Review: great value for money - after reading other reviews on cheaper products like these i decided to opt for a slightly more expensive pair but without breaking bank on big named brands. The quality build wise is very good. Sound quality is fantastic, i haven't used them with the 3.5mm wire yet and only used them via bluetooth. I use them while playing World of Warcraft and depth of what i can hear is amazing. i haven't used these with a phone as a hands free device etc. Don't make the mistake i made, the 3 holes which serve as openings for the LEDs to show status are duplicated on ear piece which the charge port is, although there are no LEDs behind these holes, i thought that they weren't turning on or charging etc. i high recommend these headphones
Review: Great replacement for Minelab Equinox wireless headphones. - Bought the Golzer BTX40 headphones for use with my Minelab Equinox metal detector. The original headphones would have cost over £100 and yet as far as I can tell the Golzer BTX40 are exactly the same but with a different badge! Work fine for me. They are very comfortable to wear for long periods and hold a charge well. Not sure how long exactly but they saw me through a 6 hour session on the beach without any problems. I have also tried them for music and video. I would say a little bass heavy? but they are definitely as good as anything else for the money.

### ⭐⭐⭐⭐⭐ Great replacement for Minelab Equinox wireless headphones.

### ⭐⭐⭐⭐ Amazing for the super cheap price
*by F***Z on 8 July 2019*

Truly excellent for the price. I own a wide range of headphones from cheaper sports headsets to top of the range Sony over the ear, with B&O, Philips Monster, AKG and Denon in between. I use an audiophile source or DAC and can honestly say that these offer 80% of the quality of a very decent set of £100+ headphones for less than 20% of the price. For me they will be a great set for taking on holiday or when I'm worried about losing or breaking a decent set. They are generally above average headphones, but for the price they are an absolute steal. Worth noting that they take a couple of hours to "run in" - the sound quality noticeably improves during the first few listens.
