    Good buy
  

*by P***L on Reviewed in the United Kingdom on 7 March 2021*

They have become my go to headphone. A fun listen that never gets tiring. Changed the pads to Shure 1540s and for the price, they’re hard to beat

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Best headphones I have ever owned
  

*by F***N on Reviewed in the United Kingdom on 21 April 2019*

Sound great and have a brilliant build quality. Replacement pads are a must though as the stock ones are very thin.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    These are definitely the ones for bass
  

*by S***W on Reviewed in the United Kingdom on 26 July 2016*

I tried the T50RP MkIII and even though they sounded amazing, I was missing a decent level of bass. Don't get me wrong, I was reluctant to return them as they really are quite addictive to listen with. I ran them through a little dot mk5 dual mono with poweramp installed on my Samsung S7. Tweaking poweramp brought out the best of the available bass. Mids and trebles were superb. Non fatiguing. I read what little to almost no reviews of the T20's. Then asked a few headphone dealers about the bass on the T20's compared to the T50's and even the T40's.  They were all in agreement that the T20's had the best in sub bass to compliment the clarity of the vocals. I took the plunge (again) and bought the T20 MkIII. It definitely paid off in dividends for me. I'd already purchased the Shure alcantera 1540 earpads (at ridiculous expense from the USA) to fit on them. Tweaked the settings in poweramp again. This time REDUCING the bass and slightly raising the treble. The bass is outstanding on these. No mistake. I have Denon (Fostex) D7000. The sub bass on those are hard to beat, going down to 5's as opposed to the T20's 10's, even though the human ear is only supposed to hear down to 20's. Where the T20's shine is the clear but not painfully bright vocals. There is a sacrifice to the T20's compared to the T50's and that is the bass bleeds into the lower mids, but the higher mids are still detailed enough to keep the music interesting. If you prefer mids and highs and a flat bass, get the T50's. They are excellent in their own right. However, for me, I just prefer a more meaty drive and the T20's do just that. The only reason I've given 4 stars and not 5, is because the headband does start to hurt the top of my head after about an hours use. However, after sourcing Shure earpads, I'm going to purchase the Mr Speakers comfort leather strap to remedy this. These T20RP MkIII are staying with me.
