In case you're wondering if this makes you sound terrible to the person you're talking to? YES it is awful. I have to yell for the other person to hear me and good luck if there is any noise in the environment. They sound great to me, but does me no good if they can't hear me at all. **Q: Does it come with the microphone or is that a separate purchase?** A: It has the same kind of built in mic that is inside of wireless earbuds. definitely not High quality, but it exists. **Q: Are these Bluetooth 4, 4.1, 4.2, or 5.0?** A: 4.1 **Q: Is there any volume drop?** A: No ## Customer Reviews ### ⭐⭐⭐⭐⭐ Bluetooth to freedom. *by D***E on March 24, 2019* Only four star on sound quality because anything besides a hardline connection you're not getting the best sound quality. Love the freedom this gives me when wearing my headphones, totally worth the purchase price. ### ⭐ not worth it, possibly dead on arrival *by J***S on February 15, 2026* worked with some wiggling initially, then youtube audio would be scrambled and distant but ads audio worked fine. now if any sound is coming out it sounds like transmission interference. less than 10 hours of light use. headphones have been tested with cable and other bluetooth sets, they're still fine. ### ⭐⭐⭐ Decent Bluetooth headPHONES, aweful as a headset *by J***H on March 19, 2019* I love the ATH-M50x and this adds to the versatility of those headphones which is awesome. They make a good solid connection and fit in well with the style. This is the main reason I'm not giving it a one-star review. I'm being generous rounding up to 3 stars. This is really two separate things: 1. a decent bluetooth headphone conversion kit - 2. A failed attempt at a bluetooth headset I'll start with the PROs: - Looks good - Snug fit, but easy to remove (unlike the first version which you had to nearly destroy to remove) - Very good stereo audio quality ****(this is a heavily qualified statement as you'll see later) - No hassle syncing - Reasonable button placement CONs: - Nearly useless on a PC - High quality audio disappears when using the mic - They removed the boom mic option!!!! WTF (built-in mic only) - Mic volume is very low and can't be adjusted - Audio 'glitches' happen more frequently as you get further away For context, I wanted to use this to make calls on Google Voice while listening to game audio and music. For that purpose this fails completely. I cannot blame this entirely on the product because this may be a fundamental limitation of Bluetooth; it is definitely partly due to PC drivers not being optimized. I discovered that I got much better performance on Android than on Windows or Linux. That being said, since I wanted to use this on a PC I'm still going to discuss why that is a horrible idea. I've attached two screenshots from an audio visualization; these aren't very scientific since they don't show decibels or Hz. It's just a spectrogram visualization from foobar2000, but it gives a good depiction of frequency response over time. The lack of precision just goes to show you how obvious it is. Both images show the results of the same sine sweep played via my laptop to the adapter connected to my ATH-M50x and recorded using a stereo field recorder. There's a lot of low frequency background noise this room, so the low end is hard to see. What's obvious is that when you use the microphone there's only about half of the sweep being recorded at all. Everything above a certain frequency is just. gone. To make matters worse there is ghosting of higher frequencies in the lower registry. Long, technical story short: listening to music in this mode is no better than the elevator music being played on hold on a phone from the 1990s. It. is. painfully terrible. Voice calls (for you anyway) themselves are not bad. It's obviously using the frequencies needed for cell phone conversations. When I switch over to Android it even takes at least some advantage of the "HD calling" feature as I can hear higher frequencies during those calls. However, Android does not let you mix multiple audio sources, so listening to music during a call is out of the question. The big problem with using this as a headset on your cell phone is that the microphone is too low. I haven't recorded any test sounds from this, but everyone I spoke with while using them said that I was very quite / distant or couldn't understand me at all until I switched to the phone mic. That means that the only thing these are good for is bluetooth headphones. And while the audio quality is very good when conditions are good, it's not nearly as good at wired. That cuts down the situations where I would want to use large headphones to get less than pure audio quality. There is also periodic glitches or pops/clicks, especially when playing from the computer (both in Windows and Linux). It's much less sever in android. So, this works well watching movies, listening to podcasts, playing games on your phone, or listening to music that doesn't need a lot of low end bass response. That's not a complete list, but it's useful enough that I'm on the fence about returning this (second generation) product. I would not buy it again as I can buy a stand alone bluetooth headset for about the same price that will accomplish the same goals. The ATH-M50x's are quite comfortable though and there's not a lot of options for Bluetooth conversion. ## Frequently Bought Together - EAS Brooklyn Labs, Version 2 Bluetooth Wireless Adapter and Amplifier, for Audio-Technica M50x Professional Studio Headphones, Clear, Aptx, Long Battery - ath m50x 3.5mm to 2.5mm Adapter Compatible with Audio-Technica ATH-M40X ATH-M50X ATH-M60X ATH-M70X, Sennheiser HD598 HD518 HD558 HD595 HD595 HD598se HD569 HD579 HD599 Headphone Jack Adapter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/101863371-eas-brooklyn-labs-version-2-bluetooth-wireless-adapter-and-amplifier](https://www.desertcart.at/products/101863371-eas-brooklyn-labs-version-2-bluetooth-wireless-adapter-and-amplifier) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-06-03*
