Sounds great and I don’t have to use headphone’s bluetooth signal... through the back of my head...for hours... binging”the expanse” on prime. Some reviews say nx4 sounds bright, but I hear rich and warm. you know its a well liked quality product because there were ZERO black fri/cyber mon deals on these ANYWHERE, or for any headphone amp. they’re great and portable. just buy them. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Quality components and construction. Sounds good as well. *by K***N on Reviewed in the United States on October 22, 2020* Was surprised with quality of construction and components. Made several measurements and all was good. Also looked at battery circuit and the appropriate safety circuits are in place and the battery capacity was spot on. Sounds good as well and is also easy to use. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great headphone amp *by R***Y on Reviewed in the United States on March 17, 2020* Works very well with my Hifiman sundara. I really like the bass boost as it doesn’t boost midbass so much as others I have had. --- ## 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.tn/products/148875258-kguss-topping-nx4-dsd-xmos-xu208-chip-dac-es9038q2m-chip](https://www.desertcart.tn/products/148875258-kguss-topping-nx4-dsd-xmos-xu208-chip-dac-es9038q2m-chip) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-04*
