Brilliant headphones easy to use

Husband and I have both used these out jogging and find them really easy to use and good sound quality. It’s fab hey stay charged so long and go into hibernation mode for so many months. Music when jogging makes it so enjoyable and I really think these headphones have been nicely thought out being reflective and having a pouch to keep them in. The extra sizes of eartips are also fantastic as they make them fit much better. They are also very stable in my ears when jogging and comfy too.

Pros: Ease to use, Good build quality, Looks good

Perfect for my longer runs and the summer heat

I am doing more running at the moment, just as the weather is getting hotter too.... Yeah, I know! I usually wear over the ear headphones, but in this heat of the summer or when I am traveling and running or in the gym I like to be able to move more easily, have less sweaty ears (I know that sounds gross, but we are talking headphones and fitness here!) and also have all the features I need for when I am working out. That's where the BackBeat Fit 305's come in. I already own and use the BackBeat Fit first versions in green and orange, they are lovely and have served me well. These new versions the 305's are amazing, a real refinement. I love the braided cable with the reflective material in it for night running, a really nice safety edition there! The battery life of 6 hours is nice and long and in my few weeks of using them I was able to get 5 and a half hours from a full charge and a 90 min charge to get them refreshed to 100%. The ability to take a call while running was a nice feature that I have used a few times already without fault. However, the bulky button section was slightly annoying when at pace on the treadmill or on the road as it banged against my neck a lot. I was able to forget about it after a while, but it was slightly annoying compared to my previous versions which had the buttons in the earpieces. Another issue I found was the wingtips for my ears were fiddly to get in, maybe took another 20 seconds to get them secure compared to the previous version because they were very flexible. Something I can get used to I think and wouldn't put me off using them as the sound quality is wonderful and rich with its high treble and sweet mid-range. It didn't have as much bass as I was expecting, but with some customisation in my music app, I was able to get it much more my preference. All in all a wonderful all-rounder headphone set and will look forward to my next marathon in them.

Pros: Rear clip for keeping them in place, Reflective strip, Battery life 6hrs!, Pair more than one device, Application for more configuration Cons: Sometimes hard to get the wingtip in, Bulky buttons

Sporty Spice

I'm just getting into running - and I bought a pair of headphones that were supposedly designed for this purpose. They we're awful - kept falling out all the time. These have a strange, soft loop that sits perfectly into your ear - leaving a really secure fit. They honestly haven't fallen out once. They're also sweatproof, so you don't need to worry about them breaking if you're running hard or in the sun. The sound quality is good - just what I need really - I'm not going to be bothered too much about soaring high notes and deep bass while I'm totally and utterly out of breath trying to run up a hill somewhere. All in all, a great little set of sports headphones - and they actually look really good too with a gradient type thing going on. Smashing.

Pros: Sweatproof, Decent sound, Don't fall out, Looks good
