I love it.... I had a decent budget of £100 for headphones. Bought the Aria pro to begin with at £90 but the quality was not up to the mark, it creaks, the sound leakage was bad with others in the room complaining and the sound was just ok, as soon as I heard them i felt like it was lacking in bass especially low end bass. So decided to return it and took a chance on the q20 as it was no 2 or no 3 on amazons top selling and I alo thought to try the tribit tune as they're similarly priced and come highly recommended for sound quality.The build quality on this is great no creaks, the sound is marvelous! The bass goes real low, mids are rich especially lower mids, highs are well rolled off making listening for long periods comfortable. The Tribit on the other hand has highs that can be a bit tiring and the bass on the tribit doesnt go as low. I find the bass in the q20 much richer. The tribits are louder though and the tribits sound clearer with a slightly larger soundstage. Overall if bass is important to you, you will love these over the tribits. If highs are more import to you then the tribits are better. The Aria pro I cant recommend to anyone for sound quality. The fit was a bit too tight initially but now after 2 days I guess they've 'broken in' and are comfortable, i find them more comfortable than the tribit but less so than the Aria pro but theyre not bad. The noise isolation (not noice cancellation) from the foam cups is excellent! I find it better than the tribit the tribit is already good but this takes it up a notch and is sometimes better than using ANC as the noise isolation is good sound leakage is minimal. The Aria pro was the worst in this regard.ANC is good on these and i couldn't hear the tap running while doing the dishes or even the vaccum cleaner. But using ANC results in a degradation in sound quality on these. Also if you're in a silent room and you switch ANC on you will hear white noise more like wind/flowing water and i recommend keeping ANC off when listening in a quiet room. With ANC off the mids are richer and overall sound is fuller. For me sound quality is more important than ANC and these just do it right when it comes to sound. Probably drivers that are capable of a wider frequency range make these richer sounding than other budget options that I have tried. The Bass up implementation is absolute rubbish and it severely degrades sound quality it would be better if the low end rumbled or went deeper with this switched on but instead mid bass is boosted and you lose clarity in the mids and highs basically bass is now everywhere in every frequency and voices become recessed and move to the back.Haven't owned it long enough to comment on the battery but it was 60% when i got them. I spent 2 - 3 hours listening and it was still 60% so overall battery must be good.Another minor niggle with these is when the volume is full and you try to raise it further it interrupts your music and beeps to let you know that volume is full. Just a small beep without the interruption would do.So of the 3 I bought I will be returning the Aria Pros (the most expensive) will definitely be keeping these and still thinking about the tribits might test them a bit more before deciding on whether i keep them or return them. They do have a slightly different sound signature and it could be worth owning both. If you like your bass to go low and want good sound quality on a budget i would recommend these. Under £100 id be surprised if it gets better than these.Update1: I returned the tribit tune as they were too uncomfortable to wear for more than an hour, guess I have big ears. Also the sound quality was not as good as these to me so didn't make sense keeping them. Id rather save that money and put it towards buying a sony xm3/xm4 in future. For now these have satisfied my needs and I will be sticking with them for the near future.Update2: So I couldn't resist and had to know what the fuss was about and got myself a pair of sony XM3s the "ultimate headphones". Trust me guys the difference in sound quality is negligible. The sonys are definitely better when it comes to noice cancelling, premium look and feel and overall design because of its slimmer profile. But when it comes to pure sound quality with the nc off the soundcore is nearly as good. The sound is rich, the bass goes quite low and lots of detial is present. Highs and mids are well rounded. With the sonys on the other hand the higs and mids sound a clearer but a bit sharper/shrill at higher volumes. The low end bass is less audible but bass overall is really tight and punchy.. rather than be audible it creates these waves you can feel on your ears like a rumble..where as on the soundcore the low end bass is more audible but it doesn't create this rumble its the best way i can describe it. Overall when i put on the soundcore i never feel like i miss the sonys these are a perfectly satisfying pair. They've even gotten more comfortable over time. In fact the sound leakage is better on the soundcore and i can use it when people are sleeping around me without disturbing them. Also thr plastic on the soundcore feels thicker and will gather less scratches and fingerprints makes it great for a beat around pair. For 40 bucks they're a steal. If like me you want a good pair of headphones but are wondering if the sonys are worth it... Well they do offer a lot of good things but if sound quality is your only criteria and you like a warm but detailed sound signature then the soundcore will certainly satisfy your needs but only with the nc off. With nc on the sound quality does deteriorate. But overall i would highly recommend the soundcore to anyone.
