Sennheiser SPORT True Wireless Earbuds – Bluetooth In-Ear Headphones for Active Lifestyles, Music and Calls with Adaptable Acoustics, Noise Cancellation, Touch Controls, IP54 and 27-hour Battery Life

Rubbish, useless, do not buy!!!
What do you want from headphones: sound, ideally sound from your device, ideally when you need or want it. Unfortunately look elsewhere if this is what you want.These headphones consistently fail to connect or think they are connected but don’t play sound or one side plays sound, or they play really quietly, or they disconnect, or they make fuzzy sounds.If it was one of the above maybe you could think it was a single unfortunate issue. If it was consistently one or all of them you could find a work around. The most frustrating part of this is that it is one or two of the issues at seemingly random times.I have spent time researching, lots of advise but sometimes the advice works, mostly it doesn’t. Sennheiser have a basically non existent customer service.I do not have lots of money, this was quite a special treat for myself and it has been incredibly disappointing.

Amazing battery life and quality sound
To start off with most aspects of this product are very good, the sound quality is excellent with crisp highs good mids and deep lows, no muddled bass, the volume isn’t as loud as AirPods for example but it’s high enough to deliver loud music without hurting your ears, with no distortion on high volumes. The battery life is absurdly long, I charge these once every 3 weeks and even then the charge has never dipped below 25%, with daily use during commutes on high volume. Fitment is good with 3 different sizes of tips to use, it’s important to experiment with these as I found the medium tips can cause pain for my ears, whereas the large size fits better and causes no pain or discomfort with long wear time, I settled on using a medium tip on one and a large tip on the other because apparently my ears are a little different. Noise cancellation on these is good enough for me personally, I use them in busy town centers and have no problems whatsoever, and the transparency feature while in a call or activating Siri can be very useful to hear what people are saying. Sometimes the left side will not connect, this has happened once in the 2 months I’ve been using them, with a simple solution of placing both buds in the case, holding them both down with fingers for 40 seconds, and then using them, this fixed the issue immediately, this occurs because the right bud connects to the phone and the left bud, and sometimes the right cannot connect to the left. They are a little large, but don’t look obnoxious or strange at all while In the ears, I would prefer a smaller case or perhaps a more flat case, as the rectangular shape of the case can make it awkward to store in pockets. Overall I am very pleased with the product, with very minimal issues during use, and a good rich sound with long lasting battery.

Perfect for the gym, but design-limited short life expectancy
I’m editing this review because I’ve just been informed of something by Senhheiser, after contacting them about an issue I had with the earbuds.It seems that the earbuds do not power off if not put back into the charging case, leading them to discharge over a few days even if not used (not even connected to anything; the phone was turned off). Why is this an issue…?Because keeping them in the charging case keeps the lithium cells 100% charged. That is absolutely terrible for their life span and *will* make them fail earlier. If I could keep them out of the case and only recharge (preferably not fully) when needed, I could do that once a week at most with my use and the cells would probably live twice as long. That stuff is pretty much common knowledge now.With this design, the earbuds will die in half the time they otherwise might. I’m very unimpressed with that.Original review:Sitting on a rowing machine for an hour is boring. With these comfortable earbuds, I can enjoy that hour instead of wishing it was over. The earbuds appear of good quality and the fit into the ear is well designed. There is no slip at all with the right-sized hook selected. So far I’ve used them for a two weeks after a full charge, training every day and deliberately not recharging them to test the battery out. I’ve still not had a low warning (I’ll charge them now though – don’t want to run them down too far). They’ve survived sweat and rapid rowing without a hint of loosening and are proving durable and very good value. Sound quality is excellent for the price (I’m comparing with my main headphones that cost £600).

Have them now since 8 monthd and they work without any problem. The sound quality is fantastic.

Can be a bit of a task to get them to sit correctly in the ear – to be fair though, there are multiple different size of buds/plugs provided.Biggest gripe though is that while the sound quality is very good, it just isn’t loud enough.I use them for running and they barely drown out my feet slapping against the road, or my gasping breath.This is even when using volume booster apps.I’ll play around more to see if I can improve, and if so – extra star will be added.Okay – used them for a few months and for the update I have removed a star. They are just not loud enough and they are far too fiddly to get a good fit in the ear that lasts for more than two songs.So build quality really good, sound quality really good, volume terrible, and fit/comfort…? Well, I’m going to buy a different pair because I’m fed up of having runs ruined having to constantly reach up and adjust them!!!
