Review: Sounds good. Metal casing. 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.

### ⭐⭐⭐⭐⭐ Sounds good. Metal casing. Seems sturdy
*by L***P on December 20, 2025*

### ⭐⭐⭐⭐ Great Choice for Recreational Use
*by R***H on January 2, 2020*

I previously owned Skull Candy Ink'd headphones, but the microphone broke. 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.
