Review: Brilliant little wireless earbuds! - The cost to value here, is insane. I workout on my treadmill for cardio and my bench for weight training and they are great. Love the case and charging LCD screens. Highly recommended for the price and if you need a good pair of affordable workout earbuds.
Review: Noise Cancelling Effect if Different but Appears to Work Well - These earbuds are comfortable and fit comfortably. I bought them for the noise cancelling feature, which was absent on my previous earbuds, causing problems when listening to Audible books whilst walking the dog along roads. I was expecting a performance something like my noise cancelling headphones, which shut out all external noise very effectively. However, these appear to work differently, because they don't cut out external noise but stangely I do appear to be able to hear my book far more effectively despite the background noise, than I did with my previous earbuds. which all but the loudest external sounds - it's almost like these filter the required sound to emphasise it against the background. Strange but effective
