Compatible Bluetooth Adapter Receiver for Bose quietcomfort 25 Headphone (Black)

TLDR: Worked great, BT pairing is simple, sound is as good as wired. con: volume/track button control isnt great. Overall, I'm satisfied.Like most of you, my phones and tablets have all migrated to Bluetooth. I've had my QC15 for close to 10 years and still love them. I've tried a few other brands, but the QC15's light weight & comfort cannot be matched. And the sound has always been very good. But wired connections are disappearing. So on Black Friday, I purchased refurb'ed Bose QC35 and am fairly happy with them. Really nice BT pairing, sound is good, not quite as comfy. Then, a few days ago I stumbled across the Transeca QC15 BT adapter and I had to try them. I was shocked, LOL, I had no idea an aftermarket QC15 BT solution wass available and for $30, it was worth a try. When they arrived, (impressively and securely packaged) I charged them up and read thru the included instructions. I have to give Transeca credit, they appear to be very customer-centric, quoting Sam Walton, guaranteeing 24 hour response, 12 month free replacement. But the payoff happened with I plugged in the adapter into my QC15s. The BT paring was simple. I tried a few of my favorite rock songs and a couple of loud & high-paced action scenes. The sound was excellent. I couldn't tell the difference between the wired and BT connection. so for amy main critique is the volume/track button. it is a rocker switch, and controls both functions. A quick press jumps to the next track and a longer press changes the volume. I haven't been able to control the volume effectively. I end up skipping tracks or the volume jumps up/down too much. I'm using the controls on my phone instead. Also, the buttons are a bit undersized. So far, no regrets. I'm glad to have the option to use my QC35 and get some additional use from my QC15. I haven't had a chance to test battery life yet but will update when I do.

Update 10 months later. Eventually the adapter stopped charging. I contacted the seller and they immediately refunded me so I bought another one from them.This new one is different than the first in one important way - I now get more than 30 hours of listening per charge! Everything else seems the same but the battery life is WAY, WAY UP. Fantastic.This is the second brand of bluetooth adapter for my Bose headphones I have owned, and I prefer this one over the Myriann. This unit pairs more reliably across multiple devices. This unit has buttons and controls that have quality feel to them; you know when you click a button instead of it being a vague, spongey feel. The sound is excellent with the Transeca unit - noticeably better than the other brand. Battery life is about 6 hours on each charge.Two minor nits I would change? The voice that announces "pairing" or "power off" is robotic and grating. And finally, it would be worth real money to increase the battery life to 10, 20 or even 30 hours per charge. At that point it takes the worry out of using them. Again, a minor nit when you consider that you are breathing new life into your old favorite Bose headphones.This unit works well and is a good value at the price. Don't hesitate in choosing this one.

If you're looking for the cheapest bluetooth adapter for the Bose QC15 on Amazon, you've found it.Summary:Pretty typical bluetooth performance. Terrible call microphone quality.Sound:I'm not too impressed by the QC15's sound in the first place but I feel like this device doesn't alter your audio other than anything standard bluetooth audio typically takes away.Battery:This device would last me idk 4-5 hours if i had to guess. Something like it wouldn't last a whole work day but long enough to not be annoying. Same thing with charging — pretty typical i guess.Call quality:Everyone I've called through these headphones said it sounded like I was far away from the microphone and I was hard to hear. Given that, I don't even know if the microphone works. Everyone over the phone sounded fine to me and pickup worked fine. Turning the bluetooth headset off automatically hangs up the call which is annoying.So, if you are really banking on using these for answering calls, I would strongly recommend looking for another product.Extra:I wish the charge port was on another side since the first time I plugged it in, the plastic device strained a little bit without me bracing the opposite side.I don't mess with the volume buttons on the device since, literally having a device that makes these headphones compatible with my Iphone with minimal audio differences is the biggest reason for this purchase. I'm satisfied.However, Ive seen $10 bluetooth adapters perform the same if not better on other headphones. So, even though this is probably the cheapest bluetooth adapter for the QC15, It's still a little bit overpriced. I can't argue though. Just saying.
