Review on SEYOO Headphones Sport Earphones for Fishing - iPhone 6 (XG), Black: Enhance Your Fishing Experience by Sheryl Stewart

I am very impressed with this device. First my experience: I'm an electrical engineer and amateur audiophile. I'm not a hardcore gamer and my other passions dictate that my budget for audio gear should stay within a relatively modest range. The most expensive headphones I own cost $350. I prefer to research for a few weeks before making a purchase and I prefer best value over best money can buy, that's no problem. I'm in my 40's so my hearing in the upper frequencies isn't what it used to be. But I also understand how harmonic frequencies interact, and I understand that even though my hearing isn't as good in those upper registers, they still affect what I hear. The first thing that struck me was how small and light it is. . It's barely perceptible. It has a clip so I can attach it to my clothes and it doesn't support the weight making it wobble. The clip is good and has a fairly strong grip for its weight. If you attach it to your clothing, it won't go anywhere unless you really tug on it. Pairing was very easy. I used an iPhone X to pair and it found it and connected with no problems. I first tested them with the Apple headphones that came with my phone. I was a bit surprised at how they sounded. I compared it to the sound when plugging in headphones with the included 3.5mm lightning adapter. The sound was very close. I was a little surprised to learn that the wired adapter was louder than the Bluetooth adapter at max volume. It should have an amplifier, but it only puts out 20mW. The lower the headphone impedance the better as this will be maxed out into a 32 ohm load. So DO NOT connect high impedance headphones to it or you will be very disappointed. As far as I know, Apple headphones are in the middle at 23 ohms. But how do they sound? Most people really won't notice much of a difference between the sound of this device and the sound of a wired connection. This is achieved by supporting AAC (for iPhone users) and APT-X (for lucky Android users) (I REALLY wish Apple would support the APT-X standard, but an apple is an apple). AAC DEFINITELY sounds way better than the old SBC. The standard standard that really got Bluetooth a bad rap for sound quality. There's definitely a slight loss in audio quality, but the noise level is very good as I didn't notice the normal hiss or white noise normally associated with Bluetooth. because the main goal for me was to have a simple wireless interface for use in the gym. For this purpose they are great. I'll update this review after testing it with better headphones, but if you just want a wireless "dongle" alternative then this is a great option.
