/tech/iphones/acoustune-atx001-can-add-aptx-lossless-to-your-iphone) & [acoustune.co](https://acoustune.co/products/atx001)  Accessing high-resolution audio has become more important than ever for a wide range of consumers, so the Acoustune ATX001 has been developed to offer a simple, intuitive way to enable it. The device works by being plugged into the USB-C port on a smartphone where it will go to work offering access to [Qualcomm](https://www.trendhunter.com/trends/fiio-bt11) aptX Lossless and LDAC audio. The adapter is powered by the Qualcomm [QCC5181](https://www.trendhunter.com/trends/active-noisecancelling-earphones) audio chip that will bypass and boost the audio processing capabilities of the smartphone to enable access to advanced audio codecs. This is made possible when the smartphone is paired with a set of headphones that support the audio codecs. The Acoustune ATX001 also features its own USB-C input to accommodate passthrough charging during audio streaming.
