Senitek Bluetooth Wireless Adapter for Bose QC15 Headphones | 4.1 Bluetooth Technology Converter Receiver Kit | Easy Pairing, Dual Device Standby Mode, Compatible with Smartphones & iPhones

First 2 day ReviewI just received the Senitek Bluetooth Adapter for the Bose QC2/QC15... I have the 14+ yr-old QC2 headset for reference. Here are my observations so far, I will add more as I am able to test more features:Adapter fit: it fits perfect - just like the original plug does for the wired connection. Very sturdy and no worries with connection.Bluetooth Pairing: paired to my Iphone 7 with no issues or trouble the first time.Signal Strength: I have tested with line of sight (in same room) up to about 35 feet-- stays connected. If I move to where there are walls between me and my iphone-the range seems to be about 25 feet (I will test more later).Sound quality: Music sounds as good as wired, no noticeable difference.Sound Quality TV and Movies: Have not tested yetControls: there are 3 buttons: on/off & pairing, track advance, track reverseInstructions: not great, but adequate, beyond on/off, pairing, and call control - there isn't a lot you need to knowCall Quality: So far everyone says they can hear me as good as if not better than a normal phone call , and I can hear MUCH better. The microphone for phone calls is located in the control that is on the end of the adapter cord (about 8-10" in length)--I just let the cord dangle freely and it naturally hangs about half way (vertically) between the level of my mouth and my shirt pocket...I can freely turn my head and it hasn't got in the way at all--I really can't tell it is hanging there. However, there is a clip provided if you want to clip in place.Cons: none so far, I will update as time goes on.

Really like this so far. Very easy to connect; syncs immediately. Wish the volume worked in smaller increments though. It's true that it sounds better via bluetooth than with the cable. So far so good. Solid construction. Great for biking. Clip can shorten length. Charges very quickly.Update (November 2017): Using it every day with no issues. Connects with cellphone and laptop quickly. The range is about 15 feet; not great, but adequate. The only complaint is that it says, "Your device is now disconnect" while turning off. It's obviously a grammatical error, and a tad annoying, but it reminds me every day how many things are made in China. Would I buy it again. Yeah, sure. With a 100% money back guarantee, who wouldn't?Update (January 4, 2018): Adapter stopped working. Contacted merchant and was told to request for a refund. Amazon was unable to give refund due to expiration of return date (September 2017). It lasted less than 6 months. I'd say don't buy this. Spend a little more and get something that will last. Good luck!

You can't pair with two items at once with this and I couldn't even get it to work when I would unpair my phone and then try to pair my computer. It still wouldn't connect and then going back to pair with the phone would work but often it would take a while for the adaptor to show up as an item I could pair with. The battery was also a bit underwhelming IMO. If I used it for maybe 4 or 5 hours just listening to music the battery would start to die. The final straw was phone call quality on it. Everyone would say I sounded too quiet or far away until I held the mic literally to my mouth to talk, even using the clip wasn't close enough to be heard. If you just want it to listen to music on one source it's not bad at all but if you need it for two things or good call quality I'd look elsewhere.

Once paired, this Bluetooth option sounds great on the QC15. Bass and treble is just as good as the wired option. Bluetooth, in general, has some lag if you watch movies/tv you will notice the delay in lips moving then sound coming. With music, podcasts or text-to-speech options, you will not notice any difference aside from the unwired freedom to move around. Saves me the need to buy a bluetooth headset.

I have owned other brands of bluetooth for the Bose QC15 headset, but today is the first day I have used this brand, WOW, I was impressed, not only was the signal strength outstanding and battery life, but it added a lot of depth the the sound quality of the music, I did not expect that, That is a 5 STAR in my books, KUDOS, Iphone Pandora music only sounds so so quality, but this really adds a lot of depth to the quality, Nice job!

I apparently have an older model QC2 headset. The jack will not insert into the headphone until you file off the plastic tab which must align with a slot in later versions of the headphones. Was able to file it off with a heavy-duty emory board with a couple minutes effort. No big deal. The unit paired with my MacBook without issue. However, I am getting static in the headphones which is not present when plugged into the MacBook with the wired connector. The noise is most noticeable when no music is playing. To be fair, I am using them in an office with overhead fluorescent lighting and maybe the BT is picking up some interference. I will give them a try later in a different environment.

It doesn't sound good at all, It has a difficult time connecting, and the buttons are not using the same functions as they indicated. I was disappointed with the quality of sound coming from this, it made my $200 headphones into $5 radioshack brand headphones. I highly do NOT recommend this product.

I wish the battery lasted longer (only 5 hours) but it is a nice conversion piece to make your bose headphones Bluetooth capable.
