Seems sturdy - They sound good but are very uncomfortable for sleeping. I use ear buds to sleep to drown out the annoying snoring coming from my husband's side of the bed. I thought I would try out these Senheiser CX 300S ear buds because they were not too much more than the JBL T290 ear buds I was replacing (for the third time in 4 months making them much cheaper if they actually lasted). I paid $16.99 for each pair of the JBL's and the Senheisers were like $35 so it seemed like a good choice. They do seem durable with a metal casing (which is probably why they are uncomfortable for sleeping). They do sound a little richer than the JBL's which would have made them so much better for sleeping. I am keeping them to wear for streaming or to listen to music during the day. Review: Excellent - If you want good quality speakers, look no further than Sennheiser. You could probably get better speakers if you are willing to pay more for the privilege, but for the price you pay these are good speakers. My music sounds great. They are comfortable. Also the microphone works when I use it for phone calls. And I know this seems like a small thing, but the cord feels unusually sturdy and it really is kind of "tangle-free". Unlike other products I have used, this cord really does resist tangling, and it just feels sturdy. Nowadays, I see many people using those wireless earbuds. If you are like me, looking technology-forward is not your main concern when choosing earphones. I want good sound. And for every dollar I spend, I want that money going into the speakers, not in wireless technology. For me the wires are not a problem at all and I'm perfectly happy to have the wires as long as they come with good speakers attached. I will add that the wires are symmetric, which I very much prefer. I don't like the kind where the main wire goes up to one ear and then a secondary wire goes over to the other year. It's a very good product overall. I've been using mine for a few months with no complaints. I rank this 5 stars for giving me everything I could expect for the money I spent. ## Features - Precision German engineering ensures excellent audio clarity, so you will hear every detail of your music. - Product Note : If the size of the earbud tips does not match the size of your ear canals or the headset is not worn properly in your ears, you may not obtain the correct sound qualities or call performance.

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Sounds good. Metal casing. Seems sturdy *by L***P on December 20, 2025* They sound good but are very uncomfortable for sleeping.

You could probably get better speakers if you are willing to pay more for the privilege, but for the price you pay these are good speakers. My music sounds great. They are comfortable.

I've owned expensive Sennheiser open backed headphones that I love, so I thought I'd give these a try. First off, the construct is high quality. All of the tangible parts feel great and you know they took great care in designed them. The audio jack is skinny and will fit into your phone even if it has a bulky case. At the time, my skull candy earbuds were about $20, so comparing the audio between these and them, I'd say the Sennheiser sounds AT LEAST two times better. Like other Sennheiser products, the treble and base are well balanced, The sound comes in softer than cheaper earbuds and the best way to describe cheap earbuds is they BLURT music instead of it being carefully constructed. Not to talk these up too much because you are buying earbuds. I haven't heard an earbud sound nearly as good as a quality pair of headphones. These are great for recreational use: running, hiking, working out or routine housework. I saw a couple of reviews talk about noise cancellation. you DO NOT get noise cancellation with these. They give you plenty of tips to fit your ear as best as possible. If you have the right fit, its like wearing foam ear plugs and most of the ambient noise is blocked. However, it does not feel like foam earplugs and the ergonomic design fits the ear very well and is very comfortable. Overall for the price, it is a really great product, and if you're like me, you'll use them for years. ## 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.co.th/products/145208605-cx-300s-in-ear-headphone-with-one-button-smart-remote](https://www.desertcart.co.th/products/145208605-cx-300s-in-ear-headphone-with-one-button-smart-remote) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-25*
