Unless I'm missing something, it does not have remote volume control.** A: It does not have volume control per se, but it can be configured. There are +/- buttons on the part of the cord where the mike is. The default on an iphone is those buttons skip the song forward and back. In settings/control center, you can redefine these buttons to use as volume control. I suspect that android operating systems have something similar. **Q: Do these have same length left and right cables** A: Yes. The cables are the same size. **Q: Can I get an answer on exactly how long the cord is?** A: 1.2 meters that's from sennheisers website ## Frequently Bought Together - Sennheiser CX 300S In Ear Headphone with One-Button Smart Remote - White - Apple USB-C to 3.5 mm Headphone Jack Adapter - Apple MFi Certified 2 Pack Lightning to 3.5 mm Headphone Jack Adapter for iPhone, iPhone Aux Adapter Converter Dongle Audio Cable Compatible with iPhone 14 13 12 11 X XS 8 7 --- ## 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.hr/products/145208605-cx-300s-in-ear-headphone-with-one-button-smart-remote](https://www.desertcart.hr/products/145208605-cx-300s-in-ear-headphone-with-one-button-smart-remote) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-22*
