    Absolutely fantastic!
  

*by H***Y on Reviewed in the United Kingdom on 28 September 2016*

So I've purchased and broken many sets of headphones in the past, and when my last pair broke I decided I wasn't going to spend loads of money if they were just going to break. The problem is, I personally want super high quality music pouring into my ears, so when I initially saw these headphones priced at £10.99, I didn't expect much. However, looking at the reviews, it seemed that these were actually a good quality product! What did I have to lose? So I purchased these and I can honestly say that I have never been happier with a pair of headphones before! The quality of the music that comes out of these things is simply amazing straight out of the box! One I adjusted my audio enhancer on my phone and laptop to suit them, I was genuinely speechless when I played some music. You can hear a much wider band of frequencies on these than on my expensive studio monitors! The sub-bass is so powerful you can almost feel it as if it was coming from a large sub-woofer!Also, the build quality is fantastic! It's been a while now and they are still fully in tact (that's an achievement for me). The connector and part where the two cables combine are made completely out of metal, and the anti-stress rubber parts really help to protect the cable as much as possible. The cable it's self also appears to be braided underneath the rubber coating which makes it really strong. Also it comes with a large selection of ear buds - from small to large to suit everyone. There are also two colors, black and red, and I believe I read somewhere that they are for different frequency responses? Haven't actually tested that myself though. Finally, it comes with a little bag as well so you wont lose all those ear buds!Over all I am extremely happy with this product and would recommend it to anyone and will definitely purchase these again when mine finally break/get lost!Just buy it now!

    My Review of the Product
  

*by A***R on Reviewed in the United Kingdom on 19 March 2017*

Fairly good productThe box came in two days and the packaging was pretty good.It came with the earphones, 6 pairs of changable silicone earheads, 1 set of mouldable earheads, a shirt clip and a fabric pouch to store them in. I wasn't expecting this many included items, however it's really nice to have so many options in regards to the earheads.However what are they like?The earphones are make from plastic and are a good weight, I would say the weight falls on average with many other earphones.The cable is slightly thicker then normal and really feels extremely solid and tough, the cables even go slightly into the earphones to furthermore increase their durability I'm sure I won't be breaking the cable in my day to day use and am happy with this factor.The sound is OK, has good highs and good bass from the songs I tested with them, but they're not perfect, the earphone can be quite "tinny" at times, I bought these earphones for there durability so high bass and toned chords isn't really what I'm looking for, though I really would have liked a more defined sound. I tried adding a custom equalizer to the earphones to see if they would help and it really did improve the listening experience, so when buying these know that equalizer (such as the ones in HTCs flagship phones for example) will really help in adding more bass and tone to the earphones.Overall I am happy with my purchase and have a set of earphones that I'm sure will last a very long time. The durability is very good and really feels a lot stronger then my previous headphones that have claimed the same feature. As of the sound, they are good for the average day to day listener however would maybe sound bare to someone who's after the best sound quality.

    Outstanding Value!
  

*by C***P on Reviewed in the United Kingdom on 6 May 2015*

Ok, finally got to give these a good test yesterday due to me spending 4.5 hours on a train. Didn't want to post a review prior to this as it's too easy to post a knee jerk reaction after a 5 minute test.I can quite easily say that these are the best headphones I ever owned by a long shot. I've never been one for buying expensive ones but have always bought in the £10-20 bracket and these wipe the floor with any of the Sony, Panasonic or Sennheiser ones I've had.The choice of earbuds ensures a good fit for everyone and the differing opening sizes cater for those who like to listen to either speech or music (this is my opinion due to the sound difference between the black and red buds).Didn't have anything out of the ordinary providing the source, just a Samsung S5 Mini. Sounded great with a flat EQ, but with a little adjustment for my personal taste, the sound surpassed any expectations which I had. Rich deep bass and crystal clear highs. It was a pleasure to wear them and didn't feel the usual discomfort which I usually get from buds after a lengthy period of use.Can't comment on the longevity of them yet but they appear well made, do not tangle easily due to the construction of the cable and come in a nice handy pouch to stop them getting ruined in your pocket.For the price, I guarantee you won't buy better and I would suspect you could probably pay a lot more for an inferior product.
