Review: Solid Everyday Wired Earbuds That Get the Job Done - I picked up the Sennheiser CX 300S black ones because the free earbuds that came with my phone were sounding thin and the mic was useless for calls. I wanted something simple, wired, with a remote for play/pause and answering the phone, that I could use on the bus, at my desk, and for short walks without spending a lot. These are basic in-ear buds with a flat cable, one-button remote, and four pairs of tips so you can try different sizes. Once I found the right tip size they seal pretty well and block a decent amount of outside noise for a passive pair. Sound is clearer and more balanced than the cheap stock ones—vocals come through clean, and there’s enough bass for most music and podcasts without it getting muddy or tiring after an hour. I use them for commuting, listening while working, and taking the occasional call. The mic is fine for everyday conversations; people can hear me clearly in quiet or moderately noisy spots. The one-button remote works for play/pause and calls, which is all I really need most days. The cable doesn’t tangle as easily as round ones, and the right-angle plug is practical. They come with a small pouch, which helps keep them from getting scratched in a bag. On the downside, fit depends a lot on your ears. The tips that worked for me might not stay put for someone else, and a few people mention they slip out during movement. The single button means no volume control on the cable, and track skipping can be hit-or-miss depending on your phone. Durability is mixed—some folks get years out of them, others report the cable or one side going after a few months of daily use. They’re not meant for workouts or rain either. For the money (value for money), these deliver better sound and a usable mic than most free or ultra-cheap earbuds. I expected a reliable daily driver that sounded clearer and handled calls without hassle, and they mostly met that. Not the most feature-packed or bombproof pair out there, but they do the practical stuff I bought them for without drama.
Review: R6/Beaulo/Xbox/Bass - I have headaches so ear buds and iems is the way for me. With that being said I’m a competitive gamer on Xbox who plays rainbow six siege. For years I’ve heard about these earbuds. Beaulo A pro rainbow six siege player used these for years before moving over to Bose qc. They were called the senheiser 3.0 now the try are called senheiser 300s. I believe the difference now is having a built-in mic. I was unable to find any information. So I have to go purely off my experience. Firstly the fact that these are so light with this powerful a base is actually crazy. I was under the impression the bigger the earbud the more bass, well that’s just not the case with this earbud. Extremely light Powerful bass ( having the right fit tip fixed this) Now for the most important part which I think I’ll have to update later. The soundstage. It’s such a wide open soundstage I wasn’t used to it because I’ve been using cheap turtle beach battle buds. And Before you lose your mind on that here’s my experience on past earbuds. Tin t2 very accurate but too high pitch Blon 03 awesome bass but not accurate soundstage. HyperXcloud falls out of ears Rip OK now back to the turtle beach battle buds. These are so underrated The bass and the soundstage are so good for gaming hell anything music movies etc. my problem with them is they’re very bulky and get uncomfortable after some time and the mic is terrible always getting complaints about how people can’t hear me or whatever. In actuality it’s my fault because I don’t use the boom mic because that’s more pressure on the ear. OK now back to the Sennheiser 300s These are the only earbuds to ever compare to my turtle beaches my only problem is I’m not used to the sound stage yet. Even if I end up not using these for competitive R6, i’m probably gonna use this with everything else just for the simple fact the base is so exciting and it’s so light and I don’t even feel like I’m wearing anything. If I’m able to update I will give an update on the soundstage and how well they work with Rainbow six siege. Sorry for the long write, but I figured I should share my hundreds of hours of competitive FPS earbuds experience, Especially since there’s such little information out there. Update not good for R6 on Xbox. Turtle beach earbuds still king.

## Questions & Answers

**Q: Does it have a microphone and how good is it?**
A: Works well on my phone and PC for taking calls at least.

**Q: One customer claims it has volume control. 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

### ⭐⭐⭐⭐ This is mainly about silicon tips
*by G***O on October 25, 2019*

So, I'm not fond of writing negative reviews, and I really am fond of some of the things regarding these headphones, but.. Here we are. Some positives: 1. It looks very nice, I like the color and style 2. The medium size silicon buds are relatively comfortable.. After some initial adjusting, they're really good tips! (I will call them tips from this point on) Negatives, and why I'm writing this review: 1. The sound quality is.. Off. Specifically, I think there's something off about the bass. 2. While it's comfortable to wear, it was actually kind of painful to put in my ears at first. The tips were a little stiffer for some reason. They do soften up after time though, and then they're great. 3. The silicon tips... Fall off sometimes. I've don't know how, but I've rarely had this issue with other headphones. It's happened several times, and I eventually lost one of my medium tips (right ear). 4. The replacement silicon tips are.. Okay. The small one is the size I chose after the medium, and they look any form of noise cancellation, which means that it's harder to block out sounds if you're in any public space (say, a coffee shop). One of the small tips also fell off (left ear) after a few days of use. 5. I've looked around for replacements for these tips for some time, and Sennheiser only seems to want you to buy different tips from a company called Complyfoam, which... Is expensive. I just wish I could get a replacement for the ones that came with these headphones. Overall, the headphones aren't bad (though not worth the $50 price point, I'd say they're valid at $20). If you get these, just keep an eye on the silicon tips!
