Sennheiser CX 300S In-Ear Headphones - White is rated 4.3 out of 5 by 18.
Rated 5 out of 5 by from Sennheiser CX 300S [This review was collected as part of a promotion.] I am more than happy with the Sennheiser CX 300S. They are an excellent pair of in-ear headphones with great ambient noise reduction, and they also have a built in microphone and remote for call and music control. They provide an excellent level of sound isolation and bass-heavy sound that will please all lovers of drum & bass, hip-hop and EDM. They do require a bit of running in before they perform at their best, but after a few hours of playing music, the high frequencies sound crisp and fresh, and bass notes display dexterity and discipline. I would defiantly recommend the Sennheiser CX 300S for all lovers of high quality music!

Rated 5 out of 5 by from Never regret:) Awesome sound, advanced feature I had heard from others Sennheiser is well known brand and good reputation. This was my first Sennheiser item and i bought this at great price when it was on special. I purchased other brands earphones before but it didnt meet my expectation. I wanted clear sound with some bass. And i did not want wireless one to avoid frequent charge. With no hesitation, I ordered a white one and it came with such a nice package. Different size earplugs let me enjoy more by minimising surround noise. Nicely fit and long enough cable. Box came with small pouch to keep my earphone safely when carried. This is one of the items that i never regret paying and possessing. Sound is clear with abundant bass (enough to me) and design is very neat and advanced feature in my point of view. I am super satisfied with this and carrying it all the time:)

Rated 4 out of 5 by from Great sound, minimalistic control. [This review was collected as part of a promotion.] These in ear phones sound really good. They have silicone style seals in a range of sizes which help eliminate background noise effectively without the need for battery powered noise cancellation technology. The ergonomic angled design of the buds helps them fit easily in to your ear canal. My only reservation is that the cable handling noise can be a bit distracting for me, but only on the move. Sitting still on a train is fine. The pouch the come with is a nice touch too.

Rated 5 out of 5 by from Top Quality Headphones [This review was collected as part of a promotion.] A truly fantastic pair of in ear headphones, the sound quality is the best I have heard, the range is broad and the sound clear, even at high volume there is little to no distortion. The headphones themselves are tastefully designed and subtle when worn under a T-shirt or jacket, and the carry case is a nice touch that minimised the amount of time spent trying to find them in my bag. I was also impressed with the range of sizes in the additional earbuds that were provided.

Rated 3 out of 5 by from Sennheiser - CX 300S a little disappointing! [This review was collected as part of a promotion.] The sennheiser CX 300S in my opinion lacks bass and sounds to tinny. I tried the product with my phone , ipod,and with vinyl ,All had the same lack of bass sound.The ear buds are really comfortable to wear and the product is very well made.Comes well packaged with additional ear buds.There is also a nice pouch with a snap shut design.The adjuster on the cable length works well . Overall the CX-300S is a well made product but sadly not for me due to the lack of bass.

Rated 5 out of 5 by from Good inexpensive earphones [This review was collected as part of a promotion.] Really like the earphones, for the price, it is much better than those cheap no brand earphones. It is not the best, but for the price, it is worth it. I really like the carry case that comes with it, it is easy to open and close to get my earphones. I also like that the cable is at a 90 degree, so when I plug it into my phones and have them in my pocket, it avoids the cable from being bent whenever I bend down and raise my legs (I destroyed my previous earphones this way...). The only downside I can think of is that the control only has one button to play/pause, previous and next song. It doesn't have a button to control volume so I have to use my phone to increase/decrease volume. Other than that, it is an excellent earphone!

Rated 5 out of 5 by from Sound Quality First Approach [This review was collected as part of a promotion.] Whilst the basic external materials point to a lesser price point, it's clear upon listening that the claims of detailed sound reproduction and enhanced bass are where the focus have been. Challenging bass notes were handled perfectly and together with a perfect fit out of the box, the isolation and sound experience was top notch. I like the unassuming look. Just the jack lead means for many iPhone users, the adaptor dongle is required.

Rated 3 out of 5 by from CX 300S [This review was collected as part of a promotion.] I received these recently, to start off for their low price they are acceptable for most, although anyone who does like some integrity in their audio, may find themselves disappointed. Personally the lowend wasn’t strong enough and it doesn’t really have a big soundstage compared to some competition. Often when using these headphones and medium to high volume I find the mid and high range far too intense. The high end can sound particularly tinny when it’s loud, sometimes unbearably so. The build quality is decent, cable seems a little flimsy at the ends. A few features that are lacking would be the neglect for anyone with smaller ear canals the smallest option are still too large for my ears. Additionally there are also no dedicated media skip/precious keys.
