  1. Rik Dangerous

    Wow. I was desperate to find some wireless headphones that were comfortable and wouldn’t fall out when I am running and the Flex works great. I don’t know Ausounds but so was expecting a boom-tizz (US/Beats/Dre) sorta OTT sound, but these headphones are superbly smooth and detailed with really good balance – much more like a good set of HiFi cans. Noise cancelling is pretty good on droning noises but the rubber tips didn’t seal well on my ears (I get this will all rubber tips). swapping for comply foam buds (cheap on ebay, standard fit) really boosted the sound isolation and massively reduced background noise so I ended up listening at lower volume – always a good thing for long term hearing. They sound superb, don’t fall out and last for ages on a single charge. well recommended.

    I wanted to treat myself to a pair of wireless headphones that were noise cancelling, comfortable and had long lasting battery and these ticked all my boxes. Incredible quality especially for the price, definitely recommend these if you’re looking to upgrade your headphones without a massive price tag.

  3. Kate Newham

    I was unsure if the neckband would be annoying at first after my husband purchased these for me, but I think I’ve been converted and the earbuds are sometimes so easy to lose. I have small ear canals so I was glad there was an option of ‘tip’ sizes. They last ages before I have to charge them as well which is a plus. I hadn’t heard of this brand before but I’m glad I have now. Definitely recommend.

  4. David

    I was bought these by my wife for my birthday, I’d never heard of the brand before as they’re new so wasn’t sure what to expect but am actually really impressed by the comfort and quality of these headphones. They look stylish without being too OTT as well and the sound is amazing.

  5. Lizzie Banks

    I absolutely love these headphones, I’ve never heard sound like it – must buy! now!!

  6. Megan Locke

    If you’re looking to upgrade your wireless headphones to something with some further support and comfort then I highly recommend these! I’d heard of Ausounds from America and was really excited to try them out when they came to the UK, so glad I did as I was not disappointed! The sound quality is amazing and the additional neck support/foam buds are so comfortable and cushion your ears whilst moving so they’re great for exercising, especially whilst doing cardio, no more dangling wires!

  7. George Masters

    These are such a luxury set of headphones. The sound quality is unreal, the balance of music playing into my ear is perfect without it being tinny or too bass’y. The comfort they provide whilst wearing is next level, very lightweight and with the added support to ensure they stay on throughout different activities such as golf, in the gym or using for work purposes.
    These are a fantastic product worth every penny.

  8. Jaz Placemount

    Exceptional quality earphones. I originally bought these to use for personal use but as they’re so good I’ve started using them professionally. I work in the music biz so it’s a hard sell to get me to swap any products I use at work, but these did it for me!
    Ultimate comfort, easy to use and A++ sound quality

  9. A Clarke

    Soo comfortable. The way music sounds through these is the best I’ve ever heard.
    Deffo buy these!

  10. Nathan Harding

    The quality is amazing, they are also the most comfortable earphones I’ve ever used. Get these now, i love them.

  11. Mitchell Connor

    Love love love them. Music quality that is just class.
